KEO 17431 Cobalt Steel Type B Combined Drill and Countersink, Uncoated (Bright) Finish, 60 Degree Point Angle, Round Shank, 31.50mm Body Diameter, 10.00mm Point Diameter

KEO metric type B combined drill and countersinks provide the same advantages as KEO standard bell type combined drill and countersinks but are available in standard metric sizes according to DIN333 specifications. 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. 60 degree angle. 21.20mm Bell diameter.
