Accupro A-6120119R Micro Drill Bit 3/64 Inch Solid Carbide

Product Description

The ACCUPRO A-6120119R is a miniature series solid carbide micro drill bit designed for high-precision drilling in tight-tolerance applications. It features a 3/64 inch (0.0469 inch / 1.19 mm) diameter, a 120-degree drill point angle, and a bright uncoated finish. The straight-cylindrical shank measures 1.50 mm in diameter, and the overall length is 30.00 mm. Built from solid carbide, this bit delivers the rigidity and wear resistance required when drilling small-diameter holes in ferrous and non-ferrous materials. It is sold individually with a minimum order quantity of 10 units.

This micro drill bit is suited for precision machining environments where small-diameter hole accuracy is critical. Typical applications include circuit board drilling, instrument components, medical device parts, and fine-tolerance metalwork. The right-hand cutting direction and spiral flute geometry support clean chip evacuation in shallow-to-moderate depth holes. The miniature series designation makes it a standard choice for machinists and toolroom professionals working on small-part production or prototype work in CNC or manual drill press setups.

Key Features

• Solid carbide construction for rigidity and extended tool life in small-diameter drilling
• 3/64 inch (0.0469 inch / 1.19 mm) cutting diameter for tight-tolerance hole requirements
• 120-degree standard point angle for accurate entry and reduced walking
• Bright uncoated finish compatible with a wide range of workpiece materials
• Straight-cylindrical shank (1.50 mm) for secure chuck retention
• Right-hand spiral flute geometry promotes efficient chip evacuation

Compatibility

Designed as an OEM-style miniature drill bit for use in standard straight-shank collets and drill chucks accepting 1.50 mm shank diameters on CNC machining centers, drill presses, and precision hand-held drilling equipment.

Installation Notes

Micro drill bits of this diameter should be installed by a machinist or toolroom professional using a properly sized collet or drill chuck rated for 1.50 mm straight shanks. Ensure the spindle and workpiece are fully secured before starting the cut to prevent bit deflection or breakage. Avoid applying excessive feed pressure — micro carbide bits are brittle and will snap under lateral load or aggressive feed rates. Always follow applicable machine shop safety practices and equipment manufacturer guidelines when operating at high spindle speeds.
