Accupro A-6120127R Micro Drill Bit 1.27 Mm Solid Carbide

Product Description

The ACCUPRO A-6120127R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a drill diameter of 1.27 mm (0.0500 inches) and a 120-degree drill point angle, this bit produces accurate, clean entry points in hard and abrasive materials. The bright, uncoated finish is suited for applications where coating adhesion or heat buildup is not a primary concern. With an overall length of 30.00 mm and a straight-cylindrical shank diameter of 1.50 mm, it mounts securely in standard collet chucks and precision drill holders used by machinists and toolmakers in production and prototype environments.

This micro drill bit is intended for use in CNC machining centers, benchtop drill presses, and precision hand-held spindle tools where miniature hole drilling is required. The spiral flute geometry and right-hand cutting direction support efficient chip evacuation in metals, plastics, and composites. A 6.00 mm flute length provides adequate cutting depth for most micro-drilling tasks within its size class. It is commonly used in electronics manufacturing, medical device fabrication, watch and instrument repair, and aerospace component work where small, accurate holes are critical.

Key Features

• 1.27 mm (0.0500 inches) drill diameter for miniature precision work
• 120-degree drill point angle for centered, accurate hole starts
• Solid carbide construction for rigidity and wear resistance in hard materials
• Bright, uncoated finish suitable for a wide range of base materials
• Spiral flute, right-hand cutting direction for standard chip evacuation
• Straight-cylindrical shank at 1.50 mm for compatibility with standard micro collet systems

Compatibility

Designed as an OEM-style replacement and general-purpose micro drill bit for use in CNC spindles, benchtop drill presses, and precision rotary tools accepting a 1.50 mm straight-cylindrical shank.

Installation Notes

Installation is performed by machinists or toolroom technicians. Secure the shank fully in the collet or chuck and verify runout before drilling. Ensure the workpiece is clamped rigidly to prevent deflection at this diameter. Coolant through is not supported on this bit, so external coolant or cutting fluid should be applied where required by the workpiece material.
