Guhring 9006520075000 Jobber Drill Bit 7.5mm Hss Tin

Product Description

The GUHRING 9006520075000 is a jobber-length twist drill bit ground from high speed steel and finished with a titanium nitride (TiN) coating. It carries a 7.5 mm (0.2953 inch) diameter with a 130-degree split point and a parabolic flute profile that evacuates chips aggressively during through-hole and deep-hole operations. Overall length is 4-19/64 inches (109 mm) with a flute length of 2-23/32 inches (69.06 mm). The straight-cylindrical shank seats directly in standard drill chucks without adapters. This bit is built to DIN 338 specification and suits production and maintenance drilling environments where consistent dimensional accuracy is required.

This drill is rated for aluminum and non-ferrous metals as its primary workpiece material, with material codes K, N, and P covering cast aluminum alloys, non-ferrous metals, and general steels respectively. The parabolic flute geometry and web-thinned, tapered web reduce thrust load at the tip, making it suitable for CNC machining centers, drill presses, and hand-held electric drills in light fabrication and sheet-metal work. Maximum recommended drilling depth is 2.274 inches (57.75 mm), which aligns with standard 5xD depth guidelines for this diameter class.

Key Features

• 7.5 mm diameter with a tight tolerance of -0.022 to 0.000 mm for precise hole sizing
• TiN coating extends surface hardness and reduces built-up edge on non-ferrous materials
• 130-degree point angle with web thinning lowers entry thrust and self-centers on most surfaces
• Parabolic flute geometry improves chip evacuation at higher feed rates
• DIN 338 specification ensures dimensional interchangeability with standard toolholders
• Straight-cylindrical shank fits standard drill chucks without bushings or adapters

Compatibility

Designed as a DIN 338 jobber-length drill bit compatible with any standard drill chuck accepting a 0.2953-inch straight-cylindrical shank, including CNC machining centers, drill presses, and hand-held electric drills within the 7.00 mm to 8.00 mm drill diameter range.

Installation Notes

This drill bit is installed and removed by a qualified machinist or maintenance technician using a standard keyed or keyless chuck. Secure the shank fully within the chuck jaws before starting the spindle. Always bring the spindle to a complete stop before changing tooling or clearing chips. Follow applicable shop safety standards and machine manufacturer guidelines for speed and feed selection based on workpiece material.
