Numbered Drill Bits

Our Numbered Jobber length drill come in two materials: Black & Gold and Bright. The black & gold are made from high-molybdenum steel for high strength and the coating provides some lubricity for easier cutting and they are heat treated by nitro-carburizing for added strength. They feature a 135* split-point for sinking into hard metals without the drill bit "walking". Excellent for drilling hardened steels and stainless steel. Bright drill bits are made from general purpose steel and feature a 118* point while the Bright coating provides some lubricity for easier cutting. They are used for drilling non-ferrous metals, wood, and plastic. Made in the USA by Norseman Drill & Tool.
