Accupro A-6100151R Micro Drill Bit No. 53 Solid Carbide

Product Description

The ACCUPRO A-6100151R is a solid carbide micro drill bit designed for high-precision drilling in small-diameter applications. This wire gauge No. 53 bit measures 0.0594 inches (1.51 mm) in diameter and delivers clean, accurate holes in hard and abrasive materials where high-speed steel tooling falls short. The 120-degree standard point angle promotes accurate entry and reduces walking on initiation. A bright, uncoated finish makes surface condition and wear easy to inspect during use. Machinists, tool and die technicians, and precision fabricators use this bit for tight-tolerance work in metals, composites, and engineered plastics.

This bit is suited for CNC machining centers, benchtop drill presses, and precision hand-held spindle applications requiring small-diameter through-holes or pilot holes. The miniature series designation indicates it is optimized for micro-drilling operations where rigidity and concentricity are critical. The straight-cylindrical shank with a 2.00 mm shank diameter seats securely in standard collets and drill chucks sized for miniature tooling. Right-hand spiral flute geometry evacuates chips efficiently in standard clockwise-rotation spindles.

Key Features

• Solid carbide construction provides superior hardness and rigidity over high-speed steel in abrasive or hard materials
• No. 53 wire gauge size: 0.0594 inches (1.51 mm) drill diameter
• 120-degree standard point angle for accurate hole entry and reduced tip walking
• Bright, uncoated finish allows straightforward visual inspection of cutting edge condition
• Regular spiral flute promotes effective chip evacuation in clockwise-rotation setups
• Straight-cylindrical shank (2.00 mm) for secure seating in standard miniature collets and chucks

Compatibility

Designed as an OEM-style replacement and standard production micro drill bit for use in any CNC or manual spindle accepting a straight-cylindrical 2.00 mm shank and capable of holding wire gauge No. 53 miniature tooling.

Installation Notes

Installation is performed by machinists and precision tooling technicians. Power down and lock out the spindle before changing tooling. Seat the shank fully and evenly in the collet or chuck before tightening to manufacturer torque specifications for the toolholder. Micro-diameter carbide tooling is brittle — avoid side-loading, abrupt feed changes, or over-clamping, which can cause premature fracture.
