Accupro 12181298 Corner Radius End Mill 3/16 in 2 Flute Ticn

Product Description

The ACCUPRO 12181298 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 3/16 inch diameter, a 0.01 inch corner radius, and a TiCN (Titanium Carbonitride) coating that improves wear resistance and tool life compared to uncoated carbide. The 40-degree helix angle promotes smooth chip evacuation and reduces cutting forces. With two flutes and a centercutting design, this end mill handles both plunge and peripheral cutting. Machinists and CNC operators use it for finishing passes, contour work, and applications where a controlled corner break or radius is required on the finished part.

This end mill is suited for use in CNC machining centers and manual milling machines in job shop, toolroom, and production environments. The micrograin carbide substrate supports higher speeds and feeds in hardened steels, stainless, aluminum, and titanium. The single-end configuration and 5/8 inch length of cut make it well matched to shallow-to-medium depth slotting, profiling, and pocket milling where a small corner radius is specified on the workpiece geometry.

Key Features

• TiCN coating provides elevated hardness and lubricity for extended tool life in ferrous materials
• Micrograin solid carbide substrate supports aggressive feeds and speeds
• 0.01 inch corner radius reduces stress concentrations and chipping at the cutting edge
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Centercutting design allows direct plunge entry into the workpiece
• Right-hand cut and right-hand flute spiral for standard CNC spindle operation

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide corner radius end mill for standard 3/16 inch collet or end mill holder tooling systems used in CNC and manual milling applications.

Installation Notes

Installation and tool changes must be performed with the spindle fully stopped and the machine in a safe, locked-out state per applicable shop safety protocols. Seat the 3/16 inch shank fully into a clean, properly sized collet or end mill holder and torque to the tool holder manufacturer's specification. Inspect the cutting edges and corner radius under magnification before use; do not run a chipped or damaged tool. Tool runout should be checked with a dial indicator after installation to confirm concentricity within acceptable limits for the intended application.
