As a rule, the more edges per revolution, the greater amount of material that may be removed. We have designed the 6-flute tools with staggered cutting edges. Solid carbide tools offer long tool life and faster cutting speeds than other substrates, but are more brittle and must be used with rigid toolholding systems. 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.

I’ve tried 3 times with these and every time they just chatter and bite too much.I purchased one a few months ago and it was great. I am cutting titanium and zirconium in high pressure cooling fluid. I’ve choked up as close as I can to the end of the bit to try and reduce the chatter but it’s real bad. I even tried brass and plastic. Brass it made chatter and it just chewed the plastic up. Seems like the cutters are not evenly ground or the relief angle is too sharp on these. Either way it’s my last. I’m going back to my old source and will gladly pay more.
