Accupro A-6200300R Micro Drill Bit 3.00 Mm Solid Carbide

Product Description

The ACCUPRO A-6200300R is a solid carbide micro drill bit designed for precision drilling in miniature and close-tolerance applications. It measures 3.00 mm (0.1181 inches) in diameter with a 140-degree drill point angle, making it well suited for materials that require a flatter entry geometry to reduce walking and chipping. The overall length is 50.00 mm with a 21.00 mm flute length and a straight cylindrical shank. The bright, uncoated finish keeps the tool profile true to ground dimensions. This bit is installed by machinists, tool and die makers, and precision fabricators working on CNC mills, drill presses, and manual machines.

This micro drill bit fits into precision machining workflows where small-diameter, tight-tolerance holes are required. It is suited for ferrous and non-ferrous metals, printed circuit board materials, plastics, and composite substrates. The miniature series designation indicates it is intended for fine-pitch drilling operations where standard-shank drill bits lack the required diameter precision. It is used in job shops, electronics manufacturing, and production environments where repeatable hole quality at small diameters is critical.

Key Features

• 3.00 mm (0.1181 inches) drill diameter for micro and miniature hole applications
• 140-degree drill point angle reduces thrust and minimizes material deformation at entry
• Solid carbide construction provides rigidity and wear resistance in demanding materials
• Bright, uncoated finish maintains precise ground dimensions without coating buildup
• Spiral flute with straight cylindrical shank for standard collet and chuck compatibility
• 50.00 mm overall length with 21.00 mm flute length balances reach and rigidity

Compatibility

Designed as an OEM-style miniature series drill bit compatible with standard 3.00 mm collets, ER-series collet chucks, and precision drill chucks used on CNC machining centers, CNC drill presses, and manual machines accepting straight cylindrical shanks.

Installation Notes

This drill bit is installed by machinists and precision fabricators. Secure the shank fully in a collet or drill chuck and verify runout before drilling. Power down and lock out the spindle before changing tooling. Use appropriate cutting fluid or dry cutting practice as specified for the workpiece material. Do not exceed the recommended RPM range for the diameter and material combination.
