Accupro A-6120053R Micro Drill Bit Wire 75 Solid Carbide

Product Description

The ACCUPRO A-6120053R is a micro drill bit designed for precision drilling in tight-tolerance applications. Built from solid carbide, it delivers the rigidity and wear resistance required for drilling small-diameter holes through hard materials. The bit features a 120-degree point angle, a spiral flute with right-hand cut, and a bright/uncoated finish. With an overall length of 25 millimeters and a shank diameter of 1.00 millimeter, this bit fits the miniature series and handles wire gauge size 75, corresponding to a decimal diameter of 0.0209 inches. It is suited for machinists, toolmakers, and precision fabricators working in production or prototype environments.

This micro drill bit is used in applications requiring extremely small hole diameters, such as circuit board drilling, watch and instrument components, medical device manufacturing, and fine metalwork. The straight-cylindrical shank seats securely in standard collets and precision chucks sized for 1.00 millimeter shanks. The spiral flute geometry promotes chip evacuation in shallow to moderate depth holes. The right-hand cutting direction is standard for conventional CNC and manual spindle operation.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard materials
• Wire gauge size 75 with a decimal diameter of 0.0209 inches
• 120-degree standard point angle for accurate entry and reduced walking
• Spiral flute, right-hand cut for conventional spindle use
• Bright/uncoated finish suitable for a wide range of workpiece materials
• Straight-cylindrical shank with 1.00 millimeter diameter for secure collet seating

Compatibility

Designed as an OEM-style miniature series micro drill bit compatible with precision collets and chucks accepting a 1.00 millimeter straight-cylindrical shank.

Installation Notes

Installation and use of this bit should be performed by a qualified machinist or toolroom technician. Verify spindle runout is within tolerance before use, as excess runout at this diameter will cause premature breakage. Secure the shank fully in the collet and confirm concentricity before starting the cut. Follow shop safety procedures and machine guarding requirements at all times when operating rotating cutting tools.
