Product used for counterboring knife handle rivet holes. Excellent value for the money.

The size is perfect for a socket cap screw, and very impressed at how sharp these bits are, it board the hole out very quickly with large chips leaving a clean hole. Tip, slow speed is your friend, ran the drill press at 300 RPM

The 5.2 is the size I needed the most, I was disappointed to find the wrong size bit in the 5.2 package.

I was in need of an affordable-cheap set of metric countersink endmills. These came through as advertised. I have only used the M4 so far, but it works great as seen in the attached pics.So happy I found an affordable set. All the pro's say expect to spend 1/2 as much as you spent on your mill buying the needed tools. There wrong imho. Expect to spend as much as your mill in tooling. I'm not talking about buying a Kurt vice either.Solid 4 star product. Nothing wrong with them.

The sizes can work for SAE or metric bolt and screw sizes. The metal the cutters are made from will not hold up machining steel.
