I have a set of Forstner bits that go up to 3 1/4". It's been my experience that any size larger than about 2" cannot be used in a smaller drill press. I always use my Delta floor standing drill press with the 1 hp motor and move the belts for a very slow speed to get as much torque as possible. These big bits really do require a lot of power. Neither of my table top sized drill presses can turn these large bits, so I doubt that the drill press posted will do the job. Forstner bits don't leave that clean of a bottom in the holes either.
For a candle recess, I would make a router template sized for the router bit and bushing combination that would produce the hole size that I need, and use one of my routers to make the desired hole(s). The template can be attached to the work with double sided tape and re-used over and over. For that project I would make the template with all of the holes, so I could attach it once and then cut all of the holes at the same time. They will all end up exactly the same diameter and depth, and even with the same spacing, if done this way. For high production, I would probably use 1/4" Baltic Birch plywood for the template. If you will only be using it a few times, then 1/4" MDF could be used. Attach a side and end guide to the template, so it always gets positioned the same distance from the side and end of your work. You will likely want new tape for each use, but don't use too much or you may have trouble getting the template off later. Using a router with the right bit will produce a much higher quality cut and a perfectly flat bottom with no edge groove and no center tang hole.
