Yes, this. Do not put a cutting wheel on a drill press directly. The spindle is not configured for side loads and could pop right out, and you will not have a good time. In this case, there is a heavy-duty arbor supporting the cut-off wheel from below (under the tarp), and the drill is only providing the torque from above, with a double-U joint to compensate for misalignments.
Mostly I do lapidary work, not metal. I don't have the space to set up a flat lap machine, so I put a lot of effort into adding that function to my drill press. Sturdy base, strong motor, already taking up space. Got Covington Engineering to make me a custom arbor by assembling one of their standard ones upside down, so the wheel mounting flange is on the same side as the housing support flange. Pressed a sleeve bushing onto the housing to raise the diameter slightly, and I can swap it out with the table on my drill press with a secure fit. Couples to the drill with a Lovejoy DD3 double U-joint. (The bottom of it was drilled and tapped to fit the arbor, the top gets chucked into the drill.) Typically used for grinding, sanding, and polishing stone, inside a tub with a constant water spray. I took that apart to jury-rig the saw. Only new thing I bought here was the tarp.
