Accupro A-6100175R Micro Drill Bit 1.75 Mm Solid Carbide

Product Description

The ACCUPRO A-6100175R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a 1.75 mm (0.0689 inch) cutting diameter and a 120-degree drill point angle, this bit delivers accurate hole placement and clean entry in hard and abrasive materials. The straight-cylindrical shank measures 2.00 mm in diameter, and the overall length is 38.00 mm with a 12.00 mm flute length. The bright, uncoated finish is standard for solid carbide tooling where coating is not required. Machinists and toolroom technicians install this bit in CNC machining centers, drill presses, and precision hand-held fixtures handling small-diameter work.

This micro drill bit is suited for precision machining operations in electronics, medical device manufacturing, aerospace component work, and any application requiring consistent small-diameter holes. The miniature series designation indicates it is engineered for sub-2 mm diameter drilling where standard jobber-length bits are not appropriate. Right-hand cutting direction is standard for conventional spindle rotation. Spiral flutes with a regular spiral type support chip evacuation in short-flute micro drilling conditions.

Key Features

• 1.75 mm (0.0689 inch) drill diameter for tight-tolerance micro hole applications
• Solid carbide construction provides rigidity and wear resistance in hard materials
• 120-degree drill point angle for standard entry geometry
• Straight-cylindrical 2.00 mm shank for compatibility with standard collet chucks and micro drill chucks
• 12.00 mm flute length and 38.00 mm overall length suit miniature series work envelopes
• Bright uncoated finish — no coating risk of edge buildup in sensitive micro drilling operations

Compatibility

Designed as an OEM-style replacement and standard production micro drill bit for machining setups requiring a 1.75 mm straight-shank solid carbide drill in the miniature series class.

Installation Notes

Installation is performed by machinists or toolroom technicians familiar with precision CNC or manual drilling equipment. Secure the straight-cylindrical shank in an appropriately sized collet or micro drill chuck rated for the spindle speed required for the workpiece material. Confirm runout on the shank before starting a new drilling operation, as micro-diameter carbide bits are sensitive to lateral load. Do not use this bit in impact-type drivers or non-precision chucks that cannot hold shank concentricity.
