Precision Twist Drill 5998081 Jobber Drill Bit 32 Hss

Product Description

The PRECISION TWIST DRILL 5998081 is a jobber-length drill bit in wire gauge size 32, equivalent to 0.1160 inches in diameter. Manufactured from high speed steel with a bright uncoated finish, this bit features a standard 118-degree split-point angle and a two-flute spiral configuration with web thinning for improved chip evacuation and reduced walking on entry. The straight-cylindrical shank measures 0.1160 inches in diameter, making it compatible with standard drill chucks. Designed for general-purpose drilling in production and maintenance applications, it is installed by machinists, pipefitters, electricians, and general trade professionals who require precise hole sizing in a range of base materials.

This bit is suited for drilling steel, cast iron, non-ferrous metals, superalloys, and titanium in both shop and field environments. The R10H-R18H series designation places it within a standardized range of jobber-length HSS bits commonly used for through-hole and blind-hole work on structural components, enclosures, and mechanical assemblies. The 1.625-inch flute length supports drilling to a maximum depth of 1.625 inches per pass, appropriate for standard material thicknesses encountered in general fabrication and mechanical service work.

Key Features

• Wire gauge size 32, 0.1160-inch diameter with matching straight-cylindrical shank
• High speed steel construction for durability across steel, cast iron, non-ferrous metals, superalloys, and titanium
• 118-degree standard point angle with web-thinned tip for reduced entry thrust
• Two-flute regular spiral design promotes efficient chip removal
• Bright uncoated finish suitable for general-purpose use without coolant-through requirement
• ANSI-compliant specification for dimensional consistency

Compatibility

Designed as a general-purpose jobber-length replacement bit within the PRECISION TWIST DRILL R10H-R18H series, suitable for use with any standard drill chuck or driver accepting a 0.1160-inch straight-cylindrical shank. Primary workpiece material codes P, K, N, and S cover steel, cast iron, non-ferrous metals, superalloys, and titanium.

Installation Notes

Installation and use of this drill bit should be performed by qualified trade or machine shop personnel. Secure the straight-cylindrical shank firmly in a keyed or keyless chuck and verify runout before drilling. Power down and lock out the drilling machine before changing bits. Do not exceed the recommended flute depth of 1.625 inches per pass to avoid chip packing and bit deflection.
