Guhring 9064000010000 Micro Drill Bit 1mm Carbide Tialn

Product Description

The GUHRING 9064000010000 is a solid carbide micro drill bit designed for precision drilling in demanding metalworking applications. It measures 1 mm in diameter (0.0394 inches) with an overall length of 47 mm and a flute length of 6 mm. The 140-degree faceted point geometry with web thinning reduces entry force and improves centering accuracy in hard and abrasive workpiece materials. A TiAlN coating increases surface hardness and heat resistance, extending tool life in high-speed and dry-cutting operations. This bit is suited for use in CNC machining centers, drill presses, and precision manual setups where small-diameter hole tolerances are critical.

The 9064000010000 belongs to GUHRING Series 6400 and is engineered for primary use in cast iron, stainless steel, and steel (ISO material groups K, M, and P). It also performs well in secondary materials including aluminum and titanium alloy (ISO groups N and S). The straight-cylindrical shank at 3 mm diameter fits standard collets and chucks used in production and job-shop environments. With a maximum drilling depth of 4.8 mm and a 4xD flute-to-diameter ratio, this bit is best suited for shallow, tight-tolerance bores typical in precision part manufacturing and toolroom work.

Key Features

• 1 mm drill diameter with m7 tolerance for tight, repeatable hole sizing
• 140-degree faceted point with web thinning for accurate entry and reduced thrust force
• TiAlN coating provides heat and wear resistance in dry or minimal-coolant cutting
• Solid carbide construction (K40 grade) for rigidity and edge retention in hard materials
• Straight-cylindrical 3 mm shank fits standard collets without adapters
• Right-hand spiral flute with regular helix for efficient chip evacuation in shallow bores

Compatibility

Designed as an OEM-style precision drill for use in standard collet chucks and drill holders accepting a 3 mm straight-cylindrical shank, compatible with CNC and manual setups requiring 1 mm bore capability.

Installation Notes

Installation and use of this micro drill bit should be performed by qualified machinists or tool-and-die professionals familiar with small-diameter carbide tooling. Secure the 3 mm shank firmly in a precision collet to minimize runout, which is critical at this diameter. Power down and fully stop the spindle before tool changes. Avoid side loads and interrupted cuts that can fracture carbide at small diameters.
