KEO 53128-01 Single Flute Countersink, High Speed Steel, 82 Degree Cutting Angle, 1/2" Body Diameter

I'm spoiled now. After using conventional countersinks all my life & having to resorts to all kinds of trickery to avoid a choppy looking hole, I now know about single flute countersinks. Beautiful, professional looking countersinks, in aluminum at least. I'll find out later in other materials.

Good price...cuts well...I will that a single flute everytime

Great tool. Quality build and cuts great with no chatter!

Great Item

Worked outstanding in aluminum.
