3 Pcs SET Diamond Hole Saw Drill Bit Set Granite Glass Tile - Tools 3 Piece Diamond Dust Hole SAW Drill BIT for Ceramic Tile Marble Rock Porcelain - 1/2" -3/4" - 1" Inch In https://smile.amazon.com/dp/B00DRRDFXC/ref=cm_sw_r_cp_apa_i_aakxCb1KKKR9K

I use this set from Drilax. I think anything smaller would be useless for drainage. I borrow my boyfriend's drill. Watch YouTube videos on how to do it, but essentially you want to squirt some water at the drill site, having it wet constantly so it doesn't overheat. You don't need to put all your weight on it, but you will need at least a little pressure. What helps me is putting pressure only on one side of the bit (it's a miniscule slight angle) whenever drilling, and switching/rocking occasionally from different sides. It really helps deepen the cuts. This also helps when you're starting to drill (keeping it on an edge rather than directly flat down), otherwise your bit will bounce all around the bottom of the pot (you'll still need your other hand to steady the drill for the beginning cut... Maybe even your feet to stabilize the pot, lol).

I know when I'm about to break through, because the water I squirted onto the pot will suddenly run through. And because I'm drilling at a very slight angle, I only have a semicircle hole, and I just have to rotate my pressure on the other side now. It's a rather gentle finish and I've never broken a pot!

I hope some of that made sense. Sorry for the wall of text. Good luck! It's super fun!

Yes! Do it. I was riding that high for days drilling holes in everything. I know for a fact my boyfriend is hiding mugs and glasses from me but cant prove anything yet.
I bought a big glass fishbowl, drilled a hole and put my fern in it.
You can drill holes in the rims of pots and hang them with twine and s hooks. I’m still realizing the full potential.

For reference, I bought a $40 black and decker hand drill and these drill bits:
https://www.amazon.com/Neiko-00823A-Diamond-Drill-Piece/dp/B00ODSS5NO

I start the drill out on full blast with barely any pressure and then apply greater pressure gradually. Always keep water on it as others mentioned. Hope that’s helpful and good luck :)

No worries at all. Not only do you have your own life, you're on the opposite side of the world from me. I've really enjoyed this discussion - not only am I able to help you out, but you're curious about a subject I love. Basically a win/win for me. :)

I honestly couldn't tell you how many teeth snakes have. I've seen maybe 6? on Puppy.

Those pictures are actually a few months old. She's going to shed tonight or tomorrow, though.

--------------

I bought this pump and filter combination, and this bowl to use as the basin. I also purchased some PVC pipe (3/4" inner diameter I think, 1" outer diameter), a couple sheets of flagstone, some flexible tubing (5/8" inner diameter, 3/4" outer diameter - so it fits inside the PVC pipe), some large diameter black pipe for spacing out the rocks, some gravel, and assorted fittings for the PVC pipe.

I built the frame out of the PVC pipe - you can see it a bit in the picture. It's the white pipe. The frame is composed of a rectangular cube, with T-fittings around the bottom edge. Each of the Ts points inward. I then have a single fitting that takes in all four of the Ts and lets you send a central pipe straight up. The gravel is in the bottom of the bowl, and the frame sits on it.

Next up, I cut the flagstone. Flagstone breaks in straight lines, so all you have to do is get a chisel you don't care about, score the line that you want to cut, and then put the chisel in the score and smack it with a hammer. It will break along that line.

Next I used this 1" diamond core drill bit to cut holes in the center of each piece of flagstone. The holes wound up being slightly too small, so I used these diamond files to make them wide enough to fit the PVC pipe.

Then I put the stones onto the frame, using the black spacer pipes between them.

Now, in order to get the water to actually flow, I drilled a hole through the center pipe in the frame, below where the lowest piece of flagstone sits and fed the flexible tubing through that hole and up to the top of the waterfall. Then I hooked up the pump to the flexible tubing.

Last but not least, I got a lamp dimmer and connected the pump's power cord to it. So, I basically have an on/off switch for it. That's necessary because the waterfall splashes a bit. If I left it on all the time, it would soak the substrate.

