Accupro A-6100030R Micro Drill Bit 0.0118 in Solid Carbide

Product Description

The ACCUPRO A-6100030R is a solid carbide micro drill bit engineered for precision drilling at extremely small diameters. The bit measures 0.0118 inches in diameter with a 120-degree drill point angle and a 25.00 mm overall length. The bright, uncoated carbide construction delivers hardness and dimensional stability in demanding small-hole applications. The straight-cylindrical shank measures 1.00 mm in diameter and accepts standard collet chucks used in CNC machining centers, drill presses, and precision hand tools. Machinists and tooling specialists working in electronics manufacturing, medical device fabrication, and precision instrument production are the primary users of this bit.

This micro drill bit is suited for applications requiring tight-tolerance, small-diameter through-holes or blind holes in materials such as circuit boards, thin metals, and plastics. The 2.20 mm spiral flute length provides chip evacuation in shallow-depth drilling operations. The right-hand cutting direction is standard for conventional rotating spindles. The miniature series designation indicates this bit is designed for precision machining environments where diameter tolerances and runout are closely controlled.

Key Features

• 0.0118 inch drill diameter for micro and miniature hole applications
• Solid carbide construction for hardness and wear resistance
• 120-degree drill point angle suits a wide range of materials
• Bright, uncoated finish maintains tight dimensional tolerances
• Straight-cylindrical shank at 1.00 mm for collet chuck compatibility
• Right-hand spiral flute geometry promotes controlled chip evacuation

Compatibility

Designed as a miniature-series replacement or stock bit for CNC machining centers, micro drill presses, and precision drilling fixtures using standard collet systems sized for 1.00 mm straight-cylindrical shanks.

Installation Notes

Micro drill bits of this diameter require a precision collet chuck with minimal runout to prevent bit deflection and breakage. Always confirm spindle speed and feed rate settings are appropriate for the diameter before engaging the workpiece. Secure the workpiece firmly to avoid lateral movement during entry. Micro carbide bits are brittle and should never be used to pry, lever, or ream a hole.
