Accupro A-6100174R Micro Drill Bit 1.74 Mm Solid Carbide

Product Description

The ACCUPRO A-6100174R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. At 1.74 mm (0.0685 inches) in diameter, it is built for miniature-series work where accuracy and tool rigidity are critical. The 120-degree drill point angle suits a range of hard and brittle materials. With a 38.00 mm overall length and a 2.00 mm straight-cylindrical shank, this bit fits standard collet chucks and precision drill presses. The bright/uncoated finish provides a clean cutting edge right out of the package. Machinists, toolroom technicians, and precision fabricators are the primary users of this bit.

This micro drill bit is suited for precision machining operations including PCB drilling, instrument component fabrication, watchmaking fixtures, and other small-part production work. The miniature series designation makes it appropriate for CNC machining centers, benchtop drill presses, and manual precision drilling rigs that accept a 2.00 mm straight shank. It performs well in non-ferrous metals, plastics, and other materials where small-diameter hole quality is a priority. The spiral flute design promotes chip evacuation during through-hole operations.

Key Features

• 1.74 mm (0.0685 inches) drill diameter for miniature precision work
• Solid carbide construction for rigidity and wear resistance in small-diameter drilling
• 120-degree standard point angle for general-purpose miniature drilling
• Bright/uncoated finish — no coating buildup that could affect dimensional accuracy
• Straight-cylindrical shank at 2.00 mm fits standard collet chucks and drill presses
• Right-hand cutting direction with regular spiral flutes for consistent chip evacuation

Compatibility

Designed as an OEM-style miniature drill bit for use in precision machining setups that accept a 2.00 mm straight-cylindrical shank. Verify spindle collet or chuck capacity before installation.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the collet or chuck. Secure the shank to the full depth of the collet to prevent pullout during drilling. When working with carbide tooling at this diameter, feed rates and spindle speeds must be set conservatively to avoid tool breakage — consult the machine manufacturer or tooling supplier for appropriate cutting parameters for the target material.
