Guhring 9007320066300 Jobber Drill Bit Letter G Carbide

Product Description

The GUHRING 9007320066300 is a jobber length drill bit in Letter G size (0.2610 inches) machined from solid carbide. It operates on a standard 118-degree faceted point angle with a regular spiral flute and web-thinned geometry, reducing entry resistance and improving chip evacuation. The straight-cylindrical shank measures 6.63 mm in diameter with a shank length of 38 mm. Overall length is 101 mm with a flute length of 63 mm and a maximum drilling depth of 53.06 mm. The bright uncoated finish suits general-purpose drilling where coating adhesion to the workpiece is a concern. This bit belongs to GUHRING Series 732 and is sized to an h8 diameter tolerance for consistent, repeatable hole quality.

This drill bit is rated for general-purpose use with a primary workpiece material designation of N, which corresponds to non-ferrous metals including aluminum and similar soft, non-abrasive materials. It is a right-hand cut, two-flute design with a 5xD flute-to-diameter ratio, making it well suited for through-hole and blind-hole drilling operations in machine shop, maintenance, and production environments. The solid carbide construction gives it an advantage over high-speed steel in applications requiring tighter tolerances and longer tool life at higher spindle speeds.

Key Features

• Letter G size: 0.2610 inches, h8 diameter tolerance for precision fitment
• Solid carbide construction for extended tool life in non-ferrous materials
• 118-degree faceted point with web thinning for reduced thrust and cleaner entry
• Regular spiral, two-flute design promotes efficient chip removal
• Bright uncoated finish suitable for aluminum and other non-ferrous workpieces
• Straight-cylindrical shank compatible with standard drill chucks and collets

Compatibility

Designed as a general-purpose jobber length drill bit compatible with standard drill chucks and collet systems accepting a 6.63 mm straight-cylindrical shank, conforming to DIN specification.

Installation Notes

This drill bit is intended for use by machinists and tooling professionals in CNC machining centers, drill presses, or hand-held power tools with appropriate chuck capacity. Before changing tooling, ensure the spindle is fully stopped and the machine is powered down or locked out per OSHA lockout/tagout procedures. Secure the shank firmly in the chuck or collet to the manufacturer-specified clamping range to prevent runout. Do not exceed the maximum drilling depth of 53.06 mm in a single pass without retracting to clear chips.
