Guhring 9064010011500 Micro Drill Bit 1.15mm Carbide

Product Description

The GUHRING 9064010011500 is a solid carbide micro drill bit engineered for precision drilling in demanding materials. Measuring 1.15 mm in diameter with a 140-degree faceted point, this bit delivers accurate entry geometry and reduced thrust force at small diameters. The TiAlN coating provides thermal resistance and extended tool life in high-temperature cutting environments. At 47 mm overall length with a 9.20 mm flute length and a 7xD maximum drilling depth ratio, the 9064010011500 is suited for controlled, short-cycle drilling applications where dimensional accuracy is critical. It is installed by machining professionals and tool-room technicians working in precision fabrication environments.

This micro drill bit is designed for use in CNC machining centers, drill presses, and precision drilling fixtures. Its primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloy. The right-hand spiral flute geometry and web-thinned point support chip evacuation in both ferrous and non-ferrous materials. The straight-cylindrical shank with a 3.00 mm shank diameter allows direct clamping in standard collet chucks and drill chucks sized for that diameter.

Key Features

• Solid carbide construction in material grade K40 for rigidity and wear resistance at micro diameters
• TiAlN coating for thermal protection and extended tool life in ferrous and high-temperature alloys
• 140-degree faceted point reduces thrust and improves entry accuracy on hard materials
• Web-thinned geometry supports chip evacuation and lowers cutting forces
• 7xD flute-by-diameter ratio provides extended reach relative to drill diameter
• Straight-cylindrical shank at 3.00 mm diameter for compatibility with standard collet and drill chuck systems
• Right-hand spiral flute with regular spiral type for predictable chip flow

Compatibility

Designed as a Series 6400 and 6401 GUHRING micro drill bit. Compatible with workpiece materials including cast iron, stainless steel, steel, aluminum, and titanium alloy. Fits collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation and use of this tool should be performed by qualified machinists or toolroom technicians. Ensure the machine spindle and chuck are fully stopped and de-energized before inserting or removing the bit. Secure the 3.00 mm shank firmly in a collet or chuck rated for the shank diameter to prevent runout at micro diameters. Observe manufacturer-recommended feed rates and spindle speeds for the target workpiece material to avoid breakage at this diameter.
