Accupro A-6100147R Micro Drill Bit 1.47 Mm Solid Carbide

Product Description

The ACCUPRO A-6100147R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 1.47 mm diameter and a 120-degree point angle, this bit delivers accurate entry and controlled chip evacuation in hard and abrasive materials. The bright, uncoated finish is suited for applications where coating buildup tolerance is critical. At 30 mm overall length with an 11.20 mm flute length, it fits standard micro drilling setups. The straight-cylindrical shank at 1.50 mm diameter seats securely in collet-style toolholders. Machinists and toolroom technicians working in electronics, aerospace, or precision instrument fabrication are the primary users of this part.

This micro drill bit is engineered for drilling small-diameter holes in materials that demand dimensional accuracy. The spiral flute geometry promotes chip clearing during through-hole and blind-hole operations. The regular spiral type and right-hand cutting direction make it compatible with standard CNC machining centers, drill presses, and high-speed spindle setups. It is sold individually per package, with a minimum order quantity of 10 units, making it appropriate for shops that maintain consistent tooling inventories for repeat micro-drilling operations.

Key Features

• 1.47 mm cutting diameter, equivalent to 0.0579 inches decimal
• Solid carbide construction for rigidity and wear resistance in hard materials
• 120-degree standard point angle for accurate hole entry
• Spiral flute design promotes chip evacuation during drilling
• Bright, uncoated finish — no coating interference in precision bore applications
• Straight-cylindrical shank at 1.50 mm for secure collet or chuck retention

Compatibility

Designed as an OEM-style replacement and standard tooling option for micro drill applications requiring a 1.50 mm straight-cylindrical shank in collet holders, CNC machining centers, and benchtop drill presses configured for miniature-series tooling.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the shank fully within a compatible collet or drill chuck before operation, and verify runout with a dial indicator when tolerances are critical. Always power down and lock out the spindle before changing tooling. Observe manufacturer spindle speed recommendations for the workpiece material when using carbide micro drills, as excessive feed rate or lateral force can cause bit fracture at this diameter.
