Cleveland C73460 Jobber Length Drill Bit Wire 32 Hss

Product Description

The CLEVELAND C73460 is a jobber-length drill bit designed for precision hole-making in metal, aluminum, and similar materials. It is manufactured from high-speed steel with a bright, uncoated finish and features a 118-degree split point with web thinning for reduced walking and lower thrust on entry. The straight-cylindrical shank measures 0.1160 inches in diameter, matching the wire size 32 nominal diameter of 0.1160 inches. With an overall length of 2.75 inches and a flute length of 1.625 inches, this bit fits standard drill chucks used by machinists, maintenance technicians, and fabricators working in production and job-shop environments.

The C73460 is suited for drilling aluminum as its primary workpiece material and is rated for general-purpose use across ferrous and non-ferrous stock. The two-flute spiral design with a regular helix and tapered web configuration promotes chip evacuation in through-hole and blind-hole applications. It conforms to NAS 907 Type A standards, making it appropriate for aerospace-adjacent and precision manufacturing work where dimensional tolerances and material specifications are controlled. No coolant-through capability is present, so flood or mist coolant applied externally is the standard approach for high-cycle drilling.

Key Features

• Wire size 32 with a decimal diameter of 0.1160 inches and a diameter tolerance of -0.0005 to 0.0000 inches
• 118-degree split point with web thinning reduces thrust and self-centers on entry
• High-speed steel construction rated as heavy-duty grade for extended tool life
• Bright, uncoated finish suitable for use with cutting fluids on aluminum and soft metals
• Meets NAS 907 Type A specification for controlled-tolerance jobber-length drill bits
• Two-flute regular-spiral design with tapered web promotes efficient chip clearing

Compatibility

Designed as an OEM-style replacement or direct procurement option for any application requiring a wire-gauge 32 jobber-length drill bit with a straight-cylindrical shank conforming to NAS 907 Type A standards.

Installation Notes

Install in a standard drill chuck or drill press with a properly sized collet for 0.1160-inch shanks. Secure the shank fully seated in the chuck before operation to prevent runout. Power down and lock out any machine tool before changing bits. Apply an appropriate cutting fluid externally when drilling aluminum or steel at production feed rates to manage heat and extend bit life.
