Accupro A-6120026R Micro Drill Bit 0.0102 in Solid Carbide

Product Description

The ACCUPRO A-6120026R is a solid carbide micro drill bit designed for precision drilling at extremely small diameters. Built for the miniature series, this bit measures 0.0102 inches in diameter with a 120-degree drill point angle and a bright uncoated finish. The overall length is 25.00 mm with a 1.30 mm flute length and a 1.00 mm straight-cylindrical shank. Right-hand cutting direction and a standard spiral flute geometry make this bit suitable for consistent, repeatable performance in tight-tolerance applications where bit deflection and runout must be minimized.

This micro drill bit is used in precision machining, electronics manufacturing, printed circuit board fabrication, medical device production, and other applications requiring extremely fine hole diameters. The solid carbide construction handles hard and abrasive materials where high-speed steel bits would wear prematurely. Machinists, tool-and-die makers, and electronics fabricators working on CNC mills, drill presses, and micro-machining centers are the primary users of this bit.

Key Features

• 0.0102 inch diameter for ultra-fine, tight-tolerance hole making
• Solid carbide construction resists wear in hard and abrasive materials
• 120-degree standard point angle suited for a wide range of workpiece materials
• Bright uncoated finish maintains dimensional accuracy at micro scale
• Straight-cylindrical shank with 1.00 mm diameter for secure chuck engagement
• Regular spiral flute type promotes chip evacuation in shallow micro holes

Compatibility

Designed as an OEM-style replacement or standard stock micro drill bit for CNC machining centers and precision drill presses equipped with collets or chucks accepting a 1.00 mm straight-cylindrical shank.

Installation Notes

Micro drill bits at this diameter are fragile and require a rigid, low-runout spindle and collet system to prevent premature breakage. Ensure the machine spindle and workpiece fixture are securely clamped and free of vibration before starting. Feed rates and spindle speeds should be set conservatively and within the machine and material manufacturer recommendations. Do not apply side load or attempt to use this bit for anything other than axial drilling.
