Precision Twist Drill 5995903 Wire 46 Hss Jobber Drill Bit

Product Description

The PRECISION TWIST DRILL 5995903 is a wire gauge size 46 jobber-length drill bit designed for general-purpose drilling in steel, stainless steel, cast iron, superalloys, and titanium. The bit is manufactured from high speed steel with a bronze coating and features a 135-degree split point with web thinning for faster penetration and reduced walking on hard surfaces. At 2.125 inches overall length with a 1.125-inch spiral flute, this is a compact, precision-ground bit suited for production drilling, maintenance work, and fabrication tasks where tight hole tolerances in small diameters are required. Licensed trade professionals and machinists are the primary users of this bit.

This bit is well suited for drilling small-diameter holes in ferrous metals and high-strength alloys in both shop and field environments. The 0.0810-inch decimal diameter makes it a practical choice for tapping pilot holes, instrument panel work, sheet metal applications, and precision assemblies where wire gauge sizing is specified. Its straight cylindrical shank fits standard drill chucks without adapters. The Series HX10-HX15-HX18 designation places it within PRECISION TWIST DRILL's general-purpose HSS bronze-coated jobber line.

Key Features

• Wire gauge size 46 (0.0810 inch decimal) for precise small-diameter drilling
• 135-degree split point with web thinning reduces thrust and minimizes bit walking
• High speed steel construction with bronze coating for improved lubricity and heat resistance
• Regular spiral, 2-flute design with tapered web for efficient chip evacuation
• Rated for steel, stainless steel, cast iron, superalloys, and titanium (ISO material codes P, M, K, S)
• Meets ANSI standards; straight cylindrical shank fits standard chucks

Compatibility

Designed as an OEM-style general-purpose jobber drill bit for use in standard drill chucks accepting a 0.0810-inch straight cylindrical shank, compatible with benchtop drill presses, hand drills, and CNC drilling applications within the Series HX10-HX15-HX18 product line.

Installation Notes

Installation and use of this bit is performed by machinists, maintenance technicians, HVAC fabricators, electricians, or plumbers during metal drilling operations. Secure the straight cylindrical shank firmly in the chuck before use and verify the workpiece is clamped to prevent rotation. Use appropriate cutting fluid or lubricant when drilling stainless steel, cast iron, or titanium to extend bit life and maintain hole quality. Do not exceed the maximum drilling depth of 1.125 inches without clearing chips.
