        			Cobra Carbide jobber regular length drill bit is manufactured from premium sub micron grain carbide. Precision ground carbide drills are designed for high feed rate and good chip evacuation. 118 degrees four facet point angle. Right hand cut and right hand spiral. 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. Tolerance: H6 - shank diameter; H7 - cut diameter. Excellent work on aluminum alloy, carbon steel and cast iron materials. H6 - shank diameter tolerance; H7 - drill diameter Tolerance.
