Accupro A-6120222R Micro Drill Bit 2.22mm Solid Carbide

Product Description

The ACCUPRO A-6120222R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Measuring 2.22 mm in diameter (0.0874 inches decimal equivalent) with a 120-degree point angle, this bit is built for accurate entry and minimal walking on hard or abrasive workpiece materials. The bright, uncoated finish makes it easy to inspect for wear. With an overall length of 38 mm and a spiral flute design, it delivers consistent chip evacuation in small-diameter bores. It is suited for machinists, toolmakers, and precision fabricators working on CNC machines, drill presses, or manual milling setups requiring miniature-series tooling.

This micro drill bit fits applications where small-diameter, high-precision holes are required in materials such as metals, composites, or plastics. The straight-cylindrical shank with a 3.00 mm diameter seats securely in standard collets and chucks used in CNC machining centers, manual mills, and benchtop drill presses. Right-hand cut and regular spiral flute geometry make it compatible with conventional clockwise-spindle machines common in production and job-shop environments.

Key Features

• 2.22 mm diameter with 0.0874 inch decimal equivalent for precise hole sizing
• 120-degree standard point angle for accurate entry and reduced thrust load
• Solid carbide construction for rigidity and wear resistance in hard materials
• Bright, uncoated finish allows easy visual wear inspection
• Spiral flute geometry promotes chip evacuation in small-diameter bores
• Straight-cylindrical 3.00 mm shank fits standard collets and drill chucks

Compatibility

Designed as an OEM-style miniature-series replacement drill bit for use in standard collets and chucks accepting a 3.00 mm straight-cylindrical shank on CNC machining centers, manual mills, and benchtop drill presses.

Installation Notes

This bit should be installed and removed by a qualified machinist following standard toolholding procedures for miniature-series carbide tooling. Ensure the spindle is fully powered down and locked before changing tooling. Carbide is brittle — avoid lateral loading or prying, as this can chip the cutting edge. Confirm runout and chuck grip before beginning a drilling cycle to prevent premature breakage.
