Accupro 12183598 Corner Radius End Mill 5/8 in 4 Flute Ticn

Product Description

The ACCUPRO 12183598 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous metals in machining center applications. It features a 5/8-inch mill diameter, a 0.06-inch corner radius, and a TiCN (Titanium Carbonitride) coating that improves wear resistance and extends tool life in abrasive cutting conditions. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. With 4 flutes and a 40-degree helix angle, it delivers efficient chip evacuation and a smooth surface finish. This is a single-end, centercutting tool, meaning it can plunge directly into the workpiece as well as perform peripheral and slot milling operations.

This end mill is suited for long-reach milling operations where a 2-inch length of cut is required. The corner radius geometry reduces stress concentration at the cutting edge, extending tool life and improving surface finish in applications such as profiling, contouring, and pocket milling. It is used in CNC machining centers in job shops, tool and die, aerospace component manufacturing, and general precision metalworking. Right-hand cutting and right-hand flute direction are standard for conventional CNC spindle setups.

Key Features

• TiCN coating increases surface hardness and reduces friction for extended tool life in abrasive materials
• 0.06-inch corner radius reduces cutting edge chipping and improves workpiece surface finish
• 40-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Micrograin solid carbide substrate supports high-speed machining with minimal deflection
• Centercutting design allows direct plunge entry into the workpiece
• Long-series length at 6 inches overall accommodates deep-reach milling setups

Compatibility

Designed as a direct-fit replacement or new-installation tool for CNC machining centers and manual knee mills accepting a 5/8-inch shank diameter collet or end mill holder. Compatible with standard right-hand spindle setups.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and the control is in E-stop or tool-change mode before inserting or removing the tool. Use a properly sized collet or hydraulic tool holder rated for the 5/8-inch shank diameter and torque the retention mechanism per the toolholder manufacturer specifications. Inspect the tool shank and holder bore for contamination or damage before each use, as runout directly affects corner radius accuracy and tool life.
