Accupro A-6200225R Micro Drill Bit 2.25 Mm Solid Carbide

Product Description

The ACCUPRO A-6200225R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. It measures 2.25 mm in diameter with a 50 mm overall length and features a 140-degree split point that reduces walking and allows for accurate entry without a center punch. The spiral flute geometry promotes efficient chip evacuation during drilling. This bit is suited for machinists, toolmakers, and precision fabricators working in tight tolerances on hard or abrasive materials where high-speed steel tooling falls short.

This micro drill bit is used in CNC machining centers, drill presses, and manual precision work where small-diameter holes are required. It is appropriate for drilling metals, composites, and other hard materials common in aerospace, electronics, and general precision manufacturing. The straight-cylindrical shank with a 3.00 mm shank diameter seats cleanly in standard collets and chucks. It is sold individually with a minimum order quantity of 10 units.

Key Features

• 2.25 mm drill diameter with 0.0886 decimal inch equivalent for cross-reference
• 140-degree standard point angle for accurate entry and reduced thrust
• Solid carbide construction for rigidity and wear resistance in hard materials
• Bright/uncoated finish suitable for general-purpose precision drilling
• Spiral flute with right-hand cut for efficient chip removal
• 3.00 mm straight-cylindrical shank for compatibility with standard collets and chucks

Compatibility

Designed for use in standard collet chucks and drill chucks accepting a 3.00 mm straight-cylindrical shank, as found on CNC machining centers and precision benchtop drill presses used in small-diameter drilling applications.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with small-diameter tooling. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Secure the shank fully in the collet or chuck to the recommended grip depth to minimize runout and prevent bit breakage. Micro drill bits are susceptible to breakage under side load or excessive feed pressure — use appropriate feed and speed parameters for the workpiece material.
