Accupro A-6120276R Micro Drill Bit 2.76mm Solid Carbide

Product Description

The ACCUPRO A-6120276R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built to a 120-degree point angle with a spiral flute and right-hand cut, this bit delivers clean, accurate holes in hard materials where standard tooling falls short. The bright, uncoated finish suits a wide range of base materials without the thermal complications of coated alternatives. At 2.76 mm in diameter and 38 mm overall length, it fits into miniature-series drilling operations that demand consistent geometry and tight runout control. Machinists and toolroom technicians are the primary installers of this bit.

This bit is suited for small-diameter drilling in precision machining environments, including CNC drilling centers, manual drill presses, and benchtop machines handling electronics, medical components, instrument housings, and other miniature-scale parts. The 3.00 mm straight-cylindrical shank seats securely in standard collets and drill chucks sized for small-diameter tooling. The regular spiral type supports efficient chip evacuation in short-depth holes typical of this drill diameter.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree point angle for accurate entry and reduced walking on flat surfaces
• Spiral flute geometry promotes chip evacuation in miniature-scale bores
• Bright, uncoated finish allows use across a broad range of workpiece materials
• Right-hand cut with regular spiral type for standard drilling operations
• Straight-cylindrical 3.00 mm shank compatible with standard collets and chucks

Compatibility

Designed as an OEM-style miniature series drill bit for use in standard collet systems and drill chucks accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

This bit is installed and changed by machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the bit from the collet or chuck. Ensure the shank is fully seated and the collet is torqued to the machine manufacturer's specification before operation. Do not exceed the recommended feed and speed parameters for the workpiece material and bit diameter.
