Precision Twist Drill 5998419 7/32 Inch Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5998419 is a jobber-length twist drill bit designed for general-purpose hole-making in metal and other structural materials. It measures 7/32 inch (0.2188 inch) in diameter with an overall length of 3.75 inches and a spiral flute length of 2.5 inches. The bit is manufactured from high-speed steel with a bright, uncoated finish and features a standard 118-degree point angle. A tapered web with web thinning reduces thrust during entry and helps center the bit at the start of a cut. Licensed tradespeople in HVAC, plumbing, and electrical trades rely on bits like this for drilling mounting holes, conduit knockouts, and structural penetrations.

This drill bit is suited for right-hand, clockwise cutting in a wide range of workpiece materials including steel, cast iron, non-ferrous metals, superalloys, and titanium. Its straight cylindrical shank fits standard three-jaw drill chucks on corded drills, cordless drills, and drill presses. With a flute-to-diameter ratio of 11xD and a maximum drilling depth of 2.5 inches, it handles typical jobsite through-drilling tasks in sheet metal, light structural steel, and pipe fittings. It carries ANSI specification designation and falls within the R10H-R18H series.

Key Features

• High-speed steel construction for durability in metal drilling applications
• 118-degree standard point angle for accurate starting on flat and curved surfaces
• Web-thinned, tapered web design reduces drill thrust and improves chip evacuation
• Right-hand spiral flute pulls chips out of the hole during drilling
• Straight cylindrical shank fits standard drill chucks without adapters
• ANSI-compliant jobber length suitable for general-purpose trade use

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard three-jaw chuck accepting a 7/32 inch straight cylindrical shank. Suitable for use in steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces per manufacturer specifications.

Installation Notes

Install in a properly rated drill press, corded drill, or cordless drill with a chuck rated for the shank diameter before energizing the tool. Secure the workpiece firmly before drilling to prevent rotation or movement. Use cutting fluid or coolant when drilling harder alloys to extend bit life, though this bit does not support coolant-through delivery. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is present.
