Cobra Carbide 2 flute N/C spotting general drill bit is manufactured from premium submicron level carbide grain. Ideal for chamfering or spot drilling. For centering and countersinking on NC and CNC Machines. 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. 90 degrees point angle. Tolerance: H6 - shank diameter; H7 - cut diameter.
