Accupro 12182597 Corner Radius End Mill 1/2 in 4 Flute Ticn

Product Description

The ACCUPRO 12182597 is a solid carbide corner radius end mill designed for precision milling operations in metalworking and machining environments. It features a 1/2 inch cutting diameter, a 1 inch length of cut, and a 1/8 inch (0.1250 inch) corner radius that reduces stress concentrations at the cutting edge and extends tool life in demanding applications. The TiCN coating improves surface hardness and wear resistance, making this tool well suited for ferrous and non-ferrous materials. With 4 flutes and a right-hand spiral flute geometry, it delivers efficient chip evacuation and a smooth finish. This end mill is single-end and centercutting, allowing plunge entry.

This end mill is intended for use in CNC machining centers and manual mills where corner-radius profiles, pocketing, and contouring operations are required. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. It is appropriate for job shop production, tool and die work, and precision part manufacturing. Machinists working with steel, stainless, cast iron, aluminum, and similar materials will find the TiCN coating and tight diameter tolerances beneficial for maintaining dimensional accuracy over extended run times.

Key Features

• Solid micrograin carbide construction for rigidity and edge retention
• TiCN coating for improved wear resistance and surface hardness
• 1/8 inch corner radius (0.1250 inch) with a tolerance of plus or minus 0.00150 inch
• Centercutting design allows direct plunge entry into workpiece
• Right-hand cutting and right-hand flute spiral for standard CNC and manual mill setups
• 4-flute configuration balances chip clearance and finish quality

Compatibility

Designed as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 1/2 inch straight shank. No specific OEM model compatibility was stated in the product data.

Installation Notes

This end mill is installed by a machinist or CNC setup technician into a collet or end mill holder accepting a 1/2 inch shank. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the tool. Observe the shank diameter tolerance of -0.0001 to -0.0004 inch when selecting holder fitment. Follow shop safety practices and machine manufacturer guidelines for runout inspection before initiating a cut.
