Disston Company 119891 Hss Black Oxide Drill Bit 1/8 in 2 Pack

Product Description

The DISSTON COMPANY 119891 is a 2-pack of high speed steel (HSS) jobber-length drill bits with a black oxide finish, sized at 1/8 inch diameter by 2-3/4 inches in length. The 135-degree split point features four cutting edges that reduce walking on contact and drive fast penetration without a center punch. The black oxide tempering treatment lowers frictional resistance and promotes efficient chip evacuation. These bits are suited for electricians, plumbers, HVAC techs, and general tradespeople who need a reliable, economical bit for light-duty drilling tasks across a range of common materials.

These drill bits are recommended for use in wood, plastic, wallboard, plywood, soft metals, aluminum, brass, and bronze. They are also rated for occasional use in stainless steel and other hard metals. The straight shank and jobber-length profile fit standard 3-jaw drill chucks and most common corded and cordless drills used in trade and maintenance settings. The carded 2-pack format is convenient for tool storage and point-of-use access on job sites.
