Guhring 9003010014000 Cobalt Micro Drill Bit Size 54

Product Description

The GUHRING 9003010014000 is a cobalt micro drill bit in wire gauge size 54, engineered for precision drilling in small-diameter applications. Built to DIN 1899 specification, this bit measures 0.0551 inches in diameter with an overall length of 0.984 inches and a spiral flute length of 9.50 mm. The 118-degree faceted point angle provides accurate entry and reduced walking on initiation. A web-thinned, tapered web configuration reduces thrust force during penetration. The bright, uncoated cobalt construction offers heat resistance suitable for demanding materials without an additional coating. This bit is installed by machinists, tool and die technicians, and precision manufacturing professionals working with small-hole applications.

The 9003010014000 is designed for drilling aluminum as its primary workpiece material, with titanium alloy listed as a secondary material application. The right-hand spiral flute configuration evacuates chips efficiently during through and blind hole operations. With a maximum drilling depth of 0.291 inches and a 5xD flute-to-diameter ratio, this bit suits short, precise holes in thin stock and small-format workpieces common in aerospace, electronics, and precision machining environments. The straight-cylindrical shank at 1.50 mm diameter fits standard micro drill chucks and collet holders.

Key Features

• Wire gauge size 54 with 0.0551-inch decimal diameter for micro-scale precision drilling
• 118-degree faceted point with web thinning for reduced entry thrust and accurate positioning
• Cobalt tool material provides elevated heat resistance compared to standard high-speed steel
• Spiral flute with regular spiral type for consistent chip evacuation in aluminum and titanium alloy
• Bright, uncoated finish suitable where coating residue or dimensional buildup is not acceptable
• Conforms to DIN 1899 specification for dimensional consistency and interchangeability

Compatibility

Designed as a DIN 1899 Series 301 micro drill bit for use in precision drilling applications with aluminum as the primary workpiece material and titanium alloy as a secondary material. Fits standard 1.50 mm straight-cylindrical shank collets and micro drill chucks.

Installation Notes

Installation and use should be performed by qualified machinists or tooling technicians familiar with micro-drill operations. Secure the straight-cylindrical shank firmly in a compatible collet or chuck before operation and verify runout before drilling. Power down and de-energize all equipment before changing bits. Micro-diameter drill bits are brittle — avoid side loading, excessive feed rates, or unsupported workpieces that can cause breakage.
