Accupro A-6100162R Micro Drill Bit 1.62mm Solid Carbide

Product Description

The ACCUPRO A-6100162R is a solid carbide micro drill bit designed for precision drilling in small-diameter applications. It measures 1.62 mm (0.0638 inches) in diameter with an overall length of 38 mm and a 120-degree standard point angle. The spiral flute geometry promotes efficient chip evacuation, and the bright, uncoated finish suits a wide range of materials without introducing coating-related dimensional variation. This bit is suited for machinists, toolroom technicians, and production drilling operators working in tight-tolerance environments.

This drill bit fits applications requiring accurate, repeatable small-diameter holes in metal, plastic, or composite workpieces. The straight-cylindrical shank with a 2 mm shank diameter seats securely in standard collets and chucks. The miniature series designation indicates it is built for micro and precision drilling operations common in instrument manufacturing, electronics assembly, medical device fabrication, and similar precision machining contexts.

Key Features

• 1.62 mm diameter with 0.0638 inch decimal equivalent for cross-reference
• 120-degree standard point angle for accurate hole entry and reduced walking
• Solid carbide construction for rigidity and wear resistance in precision drilling
• Spiral flute with regular spiral type promotes chip evacuation in through and blind holes
• Bright, uncoated finish maintains nominal dimensions without coating buildup
• Right-hand cut, straight-cylindrical shank for compatibility with standard collet and chuck setups

Compatibility

Designed for use in CNC machining centers, drill presses, and precision hand-held drilling equipment accepting a 2 mm straight-cylindrical shank in miniature series tooling setups.

Installation Notes

This bit should be installed by qualified machinists or toolroom personnel familiar with micro drill handling. Secure the shank fully in the collet or chuck and verify runout before drilling. Use appropriate spindle speeds and feeds for carbide tooling in the workpiece material to prevent bit breakage. Avoid side loading or flexing the bit during operation, as micro carbide tooling is brittle under lateral force.
