Accupro 12180352 Corner Rounding End Mill 1/8 in Radius

Product Description

The ACCUPRO 12180352 is a double-end corner rounding end mill designed for machining precise radius profiles on workpiece edges. Built from solid carbide with a titanium carbonitride (TiCN) coating, it delivers hardness and wear resistance suited to production milling environments. The tool features a 1/8 inch corner radius, a 5/16 inch mill diameter, and a 5/16 inch shank diameter. With two right-hand flutes and a right-hand cutting direction, it is sized for precision contouring passes where consistent edge geometry and surface finish are required. Machinists and tool and die professionals install this tool in CNC vertical and horizontal machining centers.

This end mill is appropriate for shops running ferrous and non-ferrous metals where corner breaking or rounding operations are required on milled components. The double-end configuration provides two usable cutting ends per tool, extending service life before replacement. The TiCN finish improves performance in harder materials by reducing heat buildup and edge wear. It is commonly used in toolrooms, job shops, and production cells handling tight-tolerance parts that require a clean, consistent radius without secondary deburring.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• TiCN coating reduces friction and extends cutting edge life
• Double-end design provides two cutting ends per tool
• 1/8 inch corner radius for consistent edge profiling
• Right-hand cut and right-hand flute geometry for standard CNC spindle compatibility
• Tip diameter of 0.0630 inches for precise corner engagement

Compatibility

Designed as an OEM-style replacement or standard tooling selection for CNC machining centers and manual mills accepting a 5/16 inch shank diameter end mill holder or collet.

Installation Notes

Installation is performed by a qualified machinist or toolroom technician. The machine spindle must be fully stopped and the tool changer or collet system de-energized before mounting or removing the tool. Verify collet or tool holder bore size matches the 5/16 inch shank before tightening. Follow the machine manufacturer guidelines and applicable shop safety procedures for tool runout inspection before cutting.
