Guhring 9007680050000 Carbide Drill Bit 5mm 120deg

Product Description

The GUHRING 9007680050000 is a straight-flute, solid carbide drill bit engineered for high-performance drilling in aluminum and non-ferrous materials. Built from submicron carbide with a bright uncoated finish, it delivers clean, accurate holes with a 120-degree standard point angle. The two-flute, right-hand cutting geometry is paired with internal coolant-through capability via a round coolant hole, making it well-suited for CNC machining centers where through-spindle coolant is available. Web-thinned construction reduces thrust load at entry. Diameter tolerance is held to +0.004 to +0.016 mm, supporting consistent hole quality in production environments.

This drill bit is sized at 5 mm (0.1969 inches) in diameter with a 6 mm shank that conforms to DIN 6535HA, the standard for cylindrical shanks with driving flat. The flute-to-diameter ratio is 4xD, with a maximum recommended drilling depth of 28.50 mm (1.122 inches). It is designed for use in machining operations targeting aluminum, aluminum alloys, and cast iron. Typical installers include CNC machinists and tool-and-die professionals working in production or job-shop environments.

Key Features

• Submicron solid carbide construction for extended tool life in non-ferrous and cast iron applications
• Coolant-through design with round coolant hole for effective chip evacuation and heat management
• 120-degree standard point angle with web-thinned geometry to reduce entry thrust
• DIN 6535HA-compliant 6 mm shank for secure toolholder engagement
• Right-hand, two-flute straight configuration for controlled chip flow in shallow-to-moderate depth holes
• Diameter tolerance of +0.004 to +0.016 mm for repeatable hole sizing

Compatibility

Designed for use in CNC machining centers and drill presses equipped with through-spindle coolant and toolholders accepting DIN 6535HA cylindrical shanks. Primary workpiece materials are aluminum and aluminum alloys; secondary compatibility includes cast iron (material codes K and N).

Installation Notes

Installation and operation should be performed by qualified machinists familiar with CNC tooling setup and speeds-and-feeds selection for carbide cutting tools. Verify spindle runout and toolholder clamping before operation, as carbide is brittle and sensitive to lateral loading. Confirm coolant pressure and flow are adequate before initiating through-coolant drilling cycles. Consult the machine tool manufacturer and GUHRING Series 768 application data for appropriate cutting parameters.
