Accupro 2500131 Square End Mill 3/16 in 5 Flute Ticn Carbide

Product Description

The ACCUPRO 2500131 is a 5-flute, solid carbide square end mill designed for high-performance milling in ferrous and non-ferrous materials. It features a TiCN (titanium carbonitride) coating that increases surface hardness and reduces friction, extending tool life in demanding cutting applications. The 45-degree helix angle promotes efficient chip evacuation and smoother cutting action, while the micrograin carbide substrate provides the edge retention needed for tight-tolerance work. With a 3/16 inch diameter and stub-length geometry, this end mill is suited for applications requiring rigidity and precision in confined cutting environments. Machinists and toolroom operators install this tool in CNC machining centers and manual mills.

This end mill is intended for use in machining operations where a small-diameter, short-flute tool is required for slotting, profiling, and finishing cuts. The stub length type reduces deflection in high-feed operations. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC milling setups. It is appropriate for shop environments handling steels, stainless, cast iron, and similar materials where a TiCN-coated carbide tool is the specified choice.

Key Features

• 5-flute design increases feed rate capacity compared to 4-flute tooling of the same diameter
• TiCN coating improves wear resistance and reduces built-up edge in ferrous materials
• 45-degree helix angle promotes smooth chip flow and reduces cutting forces
• Micrograin solid carbide substrate delivers consistent edge sharpness and dimensional accuracy
• Centercutting geometry allows plunge entry without a pre-drilled hole
• Stub length type minimizes deflection for tight-tolerance profiling and slotting

Compatibility

Designed as a standard shank solid carbide square end mill compatible with ER collet chucks, end mill holders, and shrink-fit toolholders accepting a 3/16 inch shank diameter.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank to the full recommended grip depth in the toolholder to minimize runout and prevent pullout under load. Verify tool projection and runout with a dial indicator before beginning a cut, particularly in high-speed or high-feed applications.
