## Customer Reviews

### ⭐⭐⭐⭐⭐ A tool box must-have.
*by R***A on June 5, 2025*

I love this bit; working on wood, metal, and plastic. Nice clean cutting; makes project assembly look proffessional.

### ⭐⭐⭐⭐⭐ Performed better than expected
*by E***E on April 24, 2025*

I was unsure how good these would be compared to other brands I bought. But decided to give them a try. When used with a drill press, they perform well when the piece being countersunk is clamped down. If using with a cordless drill however, it is a bit more difficult to get a symmetrical countersink. I’ve used them to countersink 3/8” plate steel for 5/16” bolts and they performed better than expected. I also use them to debur and they work well.

### ⭐⭐⭐⭐ Works very well
*by P***L on July 18, 2024*

I used the smaller of the three (not sure when i will ever use the larger two, wish i could have purchased a smaller set of three for household uses) and drilled a pilot/through hole for the h/w i was going to use. Using a hand drill with adjustable collet, the chamfer tool worked perfectly. i needed to increase the screw diameter size, hence the chamfer diameter needed to increase slightly and i was able to resize w/o any difficulty. All told, the tool cuts nicely w/o chatter or wander and gave me the countersink i needed.
