Precision Twist Drill 5998672 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5998672 is a high-speed steel jobber-series drill bit built for drilling into hard surfaces where heat and mechanical stress are constant factors. With a tip diameter of 0.125 inches and a depth of cut reaching 4 inches, this bit is sized for standard through-hole and deep-reach applications in metal, hardened alloys, and similar materials. The HSS construction maintains cutting edge integrity under elevated temperatures, making it a dependable choice for trade and industrial use. Electricians, HVAC technicians, and general contractors rely on jobber-series bits for conduit knock-outs, sheet metal work, and structural drilling tasks.

The 4-inch depth of cut allows work through thicker stock or stacked materials without requiring extensions. It fits standard 3-jaw chucks and is compatible with corded drills, drill presses, and right-angle drill adapters commonly found in the trade environment.
