The chatter-free cutting action requires minimal power. The microsmooth CNC precision ground construction produces clean, smooth cutting without smearing on a variety of materials. The tool especially excels in countersinking or deburring holes in aluminum, plastics and other nonmetallics. Cobalt steel tools are similar to high-speed steel, but with more cobalt for improved performance when cutting harder metals such as stainless steel or nickel alloys. Titanium nitride coatings add a hard layer of gold-colored ceramic to the surface that extends tool life and permits faster cutting speeds than uncoated tools. Round shanks allow use with a wide variety of toolholding systems. When run in a counterclockwise direction (right-hand cut) spiral fluted tools evacuate chips up and out of the cut to reduce clogging. 82 degree angle.

This is the first countersink I have ever used that actually works well. The countersink holes this bit makes are round and smooth with no burrs around the rim. Great performance. All the other countersinks I have used jitter in the hole and leave burrs, do not make round holes, and just do a bad job. Either that or they are dull. Skip the cheapos, spend the money on this bit and you will be happy with the result.

Cuts very well when in perfect condition. My unit stopped cutting after just 3 countersinks in ordinary 1/4" mild steel with tap fluid. Unacceptable for something this expensive.

If you are chamfering with a hand drill or not so rigid drill press this is what you want. No chattering, supper smooth. Should have bought this type of chamfer a long time ago.

Product didn’t last but for 4 holes while trying to countersink holes in carbon fiber. Junk. Not even worth one star, but had to give one to submit review.

Excellent tool for the price. Actually cuts the metal , not just push it around. Especially good with material that work hardens easily. Good buy....
