Guhring 9007690040000 Solid Carbide Die Drill Bit

Product Description

The GUHRING 9007690040000 is a solid carbide straight-flute die drill bit designed for high-performance drilling in aluminum, aluminum alloy, and cast iron. It carries a 4.00 mm (0.1575 inch) cutting diameter with a 120-degree standard point angle and features internal coolant-through capability via a round coolant hole. The submicron carbide grade and web-thinned geometry support accurate, clean entry at depth. This bit is manufactured to DIN 6535HA shank standards and is suited for CNC machining centers and precision drilling operations where hole quality and tool life are critical. It ships uncoated and is ready for use as received.

This drill bit is built for metalworking applications involving aluminum and cast iron workpieces, including die and mold work, precision component manufacturing, and production machining. The 7xD flute-to-diameter ratio and right-hand cutting direction make it a practical choice for deep-hole operations where chip evacuation and coolant delivery are priorities. It is appropriate for shop environments running coolant-through tooling programs on CNC drilling and machining equipment.

Key Features

• Solid submicron carbide construction for extended tool life in aluminum and cast iron
• Internal coolant-through design with round coolant hole for effective chip evacuation at depth
• Web-thinned geometry reduces entry force and improves hole accuracy
• 120-degree standard point angle for clean, precise entry
• Straight-flute configuration suited to die drilling applications
• DIN 6535HA shank compliance for reliable machine-tool holding

Compatibility

Designed as an OEM-specification solid carbide die drill bit for use in CNC machining centers and drilling equipment accepting a 6.00 mm shank per DIN 6535HA. Primary workpiece materials are aluminum and aluminum alloy; secondary material compatibility includes cast iron.

Installation Notes

Installation and tool changes must be performed by a qualified machinist with the spindle fully stopped and machine power locked out per facility safety protocols. Ensure the toolholder collet or chuck is clean and undamaged before seating the 6.00 mm shank. Coolant-through connections should be verified and purged before the first cut. Follow the machine manufacturer and tooling recommendations for speeds, feeds, and maximum drilling depth to avoid tool breakage.