All told, the waterfall took months of work and a lot of mistakes. The final product turned out well, though.

------

If you have the freezer space and your snake cooperates, f/t is the way to go. It's the cheapest and safest option.

I feed Puppy live, but that's because she's a very picky eater. She refuses to eat anything unless it's alive. I recently switched her from a species called African Soft Furs (bigger than mice, smaller than rats) to regular old rats, which she didn't like at all. The entire process took around 3 months of hard, moderately traumatizing work.

However, that's a very specific issue that happens with carpet pythons - they get fixated on a single food source and can refuse to switch. I doubt you'll have that sort of problem.

One more thing - usually you want to let your snake digest for 1 - 3 days after you feed them. If they are full and become very bothered, sometimes they will regurgitate their meal. That is definitely bad.

----------

Yeah, ideally the shed will be in one single piece. The shed is actually longer than your snake is however - as they are shedding, the skin stretches to let them get out.

What I'd suggest is looking at the skin initially. You should be able to see the eyecaps on the discarded skin, the tip of the tail, etc. If you do notice stuck shed, there are a few common approaches:

1. Soak them in a tub of reasonably temperatured water for like 15 - 30 minutes, then pull it off by hand.
   
2. Put them into a damp pillowcase for a while. The moisture will loosen the shed, and the pillowcase will give them enough friction to rub it off themselves.
   
   Shedding is hard work, so I usually feed them a large meal, let them rest for a few days, and then hang out with them. However, it's totally cool if you want to hang out with your snake immediately after a shed, as long as your snake isn't acting stressed.

go for the diamond dust bits. I just recently got a set of them and they changed my life. Well maybe not quite like that but they're leaps and bounds better than the arrow head looking ones. I got a set of 5 off Amazon for a little more than $10 and could not be happier with how they performed. Couldn't find any at my local Home Depot. The only issue is that they only go up to half an inch in diameter and the smallest downstem i've found is a tad larger than that. There is a set of bits by the same brand for like 30 bucks and they go from the next size up to like an inch and a half diameter but i'm not sure if i'm ready to upgrade to those just yet. It would make drilling holes for standard down-stems exponentially easier, but I don't do that kind of thing with any regularity. To make the holes bigger I have used a conical grinding or sanding drill bit but make sure you use water to keep everything cool (especially the diamond dust bits) and be patient. I've cracked many a bottle pretty badly due to impatience and improperly cooling the bit.

Oh and the brand is Neiko

Use a hole saw for terminal cups. It's really difficult to cut a hole that small with a jigsaw and have it precise enough for a terminal cup.

TBH, most of us don't use terminal cups. Drill a hole, push the wire through, put a dab of caulk/silicone on the inside. Straight connection=lower resistance=more power. Plus, easier and cheaper.

As for cutting the subwoofer holes, using a jigsaw is certainly a skill you have to develop. It can be done, but honestly, it requires a lot of practice. Once you develop the skill, you can do some pretty cool stuff.

For instance, except for the straight side cuts, I made this with a jigsaw, including cutting out the logo. Triple layer baffle, you can see how close each hole is (sorry for the bad picture, this was from years ago). They were all cut separately, freehand, from precisely measured and drawn lines.

Unless you want to put the time in practicing, best bet is a router with a circle jig. Find perfect center, drive in a nail, pop on the jig, plunge and spin, perfect hole.

Super easy! With this set of bits , At first I used one from the hardware store that was expensive, but made small holes and took FOREVER.

I just have like a 30 dollar drill from Walmart. I put the piece on my door mat on my porch, pour a little water (You don't need a hose but I have about a cup of water and add a little as needed) I start the drilling at an angle and then slowly raise it up until its straight up and down. Having a sticker on the bottom helps to have something for the bit to grab into. I'll try and do a video as it's way easier than the videos I saw on Youtube. You do want to have your hand on the piece though, the only thing I broke was because the drill went through the bottom and swung the piece around, that's before I was doing it on the mat to help with slippage.

I got these diamond coated drill bits for like $10 that work like a charm. I drilled the initial hole which was too small, but because the bit is coated on the sides, you can expand it gradually. I love them and highly recommend them.

