Accupro A-6120230R Micro Drill Bit 2.30mm Solid Carbide

Product Description

The ACCUPRO A-6120230R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 2.30 mm (0.0906 inch) cutting diameter and a 120-degree drill point angle, this bit delivers clean, accurate entry points in hard and abrasive materials where standard high-speed steel tooling falls short. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length comes in at 38.00 mm, keeping the tool compact for confined-space drilling setups. The bright/uncoated finish makes it easy to inspect the cutting edge for wear. Machinists, toolmakers, and precision fabricators working on small-diameter hole applications rely on this style of micro drill for consistent performance.

This miniature series drill bit is suited for precision machining operations on ferrous metals, non-ferrous alloys, and engineered plastics where hole diameter control is critical. Typical applications include instrument components, medical device subassemblies, electronics housings, and fixture work requiring sub-3 mm bore diameters. The 12.00 mm flute length provides adequate chip evacuation for shallow-to-moderate depth holes in the 2.30 mm range. The right-hand cutting direction pairs with standard CNC machining centers, benchtop drill presses, and precision hand-piece spindles running conventional rotation.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• 2.30 mm (0.0906 inch) cutting diameter for tight-tolerance micro-hole applications
• 120-degree drill point angle for controlled entry and reduced walking on hard surfaces
• Straight-cylindrical 3.00 mm shank for secure chuck retention on standard collets and Jacobs-style chucks
• Spiral flute geometry with regular spiral type promotes consistent chip evacuation
• Bright/uncoated finish allows straightforward visual inspection of cutting edge condition

Compatibility

Designed as an OEM-style miniature drill bit for use in standard 3.00 mm straight-cylindrical collet chucks and compatible CNC machining centers, benchtop drill presses, or precision spindle units accepting straight-shank tooling in the micro-drill range.

Installation Notes

A licensed machinist or trained toolroom technician should seat and torque the shank securely in a clean, matched collet or chuck before use. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Do not exceed the recommended feed and speed parameters for the work material and drill diameter. Inspect the cutting edge for chipping or wear before each use, as solid carbide micro drills are brittle and sensitive to side-load or run-out.
