KEO 55772 Solid Carbide Single-End Countersink, Uncoated (Bright) Finish, 3 Flutes, 100 Degree Point Angle, Round Shank, 1/4" Shank Diameter, 1/4" Body Diameter

For the carbide family of these tools, the three-flute represents the ideal "general purpose" countersink. They have enough chip clearance in the three-flute design for a variety of ferrous and non-ferrous materials, while providing enough strength with the radial relief design to attack hardened materials up to 40Rc. 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. 100 degree angle.
