Precision Twist Drill 5998377 Jobber Drill Bit 34

Product Description

The PRECISION TWIST DRILL 5998377 is a jobber-length drill bit in wire gauge size 34, with a decimal diameter of 0.1110 inches. Ground from high-speed steel and finished with a steam oxide coating, it is designed for general-purpose production drilling in metal fabrication and maintenance applications. The 118-degree standard point geometry suits a broad range of workpiece materials. The bit measures 2.625 inches overall with a 1.5-inch spiral flute length and a straight-cylindrical shank. Licensed tradespeople in machining, mechanical, and HVAC-plumbing-electrical service trades rely on this bit size for close-tolerance hole work in ferrous and non-ferrous substrates.

This bit is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field environments. Its regular spiral flute and tapered web configuration with web thinning help clear chips efficiently during through-hole and blind-hole operations. The Series R18 designation places this bit in Precision Twist Drill's standard jobber lineup, appropriate for use in handheld drills, drill presses, and CNC equipment with a matching 0.1110-inch collet or chuck.

Installation Notes

Installation and use are performed by machinists, pipefitters, electricians, HVAC technicians, and general maintenance trades. Always secure the workpiece fully before drilling and confirm chuck or collet grip on the full shank diameter. Power down and de-energize any equipment being drilled into before beginning work. Follow applicable workplace safety standards for rotating cutting tools.