Then, there's how I was able to get it in at an angle. I made the hole and ellipse, not a circle, because I'm not using a grommet to seal it and the intersection of a cylinder and a plane at an angle i an ellipse. Then, because these drill bits can almost be used like dremel bits, I just went along the edges at the angle I wanted.

I feel like every plant lover should have a set if these. Or if you don't know what to get your plant loving friend... Get them these.

I find awesone pots all the time for cheap at ross, or goodwill, then just drill my own holes! Free yourselves from the agony of a beautiful pot at a great price with nooo holeeesss.

For the cables below the desk, I would suggest adding these things to the bottom of the desktop or on the wall behind the desk just below the desktop to clean up cables:

1. J channel raceway for cables
   
2. cable management box for the power bricks and surge protectors
   
   Above the desk, some velcro ties and maybe some braided cable sleeving should help clean up.
   
   I think the best look is to have every wire coming out of the back of the PC geting wrapped up in 1 sleeve, then dropping below the desk (via a grommet) into the J cable raceway into the mounted cable management box, then 1 power cable comes off of there to the outlet.
   
   Lastly, here are some grommet drills, grommets and some monitor mounts with cable management built in. The mounts will help clear up some deskspace (I have LG ultrawides and that half circle stand base eats up some space) as well as provide some ports for keyboard and mouse.

If you have a drill, you can buy a diamond drill bit and drill holes in the bottom of your pot pretty easily. I just ordered these on Amazon and got them yesterday:

FireKingdom 5pcs 12mm 1/2" Inch Diamond Drill Bit Hole Saw for Tile Glass Marble Granite Fiberglass Ceramic Tool https://www.amazon.com/dp/B00O1SAY58

I cut holes in 5 or 6 pots last night and it worked great. And now I can go to thrift stores and find cute containers to use :)

Diamond Drill Bits, Baban 10Pcs Hole Saw Diamond Drill Bit Hollow Core Drill Bit Set for Diamond Coating, Carbon Steel for Glass, Ceramics, Porcelain, Ceramic Tile, Marble, 6-32mm https://www.amazon.com/dp/B01L92YM1A/ref=cm_sw_r_cp_apa_i_x.QUCbVDBJFS2

/\ get some of these and a 14mm downstem on eBay. 14mm is the way to go cuz you can dab with it too. Just make sure to practice drilling glass at least 10 times before you risk that beautiful bottle. Best of luck!

Get yourself some masonary bits for your drill, mine were about 15$ on amazon. hit the thrift shop/yard sales etc. anything you like can be a pot. shallow pots are better than deeper for succs. i use egg cups, candy dishes, cannisters sets, flower bowls, serving dishes, soup bowls, etc. your choices are endless and it is a way cheaper option, especially if you have 50 or 60 of these things like i do. i also got glass bits for my drill and so have some really pretty glass pots as well.

if you want a store option, terra cotta pots are cheap and you can find them in any big store like walmart etc. sometimes the thrift shop has those too...and if they are a bit grungy, i wash them really good with soapy water to ensure no parasites, let dry then use a sanding block to sand away the grime or discolouration.

if your succs can stay outdoors, you can use concrete blocks (or make concrete pots). drift wood etc.

edited to add some links/info.

EDIT Again! here are some of the great pots i've thrifted and drilled. https://imgur.com/a/4ztbWmn

Yep! Diamond hole saws, $15 for a 15 piece set on Amazon. I like them SO much better than a masonry bit, and they're significantly cheaper too. They also don't get very hot, I use a spray bottle but it's more for visibility than cooling.

https://smile.amazon.com/dp/B076X52RN4

Earlier today, before drilling the mug, I added three more holes to a large pot before repotting my ponytail palm. https://i.imgur.com/qcDN6Vy.jpg

It's awesome for cups, bowls, mugs, basically anything that will hold water can be turned into a pot. :) Thrift stores and dollar stores are a goldmine!

