Guhring 9007680135000 Carbide Die Drill Bit 0.5315 in

Product Description

The GUHRING 9007680135000 is a solid carbide straight-flute die drill bit designed for high-performance drilling in aluminum and non-ferrous materials. Part of the Series 768 lineup, it features a 0.5315-inch (13.50 mm) cutting diameter with a 120-degree point angle and a web-thinned tip geometry that reduces entry force and improves chip evacuation. Internal coolant-through capability via round coolant holes allows higher feed rates and longer tool life in production environments. This bit is right-hand cutting, uncoated, and manufactured from submicron carbide grade stock. It is installed by machinists and tool-room professionals in CNC drilling and die-making applications.

This drill bit is suited for precision drilling operations in aluminum, aluminum alloy, and cast iron workpieces. The 4xD flute-to-diameter ratio and a maximum drilling depth of 2.116 inches (53.75 mm) make it appropriate for moderate-depth holes in production or job-shop settings. The 14.00 mm shank diameter and DIN 6535HA shank specification ensure compatibility with standard toolholders used in CNC machining centers and drill presses configured for precision die work.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in hard and abrasive materials
• Internal coolant-through design with round coolant holes supports high feed rates and chip flushing
• Web-thinned point reduces thrust force at entry and improves hole quality
• 120-degree standard point angle optimized for aluminum and cast iron drilling
• Right-hand cutting, 2-flute straight geometry for clean chip evacuation in die applications
• DIN 6535HA shank for secure retention in standard CNC toolholders

Compatibility

Designed for use in CNC machining centers and drill presses accepting a 14.00 mm DIN 6535HA straight shank. Primary workpiece materials are aluminum and aluminum alloy; secondary applications include cast iron per Series 768 specifications.

Installation Notes

Install and remove this tool only while the spindle is fully stopped and the machine is locked out per applicable safety procedures. Confirm the toolholder collet or chuck is rated for the 14.00 mm shank diameter before seating. Connect coolant-through supply lines before initiating a drilling cycle to prevent thermal damage to the carbide substrate. Tool grinding or regrinding should be performed only by personnel with carbide tooling experience using appropriate grinding equipment.
