Accupro A-6120248R Micro Drill Bit 2.48mm Solid Carbide

Product Description

The ACCUPRO A-6120248R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It features a 2.48 mm (0.0976 inches) drill diameter with a 120-degree point angle and a straight-cylindrical shank measuring 3.00 mm in diameter. The bright/uncoated finish suits applications where coating buildup or chemical interaction is a concern. With an overall length of 38.00 mm and a 12.00 mm flute length, this bit is built for controlled, accurate entry in small-diameter work. It is part of the Miniature Series and is suited for machinists, toolmakers, and precision fabricators working with small-bore requirements.

This micro drill bit is used in precision machining environments where small-diameter holes are required in metal, composite, or similar materials. The right-hand cutting direction and spiral flute design support consistent chip evacuation during operation. Typical applications include instrument manufacturing, mold work, electronics fabrication, and other trades requiring repeatable micro-bore accuracy. The solid carbide construction maintains rigidity at small diameters, reducing deflection during cutting.

Key Features

• 2.48 mm (0.0976 inches) drill diameter for precision micro-bore applications
• Solid carbide construction provides rigidity and wear resistance at small diameters
• 120-degree standard point angle for controlled entry and reduced walking
• Bright/uncoated finish — no coating interaction with sensitive workpiece materials
• Spiral flute type with regular spiral for consistent chip evacuation
• Straight-cylindrical shank for compatibility with standard collets and chucks

Compatibility

Designed for use in CNC machining centers, drill presses, and precision hand-held spindles equipped with collets or chucks sized for a 3.00 mm straight-cylindrical shank.

Installation Notes

This bit should be installed and operated by qualified machinists familiar with micro-tooling practices. Ensure the spindle and collet are clean and properly torqued before use to prevent runout at small diameters. At micro-drill diameters, feed rate and RPM must be appropriate for the workpiece material to avoid breakage — consult published speeds and feeds for solid carbide micro drills. Coolant-through is not supported on this bit; apply external coolant or cutting fluid as needed per shop practice.
