Accupro A-6100176R Micro Drill Bit 1.76 Mm Solid Carbide

Product Description

The ACCUPRO A-6100176R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. Measuring 1.76 mm (0.0693 inches) in diameter with a 2.00 mm straight-cylindrical shank, this bit delivers the rigidity and dimensional accuracy that machining professionals require at the micro scale. The 120-degree drill point angle suits a wide range of materials, while the bright, uncoated finish preserves the full hardness of the carbide substrate. With an overall length of 38.00 mm and a flute length of 12.00 mm, it fits standard miniature-series toolholders used in CNC machining centers and manual drill presses alike.

This bit is suited for precision micro-drilling operations in metalworking, electronics manufacturing, medical device fabrication, and general machining environments. The right-hand cutting direction and regular spiral flute geometry promote consistent chip evacuation in small-diameter holes. It is intended for use by machinists, tool-and-die makers, and precision manufacturing technicians working in both production and prototype settings. The miniature series designation places it in standard tooling inventories for facilities requiring sub-2 mm drill capability.

Key Features

• Solid carbide construction for maximum hardness and wear resistance at micro diameters
• 1.76 mm drill diameter with 2.00 mm straight-cylindrical shank for secure chuck engagement
• 120-degree standard point angle for reliable entry and reduced walking on flat surfaces
• Bright, uncoated finish retains full carbide substrate hardness without added coating thickness
• Regular spiral flute with right-hand cutting direction for consistent chip evacuation
• 38.00 mm overall length with 12.00 mm flute length suits miniature-series toolholders

Compatibility

Designed as an OEM-style miniature series micro drill bit compatible with standard straight-cylindrical chuck and collet systems accepting a 2.00 mm shank diameter.

Installation Notes

Micro drill bits should be installed and removed by a qualified machinist with the spindle fully powered down and locked. Secure the 2.00 mm shank in a precision collet or keyless chuck rated for miniature tooling to minimize runout. Avoid side-loading or flexing the bit during setup, as solid carbide is brittle at small diameters and will fracture under lateral stress. Verify spindle speed and feed rate against the material being drilled before beginning the operation.
