KEO 55256 Cobalt Steel Machine Single-End Countersink, TiN Coated, 4 Flutes, 82 Degree Point Angle, Round Shank, 1/2" Shank Diameter, 5/8" Body Diameter

KEO 4-flute center countersinks are versatile tools designed for countersinking holes for centers or for enlarging existing holes. 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.
