Accupro A-6120161R Size 52 Solid Carbide Micro Drill Bit

Product Description

The ACCUPRO A-6120161R is a solid carbide micro drill bit designed for precision drilling in tight tolerances and small-diameter applications. Sized at wire gauge 52 (0.0634 inches / 1.61 mm), it features a 120-degree standard point angle and a spiral flute geometry with a regular spiral type for consistent chip evacuation. The straight-cylindrical shank measures 2.00 mm in diameter and the overall length is 38.00 mm. This bit ships in a bright, uncoated finish with no coolant-through capability. It is suited for machinists, toolmakers, and precision fabricators working in metalworking, electronics, and instrument manufacturing environments.

The A-6120161R is a miniature-series drill bit intended for applications requiring very small bore diameters, such as drilling pilot holes, electrical component boards, instrument housings, and precision machined parts. The right-hand cutting direction makes it compatible with conventional CNC machining centers, drill presses, and hand-held precision drilling tools with standard right-hand spindle rotation. The solid carbide construction makes it well suited for harder materials where high-speed steel bits would deflect or wear prematurely.

Key Features

• Wire gauge size 52 (1.61 mm / 0.0634 inches) for precision small-diameter drilling
• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree standard point angle for accurate self-centering on entry
• Spiral flute with regular spiral type promotes efficient chip evacuation
• Bright, uncoated finish — no coating buildup risk on close-tolerance diameters
• Straight-cylindrical shank for secure clamping in standard collets and chucks

Compatibility

Designed as an OEM-style miniature series drill bit compatible with CNC machining centers, drill presses, and precision drilling equipment that accept a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation and use of this drill bit should be performed by qualified machinists or toolroom professionals. Ensure the spindle and workpiece are fully secured before initiating the drilling cycle. For micro-diameter carbide tooling, use appropriate spindle speeds and feed rates per material manufacturer recommendations to avoid bit fracture. Inspect the cutting edge for chipping before each use, as carbide micro drills are brittle and sensitive to side-loading or excessive runout in the chuck.
