Guhring 9007680032000 Carbide Die Drill Bit 0.126 in

Product Description

The GUHRING 9007680032000 is a solid carbide, straight-flute die drill bit designed for high-precision drilling applications in non-ferrous metals and cast iron. Built to Series 768 specifications, this uncoated submicron carbide tool features a 0.1260-inch (3.20 mm) cutting diameter, a 120-degree standard point angle, and a web-thinned tip geometry that reduces entry force and improves chip evacuation. The right-hand cutting direction and two-flute configuration make it well suited for tight-tolerance hole work where finish and dimensional accuracy are critical. Internal coolant-through capability supports higher feed rates and extended tool life in production environments.

This die drill bit is intended for use in machining operations on aluminum, aluminum alloys, and cast iron workpieces. Its high-performance submicron carbide substrate and web-thinned point are particularly effective in die and mold work, fixture machining, and precision component manufacturing where small-diameter, straight-flute drills are required. The 4xD maximum drilling depth ratio supports holes up to 0.7560 inches (19.20 mm) deep without the need for peck cycles in many setups. It is installed in CNC machining centers, drill presses, or precision manual equipment by machinists, tool-and-die makers, and production drilling technicians.

Key Features

• Solid submicron carbide construction for rigidity and wear resistance in non-ferrous and cast iron applications
• Web-thinned 120-degree standard point reduces thrust force and improves centering accuracy
• Coolant-through design supports chip flushing and heat management at depth
• Straight-flute geometry engineered for die and mold drilling where flute space is restricted
• Two-flute right-hand cutting configuration with 4xD depth capability up to 0.7560 inches
• Diameter tolerance of +0.004 to +0.016 mm ensures consistent hole sizing across production runs

Compatibility

Designed as a straight-flute solid carbide die drill bit for use in aluminum, aluminum alloys, and cast iron workpieces per the primary and secondary workpiece material designations K and N. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation and use should be performed by qualified machinists or tool-and-die technicians familiar with small-diameter carbide tooling. Ensure the spindle and collet or chuck are clean and properly torqued before seating the 6.00 mm shank to prevent runout that can fracture carbide drills at this diameter. Disengage spindle power and allow the machine to come to a complete stop before changing or inspecting the tool. When using the coolant-through feature, verify that coolant pressure and flow rate are compatible with the spindle and tool holder to avoid thermal shock to the carbide substrate.
