Guhring 9007320057900 Solid Carbide Jobber Drill Bit

Product Description

The GUHRING 9007320057900 is a solid carbide jobber length drill bit designed for precision hole-making in non-ferrous and aluminum workpieces. This wire gauge number 1 bit measures 0.2280 inches in diameter and delivers consistent performance in general-purpose drilling applications. It features a 118-degree faceted point angle, a two-flute right-hand spiral configuration, and a web-thinned tip that reduces thrust and improves chip evacuation. The bright uncoated finish makes it well-suited for softer materials where coating adhesion or built-up edge is a concern. Licensed HVAC, mechanical, and industrial technicians rely on carbide construction for extended tool life in production environments.

This drill bit is built for use in CNC machining centers, drill presses, and hand-held drilling equipment where consistent hole diameter and finish are required. The straight-cylindrical shank at 0.2280 inches fits standard three-jaw chucks and collet-style tool holders. With a flute-to-diameter ratio of 5xD, the 9007320057900 handles moderate-depth holes efficiently. It is best applied in aluminum, non-ferrous metals, and similar materials designated under the N material group code. The Series 732 design follows DIN specification standards, which ensures dimensional interchangeability with other DIN-conforming tooling setups.

Key Features

• Solid carbide construction for extended tool life compared to HSS alternatives
• 118-degree faceted point angle with web-thinned tip reduces entry thrust and improves hole accuracy
• Two-flute right-hand spiral flute design promotes efficient chip evacuation
• Bright uncoated finish optimized for aluminum and non-ferrous workpiece materials
• Straight-cylindrical shank with h8 diameter tolerance ensures secure, consistent chuck seating
• Conforms to DIN specification standards for dimensional interchangeability

Compatibility

Designed as a general-purpose replacement or production-use drill bit for standard three-jaw chucks and collet holders accepting a 0.2280-inch straight-cylindrical shank. Intended for use with aluminum and primary N-group non-ferrous workpiece materials per Series 732 DIN specification.

Installation Notes

Install into a properly sized collet or three-jaw chuck and confirm shank is fully seated before operation. Ensure the drilling machine spindle speed and feed rate are set per the material and diameter recommendations for solid carbide tooling. Do not use this bit on hardened steels or materials outside its rated N-group material designation. Inspect the cutting edges and web prior to each use and replace if chipping or wear is observed.
