Accupro A-6100023R Micro Drill Bit Wire 89 Solid Carbide

Product Description

The ACCUPRO A-6100023R is a solid carbide micro drill bit engineered for small-diameter, precision drilling applications. It carries a wire gauge size of 89, equivalent to 0.0091 inches in decimal inch measurement. The 120-degree standard point angle provides accurate entry and reduces walking on hard or smooth surfaces. At 25 mm overall length with a 1.80 mm flute length, this bit is purpose-built for shallow, tight-tolerance holes. The straight-cylindrical shank at 1.00 mm diameter seats securely in collet-style toolholders. Bright uncoated finish suits general-purpose use across a range of work materials. It is installed and used by machinists, tool and die technicians, and precision fabricators working in production or prototype environments.

This micro drill bit fits applications where hole diameter tolerances are extremely tight and standard fractional bits are too large. It is suited for printed circuit board drilling, instrument components, watch and clock parts, small aerospace hardware, and other miniature machined assemblies. Right-hand cut with a regular spiral flute, it performs well in CNC machining centers and manual drill presses equipped with precision collet systems. The miniature series designation indicates it is designed for micro-scale work where repeatability and dimensional accuracy are critical.

Key Features

• Wire gauge size 89 equals 0.0091 inches decimal diameter for precision micro-hole applications
• Solid carbide construction provides hardness and rigidity needed for small-diameter drilling without deflection
• 120-degree standard point angle ensures accurate entry point and clean hole initiation
• Regular spiral flute with right-hand cut supports consistent chip evacuation in miniature bores
• 1.00 mm straight-cylindrical shank fits standard collet toolholders used in precision machining setups
• Bright uncoated finish allows direct inspection of tool condition and suits a broad range of base materials

Compatibility

Designed as an OEM-style replacement or direct-use micro drill bit for miniature series applications requiring a wire size 89 solid carbide drill with a straight-cylindrical shank.

Installation Notes

This bit is installed by machinists and precision tooling technicians using collet-style toolholders rated for the 1.00 mm shank diameter. Ensure the spindle and workpiece are fully secured before beginning the drilling cycle. At this diameter, excessive feed rate or lateral force will cause bit breakage; follow machine manufacturer feed and speed recommendations for solid carbide micro drills. Inspect the cutting edge under magnification before and after use to confirm integrity.
