Accupro A-6100024R Micro Drill Bit Size 88 0.0094 in Carbide

Product Description

The ACCUPRO A-6100024R is a solid carbide micro drill bit engineered for precision drilling at extremely small diameters. Sized at wire gauge 88, this bit measures 0.0094 inches in diameter with a 120-degree drill point angle. The uncoated bright finish and straight-cylindrical shank are suited for controlled entry in tight-tolerance applications. Overall length is 25.00 mm with a 1.80 mm flute length and a 1.00 mm shank diameter. Right-hand cutting direction with a regular spiral and standard point type make this bit a reliable choice for machinists and precision fabricators working in metals, printed circuit boards, and similar fine-tolerance materials.

This micro drill bit is used in applications that demand small-diameter, high-precision holes. Typical scenarios include PCB drilling, instrument manufacturing, watchmaking components, medical device fabrication, and other miniature machining work. The miniature series designation indicates it is purpose-built for setups where conventional drill bits are too large. It is installed in precision drill presses, CNC machining centers, or hand-held micro drill units configured for small-shank tooling. No coolant-through capability is present, so external or flood cooling should be planned when drilling heat-sensitive substrates.

Key Features

• Wire gauge 88 diameter at 0.0094 inches for ultra-fine hole production
• 120-degree drill point angle reduces walking on hard, smooth surfaces
• Solid carbide construction provides hardness and wear resistance over high-speed steel alternatives
• Bright uncoated finish compatible with a wide range of base materials without coating interference
• Regular spiral flute type supports consistent chip evacuation in shallow micro-drilling passes
• Straight-cylindrical shank fits standard micro collets and precision chucks

Compatibility

Designed for use in precision machining setups accepting a 1.00 mm straight-cylindrical shank; typical fitment includes CNC machining centers, drill presses, and micro drill units configured for miniature-series solid carbide tooling.

Installation Notes

Micro drill bits of this diameter are installed by qualified machinists using a precision collet or drill chuck rated for the 1.00 mm shank size. Ensure the spindle and workpiece are fully secured before operation, as runout at this scale will break the bit. Feed rates and spindle speeds must be dialed in carefully for the workpiece material; excessive feed is the primary cause of micro drill failure. Inspect the cutting edge under magnification before each use to confirm the tip is intact.
