Accupro A-6200230R Micro Drill Bit 2.30mm Solid Carbide

Product Description

The ACCUPRO A-6200230R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. Built to the Miniature Series standard, it features a 2.30 mm (0.0906 inch) cutting diameter, a 140-degree drill point angle, and a bright/uncoated finish. The straight-cylindrical shank measures 3.00 mm in diameter, and the overall length is 50.00 mm. The spiral flute geometry promotes chip evacuation in tight bores. This bit is suited for machinists, toolmakers, and precision fabricators working with small-diameter holes in ferrous and non-ferrous materials.

This micro drill bit is intended for use in CNC machining centers, drill presses, and precision hand-held equipment where small-diameter, accurate bore entry is required. The miniature form factor makes it appropriate for electronics enclosures, instrumentation components, medical device fixtures, and other close-tolerance fabrication work. The right-hand cutting direction is standard for conventional spindle rotation. No coolant-through capability is present, so external coolant or cutting fluid application is recommended when drilling harder materials.

Key Features

• 2.30 mm (0.0906 inch) cutting diameter for precision small-bore work
• Solid carbide construction for rigidity and wear resistance in hard materials
• 140-degree drill point angle reduces thrust and improves centering
• Bright/uncoated finish — compatible with a wide range of workpiece materials
• Spiral flute, straight-cylindrical shank for secure chuck or collet holding
• 16.50 mm flute length with 50.00 mm overall length

Compatibility

Designed for use in standard collets and drill chucks accepting a 3.00 mm straight-cylindrical shank. Suitable for CNC machining centers, benchtop drill presses, and precision rotary tools configured for miniature-series carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully and evenly in the collet or chuck to minimize runout, which is critical at small diameters. Because this bit has no coolant-through capability, apply external cutting fluid appropriate for the workpiece material to extend tool life and reduce heat buildup.
