31504 Micro Grain Solid Carbide Combined Drill Bit and Countersink, Uncoated (Bright) Finish, Round Shank, Spiral Flute, 60 Degrees Point, #00 Size, 1-1/4" Length (Pack of 1)

Cobra Carbide regular length combined drill bit and countersink is manufactured from premium submicron level carbide grain. Ideal for chamfering. 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. 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 degrees point angle. Tolerance: H6 - shank diameter; H7 - cut diameter.
