Accupro A-6120160R Micro Drill Bit 1.6 Mm Solid Carbide

Product Description

The ACCUPRO A-6120160R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. It features a 1.6 mm (0.0630 inch) diameter, a 120-degree standard point angle, and a spiral flute configuration for efficient chip evacuation. The straight-cylindrical shank measures 2.0 mm in diameter, and the overall length is 38.0 mm with a flute length of 7.2 mm. The bright, uncoated finish maintains close dimensional tolerances straight from the grind. This bit is suited for machinists, toolmakers, and precision fabricators working with small-diameter hole requirements in production or prototype environments.

This micro drill bit is built for use in CNC machining centers, drill presses, and precision hand-piece equipment where small-diameter accuracy is critical. It is part of the Miniature Series, intended for applications in electronics manufacturing, medical device fabrication, instrumentation, and other industries requiring holes in the sub-2 mm range. Right-hand cut geometry is standard for conventional spindle rotation. No coolant-through capability is present, so external coolant or dry cutting methods apply depending on material and feed conditions.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• 1.6 mm (0.0630 inch) drill diameter with 120-degree standard point angle
• Spiral flute, regular spiral type for consistent chip removal in miniature bores
• Bright, uncoated finish — no coating buildup affecting diameter tolerance
• Straight-cylindrical shank, 2.0 mm diameter for secure collet holding
• Right-hand cut, compatible with standard spindle rotation

Compatibility

Designed as an OEM-style miniature series drill bit for use in collet chucks and precision drill holders accepting a 2.0 mm straight-cylindrical shank.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully in a properly sized collet or chuck before operation and verify runout with an indicator before production use. Do not exceed manufacturer-recommended feed and speed parameters for solid carbide tooling in the target material. Inspect the cutting edges under magnification before each use — micro drill bits are susceptible to chipping at small diameters and should not be run if edge damage is present.
