Accupro A-6120165R Micro Drill Bit 1.65mm Solid Carbide

Product Description

The ACCUPRO A-6120165R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 1.65 mm (0.0650 inch) diameter and a 120-degree drill point angle, this bit delivers clean, accurate entry points in hard and abrasive materials. The bright/uncoated finish is suited for applications where coating buildup or interference is a concern. At 38.00 mm overall length with a 2.00 mm straight-cylindrical shank, it fits standard miniature toolholding setups. Machining professionals, toolroom technicians, and precision fabricators working with small-bore requirements rely on this style of bit for consistent performance.

This micro drill bit is intended for small-diameter drilling operations in machining and fabrication environments. The miniature series classification makes it appropriate for circuit board drilling, watchmaking, instrument manufacturing, medical device components, and other applications demanding sub-0.1-inch hole diameters. The right-hand cutting direction and spiral flute configuration are standard for CNC machining centers and benchtop drill presses equipped with appropriate collets or chucks for 2.00 mm shanks.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 1.65 mm (0.0650 inch) drill diameter for precise small-bore applications
• 120-degree point angle for standard entry geometry and reduced walking
• 7.20 mm spiral flute length supports chip evacuation in shallow-to-moderate depth holes
• 2.00 mm straight-cylindrical shank for compatibility with standard miniature collets
• Bright/uncoated finish — no coating buildup, suitable for non-ferrous and ferrous materials

Compatibility

Designed as an OEM-style miniature drill bit for use in CNC machining centers, micro drill presses, and precision toolholding systems accepting a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom technicians familiar with micro-diameter tooling. Ensure the machine spindle and collet are powered down and fully stopped before inserting or removing the bit. Use a collet sized to the 2.00 mm shank diameter — do not over-tighten or use an incompatible chuck style, as micro carbide bits are brittle and susceptible to breakage under lateral load. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before beginning the cut.
