Guhring 9007680090000 Straight-flute Drill Bit 9mm Carbide

Product Description

The GUHRING 9007680090000 is a straight-flute solid carbide drill bit engineered for high-performance drilling in aluminum and non-ferrous materials. Part of the Series 768 line, it features a 9.00 mm cutting diameter, a 120-degree standard point angle, and a bright/uncoated finish. The submicron carbide grade provides edge stability and wear resistance at elevated cutting speeds. Two flutes with web thinning reduce thrust forces and improve chip evacuation in shallow-to-moderate depth applications. Coolant-through capability via round coolant holes supports internal flushing to manage heat and extend tool life. A licensed machinist or tooling technician would typically deploy this bit on CNC machining centers or drilling fixtures in production environments.

This drill bit is suited for drilling aluminum, aluminum alloys, and cast iron in both production and job-shop settings. The 4xD flute-to-diameter ratio supports a maximum drilling depth of 47.50 mm. The 10.00 mm shank diameter conforms to DIN 6535HA, making it compatible with standard collet chucks and hydraulic tool holders configured for that shank size. It is appropriate for applications requiring consistent diameter tolerance within plus 0.006 to plus 0.021 mm and right-hand cutting direction.

Key Features

• Straight-flute geometry optimized for aluminum and aluminum alloys (material grade code K, N)
• Submicron solid carbide construction for edge stability and long tool life
• Web-thinned point reduces thrust and improves entry accuracy
• Coolant-through design with round coolant holes for internal chip flushing
• Diameter tolerance held to plus 0.006 to plus 0.021 mm for consistent fit
• DIN 6535HA shank specification for broad toolholder compatibility

Compatibility

Designed for use with toolholders conforming to DIN 6535HA with a 10.00 mm shank bore. Primary workpiece materials are aluminum and aluminum alloys; secondary materials include cast iron. Compatible with CNC machining centers and drilling units capable of supplying coolant through the spindle.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle and coolant supply are fully de-energized and locked out before changing tooling. Seat the shank fully into a clean, undamaged collet or toolholder and torque the retention mechanism to the toolholder manufacturer specification. Verify coolant-through passages are clear and that the machine controller is configured for right-hand cutting rotation before initiating a cycle.
