Accupro A-6120224R Micro Drill Bit 2.24 Mm Solid Carbide

Product Description

The ACCUPRO A-6120224R is a solid carbide micro drill bit designed for small-diameter precision drilling in metalworking, machining, and fabrication applications. At 2.24 mm (0.0882 inches) in diameter, it features a 120-degree point angle and a spiral flute geometry that promotes clean chip evacuation in tight bore conditions. The bright, uncoated carbide construction delivers hardness and wear resistance suited to high-speed drilling in ferrous and non-ferrous materials. With an overall length of 38 mm and a 3.00 mm straight-cylindrical shank, this bit fits standard collet chucks and drill presses used by machinists and tool-and-die professionals.

This micro drill bit is built for precision work where close tolerances and small hole diameters are required. It is well suited to CNC machining centers, manual milling machines, and bench drill presses in job shops, manufacturing facilities, and maintenance environments. The miniature series designation indicates it is intended for fine, detailed drilling tasks rather than general-purpose production drilling. Right-hand cutting direction is standard for conventional drill press and CNC spindle rotation.

Key Features

• 2.24 mm diameter with 0.0882 inch decimal equivalent for cross-reference
• 120-degree point angle for standard material entry and self-centering
• Solid carbide construction for hardness and dimensional stability
• Bright, uncoated finish — no coating buildup to affect tight tolerances
• Spiral flute with right-hand cut for efficient chip removal
• Straight-cylindrical 3.00 mm shank fits standard collets and chucks

Compatibility

Designed as an OEM-style miniature series micro drill bit compatible with standard straight-shank collet chucks, ER collet systems, and drill press chucks accepting a 3.00 mm shank diameter.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals familiar with small-diameter carbide tooling. Secure the shank fully in the collet or chuck before operation to prevent runout, which can cause carbide breakage at small diameters. Use appropriate spindle speeds and feed rates for the material being drilled — carbide micro drills are brittle and prone to fracture under side load or excessive feed pressure. Inspect the cutting edges before each use and replace the bit if chipping or wear is observed.
