Guhring 9038990006000 Micro Drill Bit 0.6mm Carbide Tialn

Product Description

The GUHRING 9038990006000 is a solid carbide micro drill bit engineered for precision drilling in demanding production and toolroom environments. It carries a 0.6 mm diameter (0.0236 inches) with a 140-degree faceted point and a TiAlN coating that extends tool life in abrasive and high-temperature cutting conditions. The bit runs a right-hand spiral flute with a web-thinned point, reducing entry force and improving chip evacuation in small-diameter applications. At 38 mm overall length with a 3 mm straight-cylindrical shank, it mounts directly in standard collet chucks and drill chucks used on CNC machining centers and precision drill presses. Machinists and toolroom technicians install this bit for micro-hole work requiring tight tolerances.

This drill bit is suited for drilling cast iron and steel workpieces in applications where hole diameter accuracy and surface finish are critical. The h7 shank diameter tolerance ensures consistent seating in precision collet systems. The 5xD flute-to-diameter ratio and 6.10 mm maximum drilling depth (0.24 inches) make it appropriate for shallow, through-hole operations in production machining, printed circuit board tooling support fixtures, mold and die work, and similar precision metalworking tasks. It is sold individually and intended for professional machining environments.

Key Features

• Solid carbide construction from K40 grade material for rigidity and wear resistance in hard workpiece materials
• TiAlN coating improves heat resistance and extends tool life in ferrous materials
• 140-degree faceted point with web thinning reduces thrust force and improves hole entry accuracy
• Right-hand spiral flute with regular spiral type promotes consistent chip evacuation
• h7 diameter tolerance on the 3 mm straight-cylindrical shank ensures precise collet fitment
• Series 3899 design rated for cast iron (K) and steel (P) workpiece material groups

Compatibility

Designed for use in cast iron and steel workpieces as designated by material codes K and P. Compatible with standard collet chucks and drill chucks accepting a 3 mm straight-cylindrical shank. No coolant-through capability; intended for external coolant or dry cutting setups.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with micro-diameter tooling. Before mounting, power down and lock out the spindle drive per machine-specific lockout/tagout procedures. Seat the shank fully in the collet and torque the chuck to the machine manufacturer specification. Micro drills are brittle at this diameter — avoid side loading, confirm runout with an indicator before drilling, and use appropriate feed and speed parameters for the workpiece material to prevent bit fracture.
