Very Sharp
Drill bit is sharp and stays sharp. No complaints.

Works great - (until you hit a nail)
Cuts through 2x4s like butter. Got through about 60 studs (and a nail or two) before it was too dull to continue.

Great Bit for Boring Studs for Wiring
Very sharp, I have drilled a couple of dozen holes and it is still sharp. On great thing the bit does is grab the wood and pulls itself into the wood. So, you don't have to push hard on the drill.I bought another brand, and haven't even opened up that package.--Cooper

Fast and sturdy
Much shorter than the regular type, perfect for getting into tight places. Pair this with a compact impact drill. I have ordered these a few time now they kick ass, avoid nails or they're toast

This is an amazing drill bit
This is an amazing drill bit. I bought it to drill holes to run wiring. It punches through a 2x4 stud wall with ease, and is through in 2 seconds. Highly recommend this bit.
