Accupro A-6100183R Micro Drill Bit 1.83 Mm Solid Carbide

Product Description

The ACCUPRO A-6100183R is a solid carbide micro drill bit designed for precision drilling in tight-tolerance applications. With a 1.83 mm diameter and a 120-degree point angle, it delivers accurate entry and clean hole geometry in small-diameter work. The bright, uncoated solid carbide construction provides rigidity and wear resistance suited to hard and abrasive materials. Overall length is 38 mm, flute length is 12 mm, and the straight-cylindrical shank measures 2.00 mm in diameter. This bit is used by machinists, toolmakers, and precision fabricators who require repeatable micro-hole performance in production or prototype environments.

This micro drill bit fits drilling operations where small hole diameters and tight positional tolerances are required. Typical applications include PCB fabrication, instrument components, small mold cavities, medical device parts, and precision metalwork. The right-hand cut spiral flute configuration supports efficient chip evacuation in these demanding scenarios. It is sold individually with a minimum order quantity of 10 units per order, making it suitable for shop stock replenishment or production tooling kits.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard or abrasive materials
• 1.83 mm cutting diameter with 0.0720 decimal inch equivalent for cross-reference convenience
• 120-degree standard point angle for accurate hole entry and reduced walking
• Spiral flute, right-hand cut for effective chip evacuation
• Straight-cylindrical 2.00 mm shank for compatibility with standard micro-drill chucks and collets
• Bright, uncoated finish — no coating buildup to alter critical micro dimensions

Compatibility

Designed as an OEM-style replacement or production tooling option for standard micro-drill applications requiring a 2.00 mm straight-cylindrical shank in the miniature drill bit series.

Installation Notes

Install and removal should be performed by a qualified machinist with the spindle fully stopped and locked. Secure the straight-cylindrical shank in a properly sized collet or drill chuck to minimize runout at micro diameters. Inspect the cutting edges under magnification before use, as carbide micro drills are brittle and sensitive to chipping from side loads or improper seating. Follow machine manufacturer feed and speed guidelines for solid carbide micro tooling in the applicable workpiece material.
