Accupro A-6120260R Micro Drill Bit 2.6 Mm Solid Carbide

Product Description

The ACCUPRO A-6120260R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built to miniature-series specifications, it features a 2.6 mm diameter cutting edge, a 120-degree point angle, and a spiral flute geometry for efficient chip evacuation. The bright, uncoated finish is suitable for use in a wide range of materials without the added friction of a coating layer. With an overall length of 38 mm and a 3.0 mm straight-cylindrical shank, this bit is sized for use in CNC machines, drill presses, and precision hand tools. Machinists, tool and die makers, and production drilling technicians are the primary users of this tool.

This micro drill bit is intended for applications requiring small-diameter, high-precision holes. It is well suited to work in printed circuit board fabrication, instrument manufacturing, medical device components, and other fine-tolerance production environments. The right-hand cut and standard point type make it a straightforward drop-in for conventional drilling setups. The miniature series designation indicates it is optimized for light-duty, small-feature work rather than heavy stock removal.

Key Features

• 2.6 mm cutting diameter with a decimal inch equivalent of 0.1024 inches for cross-reference to imperial tooling charts
• 120-degree standard point angle for accurate entry and reduced thrust force in small-diameter drilling
• Solid carbide construction provides superior hardness and wear resistance compared to high-speed steel alternatives
• Spiral flute design with regular spiral type promotes chip evacuation and reduces heat buildup
• Bright, uncoated finish maintains dimensional consistency and suits a broad range of workpiece materials
• Straight-cylindrical shank at 3.0 mm diameter ensures secure collet or chuck engagement

Compatibility

Designed as an OEM-style miniature series replacement or replenishment drill bit for precision drilling setups that accept a 3.0 mm straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or tooling technician familiar with small-diameter carbide tooling. Secure the shank fully in a collet or drill chuck rated for the spindle speed required by the workpiece material. Carbide tooling is brittle and should not be subjected to lateral loading or used in setups with excessive runout, as this can cause premature breakage. Inspect the cutting edges before each use and replace the bit at the first sign of chipping or wear.
