Guhring 9003010015000 Cobalt Micro Drill Bit 1.5 Mm

Product Description

The GUHRING 9003010015000 is a cobalt micro drill bit designed for precision drilling in small-diameter applications. Built to DIN 1899 standards, it features a 1.5 mm diameter, a 118-degree faceted point, and a web-thinned, tapered web configuration that reduces thrust and improves chip evacuation at entry. The overall length is 30 mm, with a 9.5 mm flute length and a 2 mm straight-cylindrical shank. The bright, uncoated cobalt construction provides heat resistance and edge retention when drilling non-ferrous metals, aluminum, and titanium alloys. This bit is a single-piece unit sold in multiples of ten.

This micro drill bit is suited for precision metalworking applications in production, toolroom, and maintenance environments. Its 5xD flute-to-diameter ratio and right-hand spiral flute geometry handle aluminum as a primary workpiece material and titanium alloy as a secondary workpiece material. The maximum drilling depth is 7.25 mm (0.285 inches). It is appropriate for use in CNC machining centers, drill presses, and high-speed hand tools where tight tolerances and consistent hole quality are required in small-diameter work.

Key Features

• 1.5 mm diameter with a diameter tolerance of +0.000 to -0.004 mm for consistent, accurate hole sizing
• 118-degree faceted point with web thinning reduces entry thrust and improves centering
• Cobalt tool material provides elevated heat and wear resistance compared to standard HSS
• Tapered web configuration with regular spiral flute promotes efficient chip flow in deep micro holes
• Straight-cylindrical 2 mm shank fits standard collets and drill chucks without modification
• Conforms to DIN 1899 specification for consistent interchangeability with other standard micro drill tooling

Compatibility

Designed as an OEM-style replacement and production micro drill conforming to DIN 1899, suitable for use in standard straight-shank collet chucks and drill chucks accepting 2 mm shank diameters. Rated for aluminum (material code K, M, N, P) as primary workpiece material and titanium alloy (material code S) as secondary workpiece material.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Secure the shank fully in a collet or drill chuck and verify runout before drilling. Shut down and de-energize the machine spindle before inserting or removing the bit. Do not exceed the rated maximum drilling depth of 7.25 mm without pecking cycles, as micro-diameter drills are susceptible to deflection and breakage in deeper applications.
