Hello All-

I am a new woodworker, and have a question about some drilling of 1 inch counterbores drilled 3/4 inch deep into a 2X4 frame. I am using a Dewalt corded drill, it is about 5 years old, and 5.5 amps. When I attempt to counterbore it does not seem to do it with any ease, and begins to make the bit smoke and blacken the hole inside. Is my drill not powerful enough for this task? If not, what type of power drill do I need, 18V?, 14V, corded 10A?

Thanks!

Nick

Sounds to me like the bit is dull. What type of drillbit are you using?

I assume you mean construction lumber when you say 2×4 – like a framing stud, right? Your drill should have plenty of power for that.

You may be turning the drill bit too fast. Try slowing the bit speed down so the bit can dig in. You may also have a dull bit. Is it new?

I would guess a dull bit is more than likely.

One of my helpers had the drill going backwards. It burned.

Your burning of the bit is probably due to too high a speed. Your one inch bit needs to be driven with a lower speed higher torque drill. Your drill does not have enough torque for the job.

After rereading your post, I hate to say it, but I think you’re using the drill backwards. I don’t see a corded drill ever having a problem drilling into a 2×4.

You should be using a forstner bit to counterbore.

You also need to watch your drill speed with larger forstner bist. They burn up very fast.
