Disston Company 119883 Hss Black Oxide Drill Bit 7/64 in 2 Pack

Product Description

The DISSTON COMPANY 119883 is a high speed steel (HSS) black oxide drill bit sold in a 2-pack, sized at 7/64 inch diameter with a jobber length of approximately 2-5/8 inches. The 135-degree split point features four cutting edges that prevent walking on contact and deliver fast, clean penetration without a center punch. Black oxide tempering reduces frictional heat during cutting and promotes smooth chip evacuation. This bit uses a straight shank for standard 3-jaw chuck compatibility. It is suited for general-purpose drilling tasks and is installed by electricians, plumbers, HVAC techs, and maintenance professionals who need a reliable general-use bit for everyday jobsite work.

The 119883 is designed for drilling into wood, plastic, wallboard, plywood, soft metals including aluminum, brass, and bronze. It can also be used occasionally in stainless steel and other hard metals where a dedicated cobalt or carbide bit is not available. Its compact jobber length makes it practical for tight-clearance drilling in framing, panel boxes, and mechanical chases. The 2-pack format suits field technicians who keep spares on hand for high-cycle tasks.

Key Features

• 135-degree split point with four cutting edges eliminates walking and reduces the need for a center punch

Compatibility

Designed for use in standard straight-shank drill chucks; recommended for wood, plastic, wallboard, plywood, soft metals such as aluminum, brass, and bronze, with occasional use in stainless steel and other hard metals.

Installation Notes

Insert the straight shank fully into a 3-jaw chuck and tighten securely before use. Confirm drill speed is appropriate for the material being drilled — lower speeds are generally recommended for harder metals to extend bit life. Wear appropriate eye protection when drilling. Inspect the cutting edges before each use and replace bits that show signs of heat discoloration or chipping.
