Accupro A-6100105R Micro Drill Bit 1.05 Mm Solid Carbide

Product Description

The ACCUPRO A-6100105R is a miniature series solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 1.05 mm diameter, a 120-degree point angle, and a bright uncoated finish that suits general-purpose use across a range of base materials. The straight-cylindrical shank measures 1.50 mm in diameter, and the overall length is 30 mm with a flute length of 8 mm. Right-hand cut with a regular spiral flute, this bit is built for controlled chip evacuation at small diameters. Machinists and toolroom technicians working in precision manufacturing, electronics fabrication, or instrument assembly will find this bit suited to their close-tolerance drilling requirements.

This micro drill bit is intended for use in CNC machining centers, drill presses, and manual spindle applications where sub-2 mm hole diameters are required. It is commonly used in PCB drilling, small-part machining, mold work, and instrumentation manufacturing. The solid carbide construction maintains rigidity at small diameters where high-speed steel tooling tends to deflect or break. Its miniature series classification makes it appropriate for production environments that demand repeatable accuracy at micro-scale diameters.

Key Features

• 1.05 mm drill diameter for precision micro-scale hole drilling
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 120-degree point angle suits standard drilling applications in metal and similar materials
• Bright uncoated finish compatible with a wide range of workpiece materials
• Regular spiral flute with right-hand cut for controlled chip removal
• Straight-cylindrical shank at 1.50 mm fits standard collet and chuck toolholding

Compatibility

Designed as an OEM-style miniature series replacement drill bit suitable for precision drilling spindles, CNC machining centers, and benchtop drill presses equipped with collets or chucks capable of holding a 1.50 mm straight-cylindrical shank.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank firmly in a properly sized collet or chuck to minimize runout, which is critical at sub-2 mm diameters. Avoid applying excessive feed force, as solid carbide micro drills are brittle and will fracture under lateral load or workpiece misalignment.
