KEO ZErO flute countersink and deburring tools are simple, all-purpose tools made of Cobalt that provide flawless countersinking and deburring. 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. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. 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.

Easy to control very smooth cut. This is the best counter sink only bit I’ve ever used.
I’m a woodworker and needed a countersink for a 1/2” screw head and none of my standard drill-bit countersink combo but were large enough for the 1/2” head. I had a more conventional countersink only bit but it left a lot of chatter on the surface of the cut that looked terrible. This bit was the ticket in hard maple, worked quickly and very smooth and easy to control. Highly recommended.
Scritto da: Love it. Best I’ve seen.

Quality tool but shavings do not clear easily.
This tool works great. It cut nice and clean on walnut. It is well made and looks the part. My only minor gripe is that the shavings always end up in the hole in the middle. After a few holes I have to use something to push them out.

Wow. Beautiful
I have used this in plywood and hardwood (walnut) so far. It makes gorgeous, clean countersinks in pre-drilled holes. I literally said "Wow" out loud to nobody the first time I used it in plywood. I am never going back to those awful multi-fluted countersink bits that leave torn-up jagged edges!

Great countersync for threaded inserts
I bought this to counter sink the holes I was drilling for threaded inserts. When I first opened it, I wasn't expecting much, but it did great against red oak. Would purchase again.

If You Work With Aluminum, This Is What You Want
The single flute design keeps it from hopping all over the place like multi-flute versions. This makes for an excellent finish with no chatter marks. Just buy it.

So convenient and effective
I bought this to counter sink screws in a diy closet cabinet build, and I love this thing. I was skeptical of the design at first, but this thing works better than any other countersink I own. Even in situations where I use a different countersink, I give a light pass over the hole with this one to smooth it out or remove burrs. I will never again not own one of these.
