Accupro A-6120237R Micro Drill Bit 2.37mm Solid Carbide

Product Description

The ACCUPRO A-6120237R is a solid carbide micro drill bit engineered for precision drilling in tight-tolerance applications. It measures 2.37 mm in diameter (0.0933 inches) with an overall length of 38 mm (1.496 inches) and a flute length of 12 mm (0.472 inches). The 120-degree point angle provides accurate centering and clean entry, while the bright, uncoated finish is suited for use in a wide range of materials. The straight-cylindrical shank measures 3.00 mm in diameter, making it compatible with standard collet and chuck setups. This bit is designed for machinists, toolmakers, and precision fabricators working in production or job-shop environments.

The A-6120237R is used in applications where small-diameter, high-accuracy holes are required. Its miniature series designation makes it appropriate for drilling circuit board components, instrument housings, small mechanical assemblies, and precision fixtures. Right-hand cutting geometry and a regular spiral flute type promote efficient chip evacuation in both ferrous and non-ferrous materials. This bit is sold individually, with a minimum order quantity of 10 units per purchase.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision drilling
• 2.37 mm (0.0933 inch) diameter with a 3.00 mm straight-cylindrical shank
• 120-degree standard point angle for accurate self-centering entry
• 12 mm spiral flute length promotes chip clearing in shallow to medium-depth holes
• Bright/uncoated finish — no thermal barrier to manage, suitable for a broad material range
• Right-hand cut, regular spiral flute for consistent performance in production runs

Compatibility

Designed as an OEM-style miniature series drill bit compatible with standard collet chucks and drill presses accepting a 3.00 mm straight-cylindrical shank.

Installation Notes

Installation of this drill bit should be performed by a qualified machinist or toolroom technician. Secure the straight shank firmly in a collet or drill chuck rated for the shank diameter before operation. Ensure spindle speed and feed rate are appropriate for solid carbide tooling and the workpiece material. Do not use this bit in a hammer-drill mode or any application involving lateral loading, as carbide is brittle under bending stress.
