Guhring 9007680105000 Straight-flute Drill Bit 10.50mm

Product Description

The GUHRING 9007680105000 is a straight-flute solid carbide drill bit engineered for precision hole-making in non-ferrous and ferrous materials. Built from submicron carbide with a bright, uncoated finish, this bit features a 120-degree point angle and web-thinned geometry that reduces thrust and improves centering at entry. With a 10.50 mm cutting diameter and a flute-to-diameter ratio of 4xD, it is suited for applications requiring consistent chip evacuation and tight diameter tolerance. A round coolant-through passage supports high-speed drilling in production environments where heat management is critical. Licensed machinists, toolroom technicians, and CNC operators are the primary users of this tooling.

This drill bit is designed for machining aluminum, aluminum alloy, and cast iron workpieces. The straight-flute design is well matched to through-hole and short-chip materials where flute packing is not a concern. The right-hand cutting direction and 2-flute configuration make it compatible with standard CNC machining centers, drill presses, and manual machines running conventional coolant systems. The Series 768 designation follows DIN 6535HA shank standards, making it a direct fit in toolholders and collet chucks dimensioned to that specification.

Key Features

• Straight-flute geometry optimized for aluminum, aluminum alloy, and cast iron
• Submicron solid carbide construction for wear resistance and dimensional stability
• 120-degree standard point with web-thinning to reduce entry thrust
• Coolant-through design with round coolant-hole shape for heat and chip management
• Diameter tolerance held to +0.007 to +0.025 mm for close-tolerance bore applications
• DIN 6535HA shank specification for broad toolholder compatibility

Compatibility

Designed for use in toolholders and collet chucks conforming to DIN 6535HA with a 12.00 mm shank diameter. Primary workpiece materials are aluminum, aluminum alloy, and cast iron.

Installation Notes

Installation and use should be performed by qualified machinists or CNC technicians familiar with carbide tooling. Ensure the machine spindle and toolholder are fully powered down and locked out before loading or unloading the bit. Verify collet or chuck bore matches the 12.00 mm shank diameter before tightening to prevent runout. Carbide tooling is brittle and should not be used in setups with excessive vibration or interrupted cuts beyond the material ratings for this series.
