Precision Twist Drill 5995829 Jobber Drill Bit Wire 30 Hss

Product Description

The PRECISION TWIST DRILL 5995829 is a jobber length drill bit designed for general-purpose drilling in demanding trade applications. Built from M2 high speed steel with a bronze/purple coating, it carries a wire gauge size of 30, which equals 0.1285 inches in decimal. The 135-degree split point reduces walking on entry and requires no center punch on most surfaces. With a right-hand spiral flute and web-thinned tip, this bit maintains cutting efficiency across a range of workpiece materials. It is installed by machinists, maintenance technicians, pipefitters, and sheet metal workers who need consistent performance in production or field drilling setups.

This bit is suited for drilling steel, stainless steel, cast iron, superalloys, and titanium — covering ISO material codes P, M, K, and S. The 2.75-inch overall length and 1.625-inch flute length make it appropriate for through-hole and moderate-depth drilling in tight clearances typical of mechanical assemblies, electrical enclosures, and fabrication work. The straight cylindrical shank seats directly in standard drill chucks and quick-change systems without adapters. It conforms to ANSI standards and falls within the HX10-HX15-HX18 series from Precision Twist Drill.

Key Features

• Wire size 30 (0.1285 inches) right-hand cut jobber length configuration
• 135-degree split point with web-thinned geometry reduces thrust and entry walking
• M2 high speed steel construction with bronze coating for heat and wear resistance
• Two spiral flutes with tapered web and regular spiral for chip evacuation
• Straight cylindrical shank fits standard drill chucks without adapters
• ANSI-compliant geometry; rated for steel, stainless, cast iron, superalloys, and titanium

Compatibility

Designed as a general-purpose OEM-style jobber length drill bit compatible with standard drill chucks accepting a 0.1285-inch straight cylindrical shank. Rated for use in steel, stainless steel, cast iron, superalloys, and titanium workpieces per ISO material designations P, M, K, and S.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard keyed or keyless drill chuck on a drill press, hand drill, or CNC spindle. Confirm the chuck is fully tightened and the shank is fully seated before operation. Use appropriate cutting fluid or coolant when drilling stainless steel, cast iron, or superalloys to extend bit life and prevent work hardening. Do not exceed the recommended 1.625-inch maximum drilling depth for this bit length.
