Precision Twist Drill 5998007 Jobber Drill Bit 3/32 in

Product Description

The PRECISION TWIST DRILL 5998007 is a jobber-length twist drill bit designed for general-purpose drilling in a wide range of materials. It measures 3/32 inch (0.0938 inch decimal) in diameter with an overall length of 2.25 inches and a flute length of 1.25 inches. The bit is manufactured from high speed steel with a steam oxide coating that reduces friction and provides basic corrosion resistance. The 135-degree split point reduces walking on entry and requires less feed pressure than a standard 118-degree point. A web-thinned, tapered web construction supports chip evacuation through the two spiral flutes. This bit is typically installed by machinists, maintenance technicians, HVAC and plumbing trade professionals, and electricians during sheet metal or structural drilling tasks.

The 5998007 is suited for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and other hard materials. The straight cylindrical shank seats in standard 3-jaw drill chucks on hand drills, drill presses, and CNC equipment. With a flute-to-diameter ratio of 13xD and a maximum drilling depth of 1.25 inches, it performs well in production and field repair applications where consistent hole quality in tough materials is required. It conforms to NAS 907 and ANSI standards, making it appropriate for aerospace and industrial work where specification compliance matters.

Key Features

• 135-degree split point reduces bit walking and lowers required feed pressure on hard materials
• Steam oxide coating minimizes friction and offers basic corrosion resistance
• Web-thinned, tapered web supports efficient chip evacuation through two spiral flutes
• High speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Straight cylindrical shank fits standard 3-jaw chuck equipment without adapters
• Meets NAS 907 and ANSI specifications for controlled dimensional tolerances

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard 3-jaw drill chuck accepting a 3/32 inch straight cylindrical shank, including hand drills, drill presses, and CNC drilling equipment. Rated for use in steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium workpieces per workpiece material codes P, M, K, N, and S.

Installation Notes

Secure the shank fully in the drill chuck and verify concentricity before drilling. Apply consistent feed pressure appropriate to the workpiece material — excessive force on small-diameter bits increases the risk of breakage. Use cutting fluid or coolant when drilling stainless steel, titanium, or superalloys to manage heat buildup, since this bit does not have coolant-through capability. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point shows signs of dulling to maintain hole quality and prevent workpiece damage.
