Accupro A-6100102R Micro Drill Bit 1.02 Mm Solid Carbide

Product Description

The ACCUPRO A-6100102R is a miniature series solid carbide micro drill bit designed for precision drilling in small-diameter applications. The bit measures 1.02 mm (0.0402 inches) in diameter with a 30 mm overall length and an 8 mm flute length. A 120-degree point angle promotes accurate entry and reduces walking on hard or dense materials. The bright, uncoated finish is standard for solid carbide tooling where coating is not required by the application. This bit is suited for machinists, tool and die makers, and precision fabricators working in electronics, medical device, or fine mechanical component production.

This micro drill bit fits applications requiring tight-tolerance small-diameter holes in materials where rigidity and geometry accuracy matter. The straight-cylindrical shank at 1.50 mm diameter seats cleanly in standard collets and chucks sized for miniature tooling. Right-hand cut with a regular spiral flute pattern handles chip evacuation in typical drilling passes. It is commonly used in CNC machining centers, drill presses, and manual precision machines in shop environments requiring repeatable micro-bore work.

Key Features

• 1.02 mm drill diameter (0.0402 inches) for precision micro-bore applications
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 120-degree standard point angle for accurate entry and reduced deflection
• 30 mm overall length with 8 mm spiral flute length
• Straight-cylindrical shank at 1.50 mm for compatibility with standard miniature collets
• Bright uncoated finish — no coating interference in sensitive tolerance applications

Compatibility

Designed for use in CNC machining centers, drill presses, and precision drilling equipment that accept straight-cylindrical shank tooling in the miniature size range.

Installation Notes

Installation and use of this bit should be performed by qualified machinists familiar with micro-diameter tooling. Secure the shank fully in a collet or chuck rated for the 1.50 mm shank diameter before operation. At micro diameters, feed rate and spindle speed selection are critical — consult tooling data for the specific workpiece material to avoid bit breakage. Inspect the cutting edge and point under magnification before each use to verify the bit is undamaged.
