Accupro A-6120051R Micro Drill Bit No. 76 0.0201 in Solid Carbide

Product Description

The ACCUPRO A-6120051R is a solid carbide micro drill bit designed for precision drilling in miniature and close-tolerance applications. Built to wire gauge size No. 76, it produces a 0.0201-inch diameter hole with a 120-degree drill point angle that centers quickly and minimizes walking on hard materials. The overall length measures 25.00 mm, with a 1.00 mm straight-cylindrical shank and a 2.40 mm spiral flute length. The bright, uncoated finish keeps heat transfer predictable and makes wear inspection straightforward. This bit is suited for machinists, toolmakers, and precision fabricators working on circuit boards, instrument components, and other fine-detail workpieces.

This micro drill bit is intended for right-hand cutting operations on CNC machining centers, drill presses, and precision bench machines where small-diameter, high-accuracy holes are required. The miniature series designation reflects its compact geometry, making it a fit for electronics manufacturing, watchmaking, medical device fabrication, and any trade application that demands consistent results at sub-0.025-inch diameters. It is sold individually per package, with a minimum order quantity of 10 units.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard and abrasive materials
• No. 76 wire gauge size producing a 0.0201-inch diameter bore
• 120-degree standard point angle for fast engagement and reduced thrust force
• Spiral flute type with regular spiral promotes chip evacuation in short flute length
• Bright uncoated finish allows easy visual inspection of cutting edges
• Straight-cylindrical shank compatible with standard collet and chuck toolholding systems

Compatibility

Designed for use in standard straight-shank collets and drill chucks accepting a 1.00 mm shank diameter. Suitable for right-hand spindle machines in CNC and manual configurations.

Installation Notes

Micro drill bits of this size should be installed and run by machinists or toolmakers familiar with small-diameter tooling practices. Ensure the spindle and toolholder are clean and concentric before chucking to minimize runout, which can snap carbide bits at this diameter. Power down or e-stop the machine fully before changing tooling. Avoid side loading or interrupted cuts that exceed the structural limits of the 1.00 mm shank.
