Accupro A-6120261R Micro Drill Bit 2.61 Mm Solid Carbide

Product Description

The ACCUPRO A-6120261R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 2.61 mm diameter (0.1028 inches), a 120-degree point angle, and a bright uncoated finish that suits general-purpose drilling in a range of materials. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is 38.00 mm with a 14.00 mm flute length. Right-hand spiral flutes promote efficient chip evacuation during operation. This bit is part of the Miniature series and is intended for machinists, toolmakers, and precision fabricators working on small-diameter hole applications.

This micro drill bit is suited for use in CNC machining centers, drill presses, and precision hand-held equipment where small-diameter accuracy is critical. It performs well in ferrous and non-ferrous metals, plastics, and composites at appropriate feed and speed rates. The solid carbide construction maintains rigidity in micro-drilling scenarios where high-speed steel tooling may deflect or wear prematurely. This bit is sold individually with a minimum order quantity of 10 units per order.

Key Features

• 2.61 mm diameter solid carbide construction for rigidity and wear resistance in micro drilling
• 120-degree standard point angle for accurate entry and reduced walking
• Bright uncoated finish suitable for a wide range of workpiece materials
• Right-hand cut with regular spiral flutes for efficient chip removal
• 3.00 mm straight-cylindrical shank for compatibility with standard collets and chucks
• 38.00 mm overall length with 14.00 mm flute length in a compact Miniature series profile

Compatibility

Designed as a standard miniature drill bit for use in CNC machining centers, drill presses, and rotary tool setups accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists familiar with micro-drilling feed and speed parameters. Secure the shank fully in a collet or drill chuck rated for the shank diameter before operating. Ensure the spindle and workpiece are properly secured to minimize vibration, which can cause bit breakage at small diameters. Coolant-through is not supported on this bit, so external coolant or cutting fluid application should be evaluated based on workpiece material.
