Accupro A-6120244R Micro Drill Bit 2.44mm Solid Carbide

Product Description

The ACCUPRO A-6120244R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It carries a 2.44 mm (0.0961 inch, wire size 41) cutting diameter with a 120-degree drill point angle and a straight-cylindrical shank measuring 3.00 mm in diameter. The overall length is 38.00 mm, and the flute length runs 12.00 mm. Manufactured from solid carbide in a bright, uncoated finish, this bit delivers the rigidity and edge retention required for small-diameter drilling in metals, composites, and engineered plastics. Right-hand cutting direction and a standard point type make it a straightforward fit for CNC and benchtop drilling operations.

This bit belongs to the Miniature Series and is suited for precision machining environments where small-diameter hole quality matters. Typical applications include printed circuit board drilling, instrument components, medical device manufacturing, mold work, and other operations that demand tight positional accuracy and consistent hole finish. It is sold individually (package quantity of 1) and is appropriate for machinists, toolmakers, and precision fabricators working with CNC machining centers, drill presses, or high-speed spindles equipped to run small-diameter carbide tooling.

Key Features

• Solid carbide construction provides high rigidity and wear resistance for small-diameter drilling
• 2.44 mm cutting diameter with wire size 41 designation for precision tolerance work
• 120-degree drill point angle for controlled entry and reduced walking on hard materials
• Bright, uncoated finish compatible with a wide range of workpiece materials
• Straight-cylindrical shank at 3.00 mm diameter for standard collet and chuck mounting
• Right-hand spiral flute with standard point type for consistent chip evacuation

Compatibility

Designed as an OEM-style replacement or direct-use micro drill bit for applications requiring a wire gauge 41 (2.44 mm) solid carbide drill in standard straight-shank collets or chucks sized for a 3.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists familiar with small-diameter carbide tooling. Ensure the spindle, collet, and chuck are clean and properly sized for the 3.00 mm straight shank before securing the bit. Carbide micro drills are brittle and susceptible to breakage from side loads, misalignment, or excessive feed rates — confirm runout and alignment before operation. Refer to the machine manufacturer and tooling guidelines for appropriate spindle speeds and feed rates for the workpiece material.
