Precision Twist Drill 5998498 1/16 Inch Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5998498 is a jobber-length drill bit designed for general-purpose drilling in a wide range of materials. It measures 1/16 inch (0.0625 inches) in diameter with an overall length of 1.875 inches and a flute length of 0.875 inches. The bit is manufactured from high speed steel with a bright uncoated finish, giving it solid performance across standard drilling tasks. The 118-degree standard point angle and web-thinned, tapered web configuration reduce entry force and help center the bit on the workpiece. A spiral flute with a regular helix and right-hand cut evacuates chips efficiently during through and blind-hole drilling. This bit is installed and used by machinists, maintenance technicians, HVAC techs, plumbers, and electricians who need a reliable small-diameter bit for everyday drilling work.

The 5998498 is suited for drilling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. Its 1/16-inch straight-cylindrical shank fits standard drill chucks across benchtop drill presses, hand drills, and drill-driver setups. The 14xD flute-to-diameter ratio supports drilling to the full flute depth of 0.875 inches. This bit is a practical choice for light-duty metal drilling, sheet metal work, pilot holes, and general maintenance applications encountered in the trade.

Installation Notes

A licensed or qualified tradesperson should secure the shank fully in the drill chuck before use and verify chuck tightness. Always wear appropriate eye protection when drilling metal. For drilling hard materials such as stainless steel or cast iron, use cutting fluid to extend bit life and reduce heat buildup. Inspect the bit for wear or chipping before each use, and replace if the cutting edges show damage to prevent workpiece damage or bit breakage.
