### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Very Sharp
  

*by R***N on Reviewed in the United States on December 14, 2023*

Drill bit is sharp and stays sharp. No complaints.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Works great - (until you hit a nail)
  

*by R***O on Reviewed in the United States on May 26, 2022*

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

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great Bit for Boring Studs for Wiring
  

*by C***R on Reviewed in the United States on April 2, 2020*

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
