Guhring 9003010000600 Micro Drill Bit 0.0024 in Cobalt

Product Description

The GUHRING 9003010000600 is a cobalt micro drill bit engineered for precision drilling in small-diameter applications. At 0.0024 inches in diameter and 0.984 inches in overall length, this bit is built for high-accuracy work in materials where dimensional tolerance is critical. It features a 118-degree faceted point, a spiral flute with web-thinned, tapered web configuration, and a straight-cylindrical shank. Manufactured to DIN 1899 specification, it carries a diameter tolerance of +0.000 to -0.004 mm, making it suitable for applications where oversized holes are not acceptable. The bright/uncoated finish is standard for cobalt-grade tooling in this size range.

This micro drill bit is designed for use in precision machining environments where extremely small hole diameters are required. Its primary rated workpiece material is aluminum, with secondary suitability for titanium alloy. The 5xD flute-to-diameter ratio and 0.012-inch maximum drilling depth make this bit appropriate for shallow, tight-tolerance bores. Typical users include machinists, tool-and-die technicians, and precision fabricators working on aerospace, medical device, or electronics components. Right-hand cutting direction is standard for conventional drill press and CNC spindle operation.

Key Features

• 0.0024-inch drill diameter with +0.000 to -0.004 mm tolerance for tight-fit applications
• 118-degree faceted point with web-thinned, tapered web for reduced entry force
• Cobalt construction provides heat resistance and edge retention in hard and abrasive materials
• Spiral flute, right-hand cut — compatible with standard drill press and CNC spindle setups
• DIN 1899 specification ensures dimensional conformance to international standards
• Bright/uncoated finish — no coating interference in micro-diameter bores

Compatibility

Rated for use in aluminum (material code K, M, N, P) as the primary workpiece material and titanium alloy (material code S) as the secondary workpiece material. Straight-cylindrical shank with 1.00 mm shank diameter fits standard micro drill chucks and precision collet holders designed for that shank size.

Installation Notes

Installation and use of this micro drill bit should be performed by qualified machinists or tooling technicians familiar with precision drilling operations. Secure the workpiece fully before engaging the spindle, and verify chuck or collet runout is within acceptable limits for the 1.00 mm shank diameter — excessive runout at this scale will destroy the bit and damage the workpiece. Use appropriate cutting fluid or lubrication rated for the target material. Coolant-through is not supported by this bit design.
