Guhring 9003010005000 Cobalt Micro Drill Bit 0.0197 in

Product Description

The GUHRING 9003010005000 is a cobalt micro drill bit engineered for precision drilling in small-diameter applications. Built to DIN 1899 specification, this bit measures 0.0197 inches in diameter with an overall length of 0.984 inches and a 118-degree faceted point angle. The cobalt construction delivers the hardness and heat resistance required when drilling into aluminum, titanium alloy, and other demanding workpiece materials. The web-thinned, tapered web configuration reduces thrust force at entry, which is critical when working at this diameter. A bright, uncoated finish maintains tight dimensional tolerances. This bit is handled by machinists, tool and die makers, and precision fabricators working in high-accuracy production environments.

Designed for micro-drilling applications, this bit is suited to light-duty machining operations on aluminum, titanium alloy, and similar materials where small-diameter hole accuracy is required. The spiral flute geometry and straight-cylindrical shank allow use in standard collet chucks and precision drill presses. With a maximum drilling depth of 0.104 inches and a flute-to-diameter ratio of 5xD, it is well matched to shallow, tight-tolerance holes in thin workpieces or precision components. The Series 301 designation places it within a defined product family for easy cross-referencing in production environments.

Key Features

• Cobalt tool material provides superior hardness and thermal resistance compared to standard high-speed steel
• 118-degree faceted point with web thinning reduces entry thrust and improves centering at small diameters
• Bright, uncoated finish maintains a diameter tolerance of +0.000 to -0.004 mm
• Spiral flute, right-hand cut geometry for consistent chip evacuation in micro-drilling applications
• Straight-cylindrical shank, 1.00 mm diameter, compatible with standard precision collet systems
• Conforms to DIN 1899 specification for standardized micro drill geometry

Compatibility

Rated for primary use in aluminum (material codes K, M, N, P) and secondary use in titanium alloy (material code S). Designed as an OEM-specification micro drill bit per DIN 1899 for use in standard precision collet chucks and drill presses accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with micro-drilling operations. Secure the straight-cylindrical shank in a precision collet or drill chuck rated for the shank diameter before operation. At this diameter, runout control is critical — use only chucks and spindles with minimal TIR to avoid bit deflection or breakage. Always verify spindle speed and feed rate against the workpiece material specifications before drilling.
