The ACCUPRO A-6120243R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. The bit measures 2.43 mm in diameter with an overall length of 38 mm and a flute length of 12 mm. It features a 120-degree point angle and a spiral flute configuration for efficient chip evacuation. The bright, uncoated finish maintains tight dimensional tolerances straight from the manufacturer. This bit is typically installed by machinists, toolmakers, and precision fabricators working on close-tolerance components in metal or composite materials.
This micro drill bit is suited for small-bore drilling operations in manufacturing, tooling, and precision machining environments. The straight-cylindrical shank with a 3 mm diameter provides consistent clamping in standard drill chucks and collet holders. The right-hand cut direction and regular spiral type make it compatible with conventional CNC and manual drilling setups. Applications include circuit board drilling, instrument components, and other work requiring sub-3 mm hole diameters with controlled entry geometry.
Designed as an OEM-style miniature series drill bit compatible with standard collet systems and drill chucks that accept a 3 mm straight-cylindrical shank diameter.
This bit is installed by qualified machinists or toolroom technicians. Secure the shank fully in a collet or drill chuck rated for the intended spindle speed before operation. Ensure the machine spindle is fully stopped and de-energized before bit changes. Do not use in left-hand or reverse-rotation spindle setups, as this is a right-hand cut tool.
