Accupro A-6120154R Micro Drill Bit 1.54 Mm Solid Carbide

Product Description

The ACCUPRO A-6120154R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built on a miniature series platform, it features a 1.54 mm cutting diameter (0.0606 inches decimal equivalent) and a 120-degree point angle that promotes accurate entry and reduces walking on hard or dense materials. The bright, uncoated finish maintains tight dimensional tolerances. At 38 mm overall length with a 7.20 mm flute length, this bit is sized for shallow, high-accuracy holes. Machinists, toolmakers, and precision fabricators working with small-diameter bores will find this bit suited to demanding production and prototype work.

This micro drill bit is used in machining centers, CNC drilling operations, manual drill presses, and hand-held precision drilling fixtures where small-diameter holes are required. Typical applications include printed circuit board work, instrument components, watch and clock components, medical device parts, and any precision metalworking application calling for sub-2 mm hole diameters. The right-hand spiral flute and straight cylindrical shank allow it to seat in standard collets and chucks sized for a 2.00 mm shank diameter.

Key Features

• 1.54 mm cutting diameter with 0.0606 inch decimal equivalent for tight-tolerance drilling
• Solid carbide construction provides rigidity and wear resistance in hard or abrasive materials
• 120-degree standard point angle for accurate entry and reduced drill walking
• Bright, uncoated finish maintains precise dimensional tolerances
• Right-hand cut, regular spiral flute promotes efficient chip evacuation in shallow holes
• 2.00 mm straight cylindrical shank fits standard collets and micro chucks

Compatibility

Designed as a miniature-series micro drill bit compatible with standard collets, drill chucks, and tool holders accepting a 2.00 mm straight cylindrical shank diameter.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists familiar with micro-diameter tooling. Ensure the spindle and tool holder are fully powered down and locked before inserting or removing the bit. Use appropriate collets or micro chucks rated for 2.00 mm shanks to prevent tool runout, which is critical at this diameter. Micro carbide tooling is brittle — avoid side loading, improper feed rates, or re-chucking a bent shank, as carbide will fracture rather than bend.