BLENDX Diamond Drill Bits - Glass and Tile Hollow Core Drill Bits Extractor Remover Tools Hole Saws for glass, ceramics, porcelain, ceramic tile, Pack of 10 https://www.amazon.com/dp/B01MR1HTLH/

These are also useful. I use a dry grinder attachment for the common holes but carry a pack of these in the van for tasks like yours. You'll want a guide and to be honest that burr set may be easier to use. These still have a place.

So hit the local hardware store and buy a diamond tipped hole bit like these. Do this at an angle to start to keep the bit from walking (and scarring your glass) while having running water on it. If you need a friend to help with the hose or spray bottle then use them. Heat will cook the moderately expensive bit and well as crack your project. After you get an edge to bite work your drill to 90* and keep the water coming. This will cool and lubricate the hole your making. Wear safety glasses, you're essentially chipping tiny pieces of glass, ceramic, or clay. If the end turns blue/purple from heat, the bit is cooked and throw it away.

I have this bit set which was super cheap on Amazon, and I have used those to put drainage holes in TONS of ceramic pots! It's super easy, I spray water on them to keep the temp down while drilling, and take it at a medium speed.

My tip for starting the hole (that's the hard part), is to start at an angle, get a groove in it, and slowly tilt the drill up until the circle is flat on the surface. I haven't broken or cracked one yet. :)

For anything I find that doesn’t have holes, I use some diamond tipped drill bits to drill holes. So far, most coffee mugs are super easy, but I’ve only done one ceramic pot, and it worked out well enough. I use this technique with drill bits like these.

Besides that, make sure your arrangements contain compatible plants: similar watering, similar light needs, dormancy, etc, and you should be good!

I've been hugely impressed with all the Dewalt impact ready accessories I've used so it wouldn't surprise me if their drill-taps are the best out there. The impact ready hole saws and step drills are incredible also.

I use something like this, and haven't broken a pot yet out of 50+ holes drilled! I keep a little puddle of water over the spot where I'm drilling, or at least keep it as wet as possible, to keep it from heating up too much. Honestly, it's been AMAZING, I have so many amazing pots now, including converted pitchers/cups!

Something like this would work better, both for you and the plants. Bigger holes are better and will allow the pot to drain more easily.

As everyone is pointing out the need for drainage, it can be done very easily by anyone with just a regular power drill and one of these kinds of bits.

Pour a little water on the surface you're drilling into and wear eye protection (as you should be doing when you're drilling anything anyway!) Let the bit do the work and you'll get nice, clean holes pretty quickly.

Your best bet is to use a diamond hole saw. You can get a set of small ones for around $10 at Harbor Freight Tools. You'll want to drill under running water or use a light oil to lubricate as you cut. Put a piece of painters tape where you want to drill to help hold the bit in place and avoid scratching the glass. I highly recommend having a couple practice bottles to work on before trying the real one. It would be best if they were the same type, but similar will work.

Edit: I can't find the diamond hole saw set on harbor freight's website, but this one on Amazon is similar, but more expensive: http://www.amazon.com/dp/B00CY3U7QI. If you know the size you want to make the hole, you can just order the one you need individually, I'm sure.

I bought these: https://www.amazon.com/gp/product/B00ODSS5NO/ref=ppx_yo_dt_b_asin_title_o07__o00_s00?ie=UTF8&psc=1
They work great, just remember to spritz with water often while you drill so you don't strip the bit! I'd suggest watching a few youtube videos so you can get a good idea of how to do the actual drilling part, but it's super easy and I have yet to wreck a pot while drilling a hole.

I just drilled my own holes for the first time yesterday! I was in the same spot, so many pretty pots but no drainage. I bought this set off Amazon https://www.amazon.com/Neiko-00823A-Diamond-Drill-Piece/dp/B00ODSS5NO/ref=mp_s_a_1_3?keywords=diamond+drill+bits&qid=1564513905&s=gateway&sprefix=diamond+dri&sr=8-3
I drilled 3 different pots yesterday and it was super quick and easy. The world will be your oyster!

Awesome! If it's your first time drilling into glass, practice a couple times on similar bottles first. Also make sure you're using a hole saw like this:

http://www.amazon.com/Neiko-00824A-16-Inch-Diamond-5-Piece/dp/tech-data/B000UF5V18

2" sspade bit with a hand drill is still pretty sketchy. You can get something like this instead.

