Accupro A-6100126R Micro Drill Bit 1.26 Mm Solid Carbide

Product Description

The ACCUPRO A-6100126R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a cutting diameter of 1.26 mm (0.0496 inches) and a 120-degree drill point angle, it delivers accurate, clean entry in hard and abrasive materials where smaller tooling is required. The bright, uncoated finish suits applications where coating interference is a concern or where post-process inspection is needed. An overall length of 30.00 mm and a straight-cylindrical shank diameter of 1.50 mm make it compatible with standard micro drill chucks and collet holders. This bit is sold individually but requires a minimum order of 10 units.

The A-6100126R is suited for precision machining, PCB fabrication, instrument manufacturing, and other applications that demand tight hole tolerances at small diameters. The spiral flute geometry promotes chip evacuation during drilling, which is critical when working with close-tolerance bores in metals, composites, or engineering plastics. Its miniature series classification makes it a go-to choice for machinists, toolmakers, and production operators working on fine-detail components where standard drill sizes are too large.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• 1.26 mm (0.0496 inches) cutting diameter for precision micro-hole applications
• 120-degree standard point angle for accurate self-centering on entry
• Spiral flute design promotes efficient chip evacuation during drilling
• Straight-cylindrical shank (1.50 mm) fits standard micro collets and chucks
• Bright, uncoated finish suitable for applications where coated tooling is not preferred

Compatibility

Designed for use in CNC machining centers, drill presses, and precision hand-held drilling equipment equipped with collets or chucks accepting a 1.50 mm straight-cylindrical shank.

Installation Notes

Installation and use should be performed by qualified machinists or toolroom professionals familiar with micro-diameter tooling. Ensure the spindle and collet are clean and free of debris before seating the shank, as runout at this diameter scale has a significant effect on hole quality and tool life. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material. Micro drill bits are brittle at this diameter and should not be used to ream or side-load the cutting edge.
