Accupro A-6100082R Micro Drill Bit 0.0323 in Solid Carbide

Product Description

The ACCUPRO A-6100082R is a solid carbide micro drill bit engineered for small-diameter precision drilling applications. At 0.0323 inches in diameter, it is built for tight-tolerance work where standard jobber bits are too large or too imprecise. The 120-degree point angle suits harder workpiece materials, and the bright uncoated finish keeps the cutting edge consistent without added coating thickness. The overall length is 30.00 mm with a 6.30 mm flute length, providing adequate chip clearance in shallow bores. A straight cylindrical shank at 1.50 mm fits standard collet chucks. This bit is sold individually but requires a minimum order quantity of 10 units.

This micro drill bit is suited for machinists, tool and die makers, and precision fabricators working in electronics, medical device manufacturing, aerospace components, instrumentation, or any application demanding small-diameter holes in metal, circuit board substrates, or similar materials. The miniature series designation indicates it is purpose-built for micro-drilling setups rather than general-purpose use. Right-hand cutting direction is standard for conventional drill press and CNC spindle operation.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• 0.0323 inch drill diameter for tight-tolerance small-hole applications
• 120-degree point angle suited to harder workpiece materials
• Bright uncoated finish maintains consistent edge geometry without coating buildup
• Straight cylindrical shank at 1.50 mm diameter for standard collet chuck compatibility
• Spiral flute with regular spiral type for efficient chip evacuation in shallow bores

Compatibility

Designed for use in CNC machining centers, micro-drill presses, and precision manual drill presses equipped with collet chucks accepting a 1.50 mm straight cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-diameter tooling. Secure the shank fully in the collet chuck and verify runout before beginning a cut, as micro bits are highly sensitive to misalignment. Do not exceed the recommended feed and speed parameters for the workpiece material and bit diameter. Solid carbide bits are brittle and will fracture under lateral load or excessive feed pressure.
