Accupro A-6100116R Micro Drill Bit 1.16 Mm Solid Carbide

Product Description

The ACCUPRO A-6100116R is a solid carbide micro drill bit designed for precision drilling in miniature and tight-tolerance applications. With a drill diameter of 1.16 mm (0.0457 inches) and a 120-degree drill point angle, this bit delivers accurate entry geometry suited for small-hole work in metals, composites, and similar materials. The bright/uncoated finish maintains dimensional integrity without added coating thickness, which is critical at this scale. Overall length is 30.00 mm, with a straight-cylindrical shank diameter of 1.50 mm. This bit is sold individually and must be ordered in multiples of 10.

This drill bit is used in precision machining environments where small-diameter through-holes or blind holes are required. Common applications include printed circuit board drilling, instrument manufacturing, mold and die work, and medical device component machining. The spiral flute geometry and right-hand cutting direction support chip evacuation in short-run and production drilling operations. It is appropriate for use in CNC machining centers, drill presses, and precision hand-held spindles configured for small-shank tooling.

Key Features

• 1.16 mm (0.0457 inch) drill diameter for tight-tolerance micro drilling
• Solid carbide construction for rigidity and wear resistance at small diameters
• 120-degree standard point angle for controlled entry geometry
• Bright/uncoated finish preserves true cutting-edge dimensions
• Straight-cylindrical shank at 1.50 mm for compatibility with standard collet chucks
• Spiral flute, right-hand cut for consistent chip removal

Compatibility

Designed as an OEM-style replacement or standard tooling selection for precision drilling setups requiring a 1.50 mm straight-cylindrical shank and a 1.16 mm cutting diameter in miniature-series applications.

Installation Notes

Installation and use should be performed by machinists or tooling technicians familiar with micro-diameter carbide drill bits. Ensure the spindle and collet are clean and properly torqued before seating the shank, as runout at this diameter accelerates bit breakage. Power down and de-energize the machine before changing tooling. Carbide bits at this scale are brittle and should not be used in setups with excessive vibration or misalignment.
