Guhring 9007680067500 Die Drill Bit 17/64 in Carbide

Product Description

The GUHRING 9007680067500 is a straight-flute die drill bit engineered for high-performance drilling in aluminum and non-ferrous materials. Built from submicron-grade solid carbide, this bit delivers the rigidity and edge retention required for precision hole-making in demanding production environments. It measures 17/64 inch (0.2656 inch decimal, 6.75 mm) in diameter with a 120-degree drill point angle and a web-thinned tip geometry that reduces thrust and improves centering at entry. Internal coolant-through capability with a round coolant-hole shape supports chip evacuation and thermal management during deep-hole operations. Licensed trades and production machinists rely on this tool for consistent, tight-tolerance results.

This drill bit is designed for use in CNC machining centers, drilling machines, and production environments where aluminum, aluminum alloy, and cast iron workpieces are common. The 4xD flute-to-diameter ratio allows drilling to a maximum depth of 1.688 inches (42.88 mm), making it well suited for die work, fixture boring, and component drilling in light-metal fabrication. The right-hand cutting direction and two-flute configuration optimize chip flow in ductile materials. It conforms to DIN 6535HA shank specifications, making it compatible with standard HA-type collet chucks and tool holders.

Key Features

• Submicron-grade solid carbide construction for extended tool life and edge retention
• Straight-flute geometry optimized for aluminum and aluminum alloy drilling
• Web-thinned tip reduces axial thrust and improves self-centering at entry
• Coolant-through design with round coolant holes supports chip evacuation and heat control
• 4xD maximum drilling depth (1.688 inches / 42.88 mm) in a compact 91 mm overall length
• DIN 6535HA shank specification for use with standard HA collet systems

Compatibility

Designed for use in HA-type collet chuck tool holders conforming to DIN 6535HA. Primary workpiece materials are aluminum and aluminum alloys (material code K, N); secondary workpiece material compatibility includes cast iron.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Confirm coolant-through supply pressure and flow rate are appropriate for the material and feed rate before beginning the drilling cycle. Do not exceed the rated maximum drilling depth of 1.688 inches without retracting to clear chips.
