Accupro 12181225 Square End Mill 0.0394 in 2 Flute Carbide

Product Description

The ACCUPRO 12181225 is a solid carbide square end mill designed for precision milling in metalworking and machining applications. With a 0.0394 inch (1.00 mm) mill diameter and a 0.1575 inch (4.00 mm) length of cut, this tool handles tight-tolerance slotting, profiling, and contouring in small-scale work. The 2-flute geometry with a 30-degree helix angle and TiCN coating supports efficient chip evacuation and improved tool life in ferrous and non-ferrous materials. Micrograin carbide construction provides the edge retention and rigidity needed for fine detail cuts at high feed rates. Installed by machinists and CNC operators in job shop and production environments.

This end mill is suited for precision machining operations where small diameters and tight feature tolerances are required. Typical applications include micro-slotting, engraving, and detail profiling in die and mold work, medical component machining, and electronics hardware. The centercutting design allows plunge entry directly into the workpiece. Right-hand cut and right-hand flute configuration is standard for conventional CNC spindle setups. The 3.00 mm shank diameter fits compatible collets and tool holders designed for that shank size.

Key Features

• 0.0394 inch (1.00 mm) mill diameter for fine detail and micro-feature work
• TiCN coating for improved wear resistance and reduced friction
• Micrograin solid carbide construction for edge retention and rigidity
• 30-degree helix spiral flute promotes smooth chip flow
• Centercutting design enables direct plunge cuts
• Right-hand cut, right-hand flute for standard CNC spindle compatibility

Compatibility

Designed for use in CNC machining centers and manual milling machines equipped with a collet or tool holder accepting a 3.00 mm shank diameter.

Installation Notes

Installation and tool changes should be performed with the machine spindle fully powered down and locked out per OSHA lockout/tagout procedures. Use a properly sized collet or precision tool holder matched to the 3.00 mm shank diameter to ensure runout within acceptable limits. Verify shank insertion depth meets the tool holder manufacturer minimum engagement specification. Avoid excessive overhang beyond the specified overall length, as this increases deflection risk at this diameter.
