I have a Delta 10” drill press and 1/4 HP. I am trying to drill a 2 1/2 in hole in several different hardwoods. With very little pressure the drill binds or stops – even tried a brand new bit. I was attempting to make a bracelet blank using some Mango and Monkey Pod. Is my drill press not powerful enough for this?

You did not mention what speed you are trying to run the drill.

1/4 hp is way under powered, but could work if the speed was slow enough.

Most small drill presses with small motors seem to be designed to further piss you off by not going below 500 RPM.
Won’t work. You need to be at 200 RPM or less with a bit that size.

You might have better luck with a hole saw.

600 RPM is too fast for a bit that big. You might be able to get away with 400 RPM, but 300 or even 200-250 would be better.

Sadly, if that’s as slow as your drill press goes, then you are out of luck. Any friends that have floor-standing DPs that you could use to make the holes?

Clamp your board down so it cannot move. Dill through with 3/4 bit and then redrill in 1/2” incriments.

Your DP is under powered.