I haven’t tried yet, myself. I’m going to get some of these , I think. Also, as I understand it, you want to go slow & frequently cool things down with water. Good luck!

All I used was a drill and [one of these diamond drill bits] (https://www.amazon.com/BLENDX-Diamond-Drill-Bits-Extractor/dp/B01MR1HTLH/ref=sr_1_6?ie=UTF8&qid=1494215602&sr=8-6&keywords=diamond+drill+bits). I just wet the bottle down in the sink and drilled slowly at first to establish a groove then it's pretty easy to just keep it in place until you're through. If you already have a drill you can drill any bottle with just some of those bits.

I've seen someone on youtube drill a hole in a piece of wood to hold these bits still & he had great luck drilling holes in bottles & glass!

Yes. Diamond dust is an excellent industrial abrasive. Here are some diamond dust based cutters for example.

Occasionally gemstone dust is used to make a paint sparkle, but there are other substances that can do this.

I bought this exact set about 6 months ago for $9.99, free shipping, I love the bits, they cut so smoothly.

Sorry for taking so long to respond.

We held the drill on an angle we wanted while drilling the hole. Used a drill we thought was the size too small but with the angle it ended up perfect.

You can get special bits on amazon. Like these https://www.amazon.com/Neiko-00823A-Diamond-Drill-Piece/dp/B00ODSS5NO/ref=sr_1_6?keywords=drill+glass&qid=1569519750&s=gateway&sr=8-6

I'm gunna be a dick and say I told you so. But anyway... Here's a cheap set of bits that will last a long time if you take care of them properly.

You can cut an array of different sized holes with these.
As for the gravity bong idea you should take a look at the product called the kinkajou. It's basically a mounted glass cutter for bottles. If you've got some carpentry skills you can make a brace with your glass cutting tool to cut bottles perfectly. Honestly if you get the bits all you'll need is a hole. Here's a link to a homemade bottle cutter you can make with your glass cutter: https://homemade-modern.com/ep01-diy-herb-garden/

Bits like these, plus lots of patience and hand cramps.

https://www.amazon.com/dp/B00ODSS5NO/ref=cm_sw_r_sms_c_api_HU8-yb2HD7P35 these have been perfect! Just stop every minute or so or if you hear squeaking and pour water on the area you're drilling and you're good to go.

Depending on the size hole you want to cut, get this type: https://www.amazon.com/Diamond-Hole-Drill-Granite-Glass/dp/B00DRRDFXC/ref=pd_lpo_469_bs_lp_img_2?ie=UTF8&psc=1&refRID=GEGR9BY5JSS4KGAVHABX

Most glass cutting bits will be diamond coated, and they aren't expensive. I got a 1/2 inch size bit for cutting holes in bottles, and the type I linked handled that far better than the normal style bits (also diamond coated) without cracking or chipping the glass.

The important thing is to take it slow, and don't press too hard on the glass, let the bit do all the work, and have it supported underneath to avoid cracking and chipping.

Will this https://www.amazon.com/gp/product/B00ODSS5NO/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 hole saw set fit directly onto a tool like this https://www.amazon.com/BLACK-DECKER-BDCS20C-Lithium-Ion-Rechargeable/dp/B00TM2T9C2/ref=sr_1_1?s=power-hand-tools&ie=UTF8&qid=1478632498&sr=1-1 without any other drill bits or adapters? I plan to make holes in glass with this.

Thanks man :D and I used a 1/2 inch diamond drill bit and the rubber grommet is also 1/2 inch that I got at my local hardware store. Diamond Drill Bit Link

diamond drill bits are useful for that, here

I just recently bought these after getting some recommended to me from Home Depot that did NOT work. I also used this guide that advises using water to keep the drill bit cool and to start at an angle so it doesn't dance around. The drill bits work in 5-10 minutes even going super slow. My plants are now in various coffee mugs and things I normally would reject as they don't have drainage.

Edit: Also check Harbor Freight if you have one nearby.

I bought these. You've really got to follow the instructions that the one commenter mentions but the hollow ones work way better than the drill bits that are really only for drywall.

