KEO 53513 Cobalt Steel Single-End Countersink, TiN Coated, 82 Degree Point Angle, Round Shank, 3/8\ Shank Diameter, 5/8\ Body Diameter
- 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.
