Precision Twist Drill 5995807 No. 25 Hss Jobber Drill

Product Description

The PRECISION TWIST DRILL 5995807 is a wire-gauge No. 25 jobber-length drill bit designed for general-purpose and heavy-duty drilling applications. Manufactured from M2 high-speed steel with a straw (bronze) coating, it features a 135-degree split-point geometry with web thinning for reduced thrust and faster penetration. The two-flute regular spiral design promotes efficient chip evacuation. At 3 inches overall length with a 1.875-inch flute length, this bit suits standard drill chucks and handheld or bench-mounted drilling equipment. It is built to ANSI standards and is rated for use in high-temperature alloys and similar demanding workpiece materials.

This drill bit is intended for professional tradespeople and machinists drilling in high-temp alloys, stainless, cast iron, and non-ferrous metals — material grades classified under P, M, K, and S workpiece codes. The straight cylindrical shank with a 0.1406-inch shank diameter fits standard three-jaw drill chucks. The Series HX10-HX15-HX18 designation places this bit in a heavy-duty line suited for production and maintenance drilling scenarios where tool life and hole accuracy are priorities.

Key Features

• M2 high-speed steel construction for heat resistance and edge retention
• 135-degree split point with web thinning reduces walking and lowers required thrust
• Straw (bronze) coating provides mild lubricity and surface protection
• Regular spiral flute geometry promotes chip clearing in deep-hole drilling
• Straight cylindrical shank compatible with standard drill chucks
• Built to ANSI specification; rated for high-temp alloy workpiece materials

Compatibility

Designed as an OEM-style jobber drill bit for use in standard three-jaw drill chucks across handheld, bench-top, and column drill press platforms. Part of the PRECISION TWIST DRILL Series HX10-HX15-HX18 heavy-duty line.

Installation Notes

Installation is performed by machinists, maintenance technicians, or qualified tradespeople. Ensure the drill press or handheld drill is fully powered off and unplugged before changing bits. Secure the straight shank firmly in the chuck and verify concentricity before beginning a cut. Use appropriate cutting fluid for high-temp alloy materials to extend tool life and maintain hole tolerance.