Okay, so this is the mandrel I want to get and the hole saw I want to use. This would be fine you say?

that one seems a bit big, possibly smaller ones are cheaper?

Diamond drill bits work on glass and ceramic. I just did this for the first time and it was really easy, didn't break anything!

I just ordered this and I'm finally gonna make my Vodka Spirit Bong into the bong it's been waiting to be transformed into. Probably gonna need a grommet and I'd like to find a way to make a perc although I'll probably buy a downstem with either slits or a tree perc

Hole saw sizes: 1 1/2" for the smaller/lower hole, and a 2" for the larger/upper hole. These sizes typically come standard with a hole saw kit ($14.02): https://www.amazon.com/Black-Decker-71-120-Assortment-5-Piece/dp/B0009ZAEY8/

NOTE! The official IKEA FIXA hole saw kit does not come with the correct corresponding sizes!

My specific hack requires a grommet to achieve a tight yet adjustable fit while utilizing standard hole saw sizes ($7.49): https://www.amazon.com/HYCC-Flexible-Desk-Grommet-Color/dp/B01KNXAPK8

There are other kinds/brands of bits that can do the job, but I'm a fan of these.

Protip: use a 2" hole saw on your drill. Makes nice big holes. Make your tools do the work for you. You can find a hole saw with a mandrel (the center thingie) at any hardware store. Or order a kit on the cheap: http://www.amazon.com/gp/aw/d/B0009ZAEY8

I would go the route of a diamond tipped hole saw. They arent that expensive, particularily only if you need one or two sizes.

Linky

Any particular advantage of a forstner bit over a hole saw?

I purchased a Pelican 1300, and I drilled out two holes on the top (~ 1" space on each side). I then threw in two waterproof speakers making sure that it was sealed tightly (required some calk).

I stripped the RCA side of a 3.5mm jack to RCA cable and soldered the ends to the speakers.

You have a welder, a digital level and a Dremel.....but not a $10 set of hole saws?

As a toolmaker/CNC programmer, your methodology made me twitch, but I can't argue with your results!

I used these to drill several holes in thick glass brick. Go slow, especially with larger ones, and use plenty of running water to cool and wash away glass dust. Use a drill press to keep it straight and provide steady light pressure. They have similar larger ones.

I used a glass/tile drill bit while it was immersed under water and then largened the hole with a dremel and and a grinding stone to get it to size. I just ordered this set of bits off amazon as the one I had was much to small and took forever to grind up to size.

Glass Drill Bit

I was being nosy and I think someone had posted here of these drill bits. They came with different sizes.

They're actually quite affordable.

And u/laspyra

Get a diamond tile drill bit! Then you can drill a drainage hole in everything!

Typically, a drill and the appropriately sized hole saw bit are what you would use.

I bought a hole saw kit, just for this purpose.

Based on this frequently bought together item that comes up with it, I don't think most people are using this tool to make glasses.

Unless your wet saw has an actual specified "glass blade", you might find it will chip the glass as well as the backer paint. Not to mention being really slow. You'll find a Score and snap tile cutter much easier to cut that glass with. Cleaner cuts and way quicker.

Start in any corner. Throw the odd level line on with a pencil as you go up. And don't use mastic (glue). Use a white thinset with a 3/16ths" V-notch.

Use one of these bits to drill your holes. Hold a wet sponge against the bit as you drill. Shouldn't take more than 30-60 seconds per hole.

someone here recommended these to me. I just got them in the mail but haven't had a chance to try them yet.

You can drill through ceramic with a diamond bit. Drill slowly, irrigate, and you need to use a sacrificial plate of some kind to prevent blowout/chipping on the exit point (unless you're not too concerned with cosmetics). Glazed is a little trickier to work with.

Buy one of these.

Attach it to a drill, and bore through the glass by letting the drill bit do all the work.
Run water on the drillbit while it's grinding through the glass, it prevent cracks from forming.

I use this set of drill bits I saw suggested on this subreddit. I have used them for several pots with no issues or breaks so far. https://www.amazon.com/dp/B00DRRDFXC
