Guhring 9026010107200 Carbide Jobber Drill 27/64 in

Product Description

The GUHRING 9026010107200 is a solid carbide jobber-length drill bit designed for precision hole-making in demanding industrial and trade applications. Built from submicron-grade carbide with a bright coating, this bit delivers consistent performance where high hardness and edge retention are required. The 27/64 inch diameter and 130-degree point angle are suited for fast penetration with reduced thrust. A parabolic flute profile improves chip evacuation, which is especially important in deeper or interrupted cuts. The 5.375-inch overall length and 3.938-inch flute length follow standard jobber proportions, keeping the bit versatile across drill presses, CNC machining centers, and hand-held power tools.

This drill bit is intended for machinists, tool-and-die technicians, and precision fabricators working with ferrous and non-ferrous metals, composites, and hard plastics. The web-thinned, tapered web construction reduces the chisel edge load at the point, making it a reliable choice for production drilling where bit life and hole quality directly affect throughput. The straight-cylindrical shank seats securely in standard drill chucks and collets without modification. It is sold individually and conforms to ANSI specification designations, making it a drop-in fit within ANSI-standard tooling setups.

Key Features

• Submicron-grade solid carbide construction for extended edge life in hard materials
• 130-degree point angle reduces thrust and improves entry accuracy
• Parabolic flute geometry promotes efficient chip evacuation in deep holes
• Web-thinned tapered web minimizes chisel edge load at drill entry
• Bright coating finish — no added coating thickness to affect diameter tolerance
• Right-hand cut with straight-cylindrical shank fits standard chucks and collets

Compatibility

Designed for use in standard drill chucks and collets accepting a 27/64 inch straight-cylindrical shank. Conforms to ANSI specification designation for jobber-length drill bits in the 0.4000 to 0.5000 inch diameter range.

Installation Notes

Seat the shank fully and evenly in the chuck or collet before tightening to prevent runout. Solid carbide bits are brittle compared to high-speed steel — avoid side loading, flexing, or using in hand-held drills where alignment cannot be controlled. Always bring the spindle to a full stop before measuring or adjusting. Use appropriate speeds and feeds for the work material; carbide tolerates higher surface speeds than HSS but requires rigid setups to prevent fracture.
