25/64" Black & Gold Jobber length Drill Bit

25/64" Black and Gold Jobber length drill bit type 190-AG, used for parallel linkage flange bushing kits. Our black and gold jobber length drill bits are a general purpose drill bit made from premium hi-molybdenum steel for high strength and have a 135* split point for sinking into hard materials without the drill bit "walking". The black and gold coating provides some lubricity for easier cutting and they are heat treated by nitro-carburizing for added strength. Excellent for drilling hardened steels and stainless steel. Made in the USA by Norseman Drill and Tool.
