Accupro A-6120254R Micro Drill Bit 2.54 Mm Solid Carbide

Product Description

The ACCUPRO A-6120254R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Built from solid carbide, it delivers the rigidity and wear resistance needed when drilling small-diameter holes in hard or abrasive materials. The bit features a 120-degree point angle, a spiral flute geometry with regular spiral type, and a bright uncoated finish. At 2.54 mm in diameter and 38 mm overall length, with a 14 mm flute length, this bit fits the miniature series category and is well suited for machinists, toolmakers, and precision fabricators working with CNC machines, drill presses, or manual spindles requiring micro-diameter tooling.

This drill bit is intended for use in precision machining environments where small hole diameters and accurate positioning are critical. Typical applications include electronic component manufacturing, instrument fabrication, mold and die work, and other operations requiring sub-millimeter to low-millimeter hole sizes. The right-hand cutting direction and straight-cylindrical shank make it compatible with standard collet chucks and drill chucks commonly found on machining centers and bench-top drill presses. The 3.00 mm shank diameter provides secure tool holding in appropriately sized collets.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• 120-degree standard point angle for accurate hole entry and reduced walking
• Spiral flute with regular helix promotes chip evacuation in micro-diameter drilling
• Bright uncoated finish suitable for non-ferrous metals, plastics, and composites
• Straight-cylindrical shank fits standard collet chucks and drill chucks
• Right-hand cut, no coolant-through requirement simplifies setup

Compatibility

Designed as a miniature-series micro drill bit for use in standard collet chucks and drill chucks that accept a 3.00 mm straight-cylindrical shank, suitable for CNC machining centers, drill presses, and precision benchtop equipment.

Installation Notes

Installation and tool changes should be performed with the spindle fully stopped and the machine in a locked-out state per applicable shop safety procedures. Secure the straight-cylindrical shank in a properly sized collet or chuck to the chuck manufacturer's recommended torque before operation. Verify spindle speed is appropriate for the workpiece material and 2.54 mm diameter before initiating the cut. Micro drill bits are brittle — avoid side loading, excessive feed pressure, or use in worn or runout-prone chucks.
