Accupro A-6100059R Micro Drill Bit 0.59 Mm Solid Carbide

Product Description

The ACCUPRO A-6100059R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. It measures 0.59 mm (0.0232 inches) in diameter with a 25 mm overall length and a 1.00 mm straight-cylindrical shank. The 120-degree point angle and spiral flute geometry support accurate hole entry and efficient chip evacuation at small diameters. The bright, uncoated finish is well suited for materials where coating buildup or adhesion would be a concern. This bit belongs to the Miniature series and is intended for machinists and precision tooling technicians working in electronics, instrumentation, and fine mechanical assembly.

This micro drill bit is used in applications requiring sub-millimeter hole diameters with consistent repeatability. Typical use cases include drilling through circuit boards, watch components, optical housings, and other precision-machined parts. The right-hand cutting direction and regular spiral flute type make it compatible with standard CNC machining centers, drill presses, and high-speed hand tools configured for small-diameter tooling. It is sold individually with a minimum order quantity of 10 units.

Key Features

• 0.59 mm (0.0232 inches) drill diameter for sub-millimeter precision work
• Solid carbide construction provides hardness and wear resistance at micro diameters
• 120-degree standard point angle for accurate hole entry and reduced walking
• Spiral flute with regular spiral type promotes chip clearing in deep micro holes
• Bright, uncoated finish maintains dimensional accuracy without coating thickness variation
• 1.00 mm straight-cylindrical shank fits standard micro toolholders and collets

Compatibility

Designed as an OEM-style replacement or direct-use micro drill bit for precision machining applications requiring a 0.59 mm diameter, 1.00 mm shank, straight-cylindrical tool in standard CNC or benchtop drilling setups.

Installation Notes

Installation and use should be performed by qualified machinists familiar with small-diameter tooling protocols. Ensure the spindle and collet are clean and properly torqued before seating the shank to avoid runout at micro diameters. At sub-millimeter sizes, feed rate and spindle speed must be dialed in carefully to prevent bit breakage — consult tooling manufacturer guidelines for speeds and feeds. Coolant-through is not supported on this bit; air blast or minimal lubrication is recommended where applicable.
