Guhring 9007680085000 Carbide Die Drill Bit 0.3346 in

Product Description

The GUHRING 9007680085000 is a solid carbide straight-flute die drill bit engineered for high-performance drilling in non-ferrous and light alloy materials. Built to Series 768 standards and conforming to DIN 6535HA shank specification, this bit features a 120-degree point angle, web-thinned tip geometry, and through-coolant capability via a round coolant-hole configuration. The submicron carbide grade provides the edge retention needed for tight-tolerance production work. With an uncoated finish and a diameter tolerance of +0.006 to +0.021 mm, this drill is suited for applications demanding precise hole sizing in aluminum and similar materials. Licensed HVAC techs and machinists working in precision fabrication environments will recognize the quality indicators built into this tool.

This drill bit is designed primarily for cutting aluminum, aluminum alloys, and cast iron in production or job-shop environments where consistent hole quality and tool life are critical. The straight-flute design aids chip evacuation in deep-hole scenarios, and the 4xD flute-to-diameter ratio supports drilling depths up to 1.9000 inches (48.25 mm). Through-coolant delivery keeps cutting temperatures in check during high-cycle operations. It is equally applicable in CNC machining centers and manual drill press setups requiring a DIN-standard shank interface.

Key Features

• Solid submicron carbide construction for extended tool life in non-ferrous and cast materials
• 120-degree standard point angle with web-thinned tip for accurate entry and reduced thrust
• Through-coolant capable with round coolant-hole design to manage heat in high-cycle drilling
• Straight-flute geometry promotes efficient chip flow in aluminum and aluminum alloy workpieces
• DIN 6535HA shank specification ensures compatibility with standard toolholding systems
• Diameter tolerance of +0.006 to +0.021 mm supports close-tolerance hole requirements

Compatibility

Designed as an OEM-specification solid carbide die drill bit for use with standard DIN 6535HA-compliant toolholders; primary workpiece materials are aluminum, aluminum alloy, and cast iron as specified by material codes K and N.

Installation Notes

Installation and operation should be performed by qualified machinists or toolroom personnel familiar with carbide tooling. Ensure the machine spindle and toolholder are clean and within runout tolerance before seating the DIN 6535HA shank to prevent edge chipping. Activate through-coolant supply before engaging the cut to maintain proper chip evacuation and thermal control. Inspect the cutting edges before each use, as carbide tools are brittle and susceptible to damage from improper handling or interrupted cuts without appropriate feed and speed parameters.
