Accupro A-6120225R Micro Drill Bit 2.25 Mm Solid Carbide

Product Description

The ACCUPRO A-6120225R is a solid carbide micro drill bit designed for precision small-diameter drilling in tight-tolerance applications. Built to 2.25 mm diameter (0.0886 inch decimal equivalent), it features a 120-degree point angle that promotes accurate entry and reduces walking on hard or smooth surfaces. The bright uncoated finish keeps the cutting edge sharp and is well suited for drilling non-ferrous metals, plastics, composites, and similar materials. At 38 mm overall length with a 12 mm flute length, this bit fits standard miniature-series toolholders and is appropriate for CNC drilling centers, drill presses, and manual precision work where small hole diameters are required.

This bit is used in manufacturing, prototype fabrication, PCB drilling, instrument assembly, and other precision machining environments where hole diameters under 3 mm are common. The straight-cylindrical shank at 3.00 mm diameter seats reliably in standard collets and chucks. The right-hand spiral flute geometry evacuates chips effectively during through-hole and blind-hole operations. It is sold individually with a minimum order quantity of 10 units, making it practical for shop stock replenishment or toolroom inventory.

Key Features

• 2.25 mm diameter with 0.0886 inch decimal equivalent for tight-tolerance hole sizing
• Solid carbide construction provides rigidity and wear resistance in hard and abrasive materials
• 120-degree standard point angle reduces drill wander at entry
• Right-hand cut with regular spiral flute for efficient chip evacuation
• Bright uncoated finish suitable for non-ferrous metals, plastics, and composites
• Straight-cylindrical 3.00 mm shank fits standard miniature-series collets and chucks

Compatibility

Designed for use in standard miniature-series drill toolholders and collet chucks accepting a 3.00 mm straight-cylindrical shank, common in CNC machining centers and precision drill presses.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom personnel familiar with small-diameter carbide tooling. Ensure the machine spindle and toolholder are clean and free of runout before seating the shank, as carbide micro drills are brittle and sensitive to side loading. Power down and lock out the machine before changing tooling. Use appropriate feeds and speeds for the workpiece material, as carbide micro drills can fracture if feed rates are too aggressive or the setup is not rigid.
