### ⭐⭐⭐ 







  
  
    not able to keep from slipping.
  

*by W***N on Reviewed in the United States 🇺🇸 on December 31, 2022*

If the shanks had three flats ground on them like some of the better quality drill bits, they would be real winners.

### ⭐⭐⭐⭐⭐ 







  
  
    These countersinks are the best I have ever used
  

*by K***N on Reviewed in the United States 🇺🇸 on August 18, 2016*

These countersinks are the best I have ever used. I am a machinist and so I use these every day. From chamfering a hole to countersinking for a flat head bolt, these do the trick with no chatter or burrs. You do have to be careful if you are chamfering a diameter with a very heavy burr on it free hand (like plastic loves to do), you will probably end up with a lopsided chamfer. This is not the tools fault, but your own.For the professional tradesman...these are the way to go, I have tried more inexpensive styles and was greatly disapointed...break with the bucks and buy the best .

### ⭐⭐⭐⭐⭐ 







  
  
    Best Countersink Bores I Have Ever Used!!!
  

*by M***D on Reviewed in the United States 🇺🇸 on December 20, 2016*

I was way more impressed with these that I would have predicted.  I use them for wood working and they bore clean and precise countersunk holes (using a drill press - have not tried them with a hand drill).  They produce a smoother cut and extract the debris significantly better than traditional countersink bores.
