Guhring 9007680075000 Carbide Drill Bit 0.2953 in

Product Description

The GUHRING 9007680075000 is a straight-flute solid carbide drill bit engineered for high-performance drilling in non-ferrous metals and cast materials. Built from submicron carbide with a bright finish, this Series 768 drill delivers consistent accuracy and extended tool life in demanding production environments. The 0.2953 inch (7.50 mm) diameter bit features a 120-degree point angle, web-thinned geometry, and through-coolant capability via a round coolant hole, making it well-suited for automated machining centers and CNC applications. Licensed machinists and tooling professionals install and manage this type of cutting tool in precision manufacturing settings.

This drill bit is designed for machining aluminum, aluminum alloys, and cast iron. The straight-flute configuration supports clean chip evacuation in these materials, reducing heat buildup and maintaining bore quality. The through-coolant design allows direct coolant delivery to the cutting edge, which is especially valuable in high-speed or deep-hole drilling operations. At a 4xD flute-to-diameter ratio with an overall length of 91.00 mm, this bit fits standard toolholders conforming to DIN 6535HA shank specifications.

Key Features

• Submicron solid carbide construction for extended tool life and edge retention
• Through-coolant with round coolant-hole geometry for direct cutting-edge cooling
• Web-thinned point reduces entry force and improves centering accuracy
• 120-degree standard point angle suited to aluminum and cast iron drilling
• Right-hand cutting direction compatible with standard CNC spindle rotation
• Bright finish with no coating to maintain tight dimensional tolerances

Compatibility

Designed for use in CNC machining centers and drill presses with DIN 6535HA-compliant toolholders. Primary workpiece materials are aluminum, aluminum alloys, and cast iron.

Installation Notes

This tool should be installed by a qualified machinist or tooling technician. Secure the shank fully in a DIN 6535HA-compatible collet or chuck and verify runout before production use. Enable through-spindle coolant before initiating the cut when coolant-through capability is used. Do not exceed the recommended feed and speed parameters for the workpiece material to avoid tool breakage.
