Accupro 10371 Jobber Drill Bit 13/64 Inch Solid Carbide

Product Description

The ACCUPRO 10371 is a solid carbide jobber length drill bit designed for precision hole-making in demanding machining applications. Built from solid carbide throughout, it delivers the rigidity and wear resistance needed when drilling hard or abrasive materials where high-speed steel tooling falls short. The bit measures 13/64 inch (0.2031 inch decimal) in diameter with a 3-inch overall length and a 1-1/4-inch spiral flute length. The 150-degree drill point angle and three-flute spiral configuration support efficient chip evacuation and accurate entry geometry. This is a right-hand cutting tool intended for use by machinists, tool-and-die tradespeople, and precision fabricators working on CNC or manual drill press setups.

This drill bit suits production and job-shop environments where tight tolerances and consistent hole quality are required. The straight cylindrical shank fits standard drill chucks and collets without modification. With a 5xD flute-to-diameter ratio, it handles moderate-depth holes in a single pass and is well-suited for ferrous and non-ferrous metals, composite materials, and other substrates that benefit from carbide tooling. It conforms to ANSI specification designation standards for jobber length drills. The bright uncoated finish makes it a straightforward, general-purpose carbide option without specialized surface treatment requirements.

Key Features

• Solid carbide construction for superior hardness and wear resistance compared to HSS
• 150-degree drill point angle for reduced thrust and accurate self-centering on entry
• Three-flute spiral design promotes efficient chip evacuation during drilling
• 1-1/4-inch flute length with 5xD flute-by-diameter ratio for moderate-depth holes
• Straight cylindrical shank compatible with standard drill chucks and collets
• Bright uncoated finish — no coating degradation concerns during regrinding or inspection

Compatibility

Designed as an OEM-style replacement or standard production drill bit for use in any setup accepting a straight cylindrical shank drill in the 0.2000 to 0.2500 inch diameter range, conforming to ANSI jobber length standards.

Installation Notes

Installation of this drill bit is performed by machinists or tooling technicians setting up CNC machining centers, manual drill presses, or hand-drill fixtures. Always power down and lock out the spindle drive before changing tooling. Ensure the shank is fully seated and the chuck or collet is torqued or tightened to the machine manufacturer's specification. Solid carbide tooling is brittle compared to high-speed steel — avoid lateral loading, interrupted cuts beyond the tool's rated capacity, or dropping the bit on hard surfaces.
