Accupro A-6100118R Micro Drill Bit Size 56 1.18 Mm Carbide

Product Description

The ACCUPRO A-6100118R is a solid carbide micro drill bit designed for precision small-diameter drilling in tight-tolerance applications. Built to wire gauge size 56 with a decimal inch equivalent of 0.0465 inches (1.18 mm), this bit delivers accurate, repeatable hole geometry in hard and abrasive materials. The 120-degree point angle provides a stable entry and reduces walking on initiation. A bright/uncoated finish means no added coating thickness to affect dimensional accuracy. Right-hand spiral flute geometry promotes clean chip evacuation in the miniature series drilling operations this bit is engineered for. Licensed trades and machining professionals rely on this class of tool for instrumentation, electronics, and fine mechanical assemblies.

This micro drill bit is suited for precision drilling operations in metalworking, electronics manufacturing, and light mechanical fabrication environments. The straight-cylindrical shank seats directly in standard collets and drill chucks sized to accommodate 1.50 mm shank diameters. At 30 mm overall length, it is sized for use in CNC machining centers, benchtop drill presses, and hand-held precision drilling fixtures. Its miniature series designation makes it appropriate for applications where standard jobber-length bits are too large or too long for the workpiece or fixturing constraints.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Wire gauge size 56 — 1.18 mm (0.0465 inches) drill diameter for precision micro-hole work
• 120-degree standard point angle for stable entry and accurate hole placement
• Bright/uncoated finish preserves true diameter with no coating build-up
• Right-hand spiral flute with regular spiral type for efficient chip evacuation
• Straight-cylindrical shank at 1.50 mm diameter for broad collet and chuck compatibility

Compatibility

Designed for use in any precision drilling setup that accepts a 1.50 mm straight-cylindrical shank, including CNC machining centers, benchtop drill presses, and precision hand-held drilling fixtures requiring a wire gauge size 56 micro drill bit.

Installation Notes

This bit is installed by a machinist or tooling technician — ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the straight-cylindrical shank fully and evenly in the collet or chuck before tightening to the appropriate holding force for micro-diameter tooling. Solid carbide micro bits are brittle; avoid side loading, interrupted cuts beyond the tool design, or excessive feed rates that can cause snapping. Follow the machine manufacturer and tooling guidelines for speed and feed parameters appropriate to the workpiece material and hole depth.
