Hertel 83246108 Carbide Jobber Drill Bit No. 63

Product Description

The HERTEL 83246108 is a solid carbide jobber-length drill bit sized to wire gauge No. 63, equivalent to 0.0370 inches in diameter. It is designed for precision drilling in small-diameter applications where consistent hole geometry and tight tolerances are required. The bit features a standard 118-degree point angle, a web-thinned tapered web for reduced thrust, and a bright finish with no coating. Overall length is 1.25 inches, with a flute length of 0.625 inches. The straight-cylindrical shank matches the bit diameter at 0.0370 inches. Diameter tolerance is held to -0.0005 to 0.0000 inches for close-tolerance work. It is suited for machinists, tool-and-die technicians, and precision fabricators working with small-bore applications.

This bit is rated for general-purpose use across a range of materials appropriate to the C2 carbide grade. Typical applications include drilling in ferrous and non-ferrous metals, plastics, and composites where a No. 63 wire-size hole is required. The right-hand spiral flute and web-thinned point aid chip evacuation and reduce walking on entry. It is sold as a single bit and is well-suited for benchtop drill presses, CNC machines, and precision hand drilling setups. No coolant-through capability is present, so external coolant or cutting fluid should be applied as needed based on workpiece material.

Key Features

• Solid carbide construction with C2 material grade for hardness and wear resistance
• No. 63 wire size, 0.0370-inch diameter with tight tolerance of -0.0005 to 0.0000 inches
• 118-degree standard point angle with web-thinned, tapered web for reduced entry thrust
• Bright finish, no coating — allows direct inspection of tool wear
• Right-hand cut with regular spiral flute for efficient chip removal
• Straight-cylindrical shank for use in standard collets and drill chucks

Compatibility

Designed as a general-purpose jobber-length drill bit for use in any machine tool or drill press accepting a straight-cylindrical shank at 0.0370 inches in diameter, including CNC machining centers, benchtop drill presses, and precision drilling fixtures.

Installation Notes

Installation and use of this bit should be performed by qualified machinists or tooling technicians. Ensure the drill chuck or collet is fully secured and rated for the shank diameter before operation. Power down the machine completely before inserting or removing the bit. Carbide tooling is brittle — avoid side loading, interrupted cuts without appropriate feed rates, or dropping the bit, as chipping or fracture can result.
