Accupro A-6100154R Micro Drill Bit 1.54 Mm Solid Carbide

Product Description

The ACCUPRO A-6100154R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a cutting diameter of 1.54 mm (0.0606 inches) and a 120-degree drill point angle, this bit delivers clean entry and accurate hole placement in hard and abrasive materials. The bright/uncoated finish maintains dimensional accuracy at the cutting edge. At 38.00 mm overall length with a 12.00 mm flute length and a 2.00 mm straight-cylindrical shank, this miniature-series bit fits standard collet and drill chuck setups used in precision machining and circuit board or micro-component work.

This micro drill bit is suited for use in CNC machining centers, benchtop drill presses, and hand-held precision drilling fixtures where small-diameter hole accuracy is critical. Typical applications include printed circuit board fabrication, instrument manufacturing, tooling, fixture work, and precision metalworking in aerospace, electronics, and medical device production environments. Right-hand spiral flutes evacuate chips efficiently during through-hole and blind-hole drilling operations.

Key Features

• 1.54 mm (0.0606 inches) cutting diameter for micro-precision drilling
• 120-degree drill point angle for accurate self-centering entry
• Solid carbide construction provides rigidity and wear resistance in hard materials
• Bright/uncoated finish maintains close dimensional tolerances at the tip
• Regular spiral, straight-cylindrical shank fits standard collets and chucks
• 12.00 mm flute length with efficient chip evacuation via spiral flute design

Compatibility

Designed as an OEM-style replacement or direct-fit micro drill bit for precision drilling equipment accepting a 2.00 mm straight-cylindrical shank in the miniature drill bit series.

Installation Notes

This bit should be installed by a qualified machinist or tooling technician familiar with micro-diameter tooling procedures. Secure the shank fully in a compatible collet or drill chuck before operation and verify runout with a dial indicator where tolerances are critical. Micro carbide bits are brittle and should never be used with excessive feed pressure or side loading. Inspect the cutting edge before each use, as carbide micro drills can chip or fracture if dropped or improperly stored.
