Guhring 9064080027000 Micro Drill Bit 0.1063 in Carbide

Product Description

The GUHRING 9064080027000 is a solid carbide micro drill bit designed for precision drilling in demanding industrial and machining applications. Built from submicron-grade carbide and coated with TiAlN for heat and wear resistance, this bit handles tough workpiece materials including stainless steel, cast iron, and steel with consistent accuracy. It measures 0.1063 inches in diameter with a 135-degree faceted drill point and a web-thinned, tapered web configuration that reduces entry force and improves chip flow. At 66.00 mm overall length with a 30.00 mm flute length and 27.30 mm maximum drilling depth, it is engineered for tight-tolerance micro-drilling tasks performed by machinists and CNC operators.

This drill bit is suited for precision machining environments where small-diameter, high-accuracy holes are required in ferrous and non-ferrous materials. Primary workpiece materials include cast iron, stainless steel, and steel. Secondary workpiece materials include aluminum and titanium alloy. The straight-cylindrical shank with a 4.00 mm shank diameter and 31.00 mm shank length makes it compatible with standard collet and chuck systems used in CNC machining centers and precision drill presses. Its 8xD flute-by-diameter ratio supports deeper hole applications relative to bit diameter.

Key Features

• Submicron solid carbide construction for high rigidity and extended tool life in hard materials
• TiAlN coating provides thermal resistance and reduces wear at elevated cutting speeds
• 135-degree faceted point with web thinning reduces thrust force and improves hole entry accuracy
• Coolant-through design supports internal coolant delivery for heat management and chip evacuation
• Straight-cylindrical shank fits standard collet systems; shank diameter 4.00 mm
• Spiral flute with regular spiral type promotes consistent chip removal in deep-hole applications

Compatibility

Designed for use in CNC machining centers and precision drill presses with collet or chuck systems accepting a 4.00 mm straight-cylindrical shank. Primary workpiece materials are cast iron, stainless steel, and steel; secondary materials include aluminum and titanium alloy.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the machine powered down and locked out per OSHA lockout/tagout procedures. Secure the shank fully in a clean, undamaged collet or chuck and verify runout before operation. Confirm that the machine spindle and coolant-through system are compatible with the bit diameter and shank size before use. Do not exceed manufacturer-recommended feed and speed parameters for the workpiece material being machined.
