I used one these last week, and ran right out and bought the kit. If you need to punch holes in drywall, studs, or anything non-precision. This is the bit for you. They WALK right through a stud no problem.
Now, I must say that I was using my DW Impact driver with them so I know that helps, but I put a 1" hole through a floor joist in about 3 seconds. I could not believe how fast they cut, and for 30 bucks for the full set. Worth every penny. :thumbsup:
