Accupro A-6120162R Micro Drill Bit 1.62 Mm Solid Carbide

Product Description

The ACCUPRO A-6120162R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. Measuring 1.62 mm (0.0638 inches) in diameter with a 120-degree drill point angle, this bit delivers accurate, clean entry points in tight-tolerance work. The bright/uncoated finish is suited for materials where coating adhesion is not required. With an overall length of 38.00 mm and a straight-cylindrical shank measuring 2.00 mm in diameter, the bit fits standard miniature toolholders used in precision machining environments. It is installed and operated by machinists, toolmakers, and precision fabricators working on micro-scale components.

This drill bit is part of the ACCUPRO Miniature Series, intended for applications that demand small-diameter drilling with tight tolerances. Typical use cases include printed circuit board fabrication, instrument manufacturing, medical device components, and other precision machining tasks where conventional drill sizes are too large. The right-hand cutting direction and spiral flute design work together to evacuate chips efficiently during through-hole and blind-hole drilling operations. It is sold individually with a minimum order quantity of 10 units.

Key Features

• 1.62 mm (0.0638 inches) drill diameter for micro-scale precision drilling
• Solid carbide construction provides rigidity and wear resistance in small-diameter cutting
• 120-degree drill point angle for standard entry geometry
• Bright/uncoated finish — no coating buildup in critical tolerance applications
• Spiral flute, right-hand cut for efficient chip evacuation
• Straight-cylindrical shank compatible with standard miniature collets and chucks

Compatibility

Designed as an OEM-style replacement and standard tooling option for miniature drill applications using straight-cylindrical shank toolholders sized for 2.00 mm shanks.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always ensure the machine spindle is fully stopped and the toolholder is clean and free of debris before seating the bit. Secure the 2.00 mm straight-cylindrical shank in a collet or chuck rated for miniature tooling to prevent runout. Do not exceed the recommended feed and speed parameters for solid carbide micro drills, as solid carbide is rigid but brittle at very small diameters and is susceptible to breakage from lateral loading or improper feeds.
