Precision Twist Drill 6002731 Jobber Drill Bit 3/64 in

Product Description

The PRECISION TWIST DRILL 6002731 is a jobber-length drill bit designed for precision drilling in a wide range of materials. Built from solid carbide with a bright uncoated finish, it features a 3/64 inch (0.0469 inch decimal) diameter, a 118-degree standard point angle, and a right-hand spiral flute configuration. The overall length is 1.5 inches with a 3/4 inch flute length, making it well suited for shallow, accurate holes in tight spaces. The tapered web construction adds rigidity and helps maintain point stability during drilling operations. Machinists, tool-and-die technicians, and maintenance professionals working with small-diameter applications are the primary users of this bit.

This drill bit is rated for use in steel, stainless steel, cast iron, non-ferrous metals, and hard materials, covering material codes P, M, K, N, and H. It is a general-purpose tool appropriate for production machining, bench work, and maintenance drilling where a small-diameter, jobber-length bit is required. The straight cylindrical shank seats directly into standard drill chucks without adapters, and the 16xD flute-to-diameter ratio supports consistent chip evacuation in typical drilling depths up to 3/4 inch.

Key Features

• 3/64 inch (0.0469 inch) diameter with matching straight cylindrical shank for direct chuck mounting
• 118-degree standard point angle for accurate entry on flat and curved workpiece surfaces
• Solid carbide construction provides hardness and wear resistance across a broad material range
• Bright uncoated finish maintains as-ground geometry without coating buildup on small cutting edges
• 2-flute regular spiral design with tapered web promotes chip clearance in short drilling depths
• Conforms to ANSI standards, Series D33F

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with standard drill chucks accepting a 3/64 inch straight cylindrical shank. Rated for steel, stainless steel, cast iron, non-ferrous metals, and hard materials per material codes P, M, K, N, and H.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, CNC machining center, or hand-held power drill with an appropriate chuck. Secure the shank fully in the chuck jaws and verify concentricity before operation to avoid deflection at this small diameter. Do not exceed the rated maximum drilling depth of 3/4 inch without retracting to clear chips. Coolant-through is not supported on this bit; use a compatible cutting fluid applied externally when drilling hard or abrasive materials.
