Accupro A-6100152R Micro Drill Bit 1.52 Mm Solid Carbide

Product Description

The ACCUPRO A-6100152R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a diameter of 1.52 mm (0.0598 inches) and a 120-degree drill point angle, it produces clean, accurate entry points in hard and abrasive materials. The bright/uncoated finish maintains dimensional consistency at the cutting edge. At 38.00 mm overall length with a 12.00 mm flute length and a 2.00 mm straight-cylindrical shank, this bit fits standard miniature drill chucks and collets. It is part of the Miniature Series, intended for machinists, tool and die technicians, and precision fabricators working at small scales.

This drill bit is suited for precision machining operations where small hole diameters and tight tolerances are required. Typical applications include PCB drilling, instrument components, medical device parts, and small-scale metal fabrication. The right-hand cutting direction pairs with conventional CNC machining centers, drill presses, and high-speed spindles. Solid carbide construction makes it appropriate for hardened steels, stainless steel, cast iron, and non-ferrous alloys where high-speed steel tooling would wear prematurely.

Key Features

• 1.52 mm (0.0598 inches) diameter for micro and miniature drilling applications
• Solid carbide construction resists wear in hard and abrasive materials
• 120-degree drill point angle for standard entry geometry
• Spiral flute, right-hand cut for chip evacuation in conventional setups
• Bright/uncoated finish preserves tight dimensional tolerances at the cutting edge
• Straight-cylindrical shank compatible with standard collets and miniature chucks

Compatibility

Designed as a miniature-series replacement or standard tooling choice for CNC machining centers, drill presses, and high-speed spindles accepting a 2.00 mm straight-cylindrical shank.

Installation Notes

Installation and tool changes should be performed with the machine powered down and spindle fully stopped. Ensure the shank is fully seated and clamped in the collet or chuck before operation. Micro drill bits are susceptible to breakage under side-loading or excessive feed pressure — verify feed rate and RPM settings against material specifications before drilling. A licensed machinist or qualified tooling technician should handle setup on precision equipment.
