Guhring 9064000023000 Micro Drill Bit 2.3mm Carbide

Product Description

The GUHRING 9064000023000 is a solid carbide micro drill bit designed for precision drilling in demanding industrial and machining applications. Built to Series 6400 standards, it features a 140-degree faceted point angle and a TiAlN (titanium aluminum nitride) coating that extends tool life under high-heat cutting conditions. The bit measures 2.3 mm in diameter with an overall length of 59 mm and a flute length of 13.8 mm. A web-thinned geometry reduces thrust load at entry, making it well suited for small-diameter work in hard and abrasive workpiece materials. Machinists and tool-and-die professionals install this bit in CNC machining centers, drill presses, and precision hand tools.

This drill bit is engineered for use in cast iron, stainless steel, and steel as primary workpiece materials, with rated secondary compatibility in aluminum and titanium alloys. The 4xD flute-by-diameter ratio supports chip evacuation in deeper micro-hole applications, with a rated maximum drilling depth of 11 mm. The straight-cylindrical shank diameter of 4 mm fits standard collet and drill chuck systems. It is appropriate for residential, commercial, and industrial tool rooms where tight tolerances and repeatable hole geometry are required.

Key Features

• Solid carbide K40 grade construction for rigidity and wear resistance in abrasive materials
• TiAlN coating extends tool life by reducing heat buildup at the cutting edge
• 140-degree faceted point angle improves centering accuracy and reduces walking on entry
• Web-thinned geometry lowers thrust force for cleaner entry in small-diameter drilling
• Spiral flute design promotes chip evacuation during through-hole and blind-hole operations
• Right-hand cut with straight-cylindrical shank for compatibility with standard collets and chucks

Compatibility

Designed for use in cast iron, stainless steel, and steel as primary workpiece materials, with secondary suitability for aluminum and titanium alloys. The 4 mm straight-cylindrical shank fits standard collet systems and drill chucks that accept that shank diameter.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or toolroom professional familiar with small-diameter carbide tooling. Always secure the shank fully in a matched collet or chuck before operation, and confirm runout is within acceptable limits to prevent bit fracture. Carbide micro drills are brittle and should not be used with feeds or speeds outside the manufacturer-recommended range for the workpiece material. Inspect the cutting edge before each use and replace if chipping or wear is observed.
