Accupro A-6100177R Micro Drill Bit 1.77 Mm Solid Carbide

Product Description

The ACCUPRO A-6100177R is a miniature series solid carbide micro drill bit engineered for precision drilling in small-diameter applications. It measures 1.77 mm (0.0697 inches) in diameter with a 38 mm overall length and a 12 mm flute length. The 120-degree point angle delivers accurate self-centering entry, while the spiral flute geometry promotes chip evacuation in tight bores. The bright, uncoated finish is suited for general-purpose use across a range of workpiece materials. Machinists, toolroom technicians, and precision fabricators install this bit in CNC machining centers, drill presses, and handheld precision spindles where tight tolerances and small hole diameters are required.

This micro drill bit is designed for miniature drilling operations in electronics manufacturing, medical device fabrication, instrument assembly, and precision metalworking. Its 2.00 mm straight-cylindrical shank fits standard collets and chucks sized for miniature tooling. Right-hand cutting direction is compatible with standard machine spindle rotation. Applications include drilling pilot holes, through holes, and clearance holes in ferrous and non-ferrous metals, plastics, and composite materials where small diameters and close tolerances are critical.

Key Features

• 1.77 mm (0.0697 inch) drill diameter for precision miniature hole sizing
• Solid carbide construction provides rigidity and wear resistance in hard materials
• 120-degree standard point angle for accurate entry and reduced walking
• Spiral flute geometry supports chip evacuation in deep or blind holes
• Bright/uncoated finish suitable for general-purpose miniature drilling
• Straight-cylindrical 2.00 mm shank fits standard miniature collets and chucks

Compatibility

Designed for use in CNC machining centers, benchtop drill presses, and precision spindle units equipped with collets or chucks accepting a 2.00 mm straight-cylindrical shank in the miniature tooling series.

Installation Notes

This bit is installed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the shank fully in the collet or chuck to the recommended engagement depth for the tool holder in use. Avoid side-loading micro diameter carbide bits, as carbide is brittle and susceptible to breakage under lateral force.
