Accupro 12180358 Corner Rounding End Mill 3/8 in Carbide

Product Description

The ACCUPRO 12180358 is a double-end corner rounding end mill designed to produce consistent radius profiles on workpiece edges in milling operations. Built from solid carbide with a TiCN (titanium carbonitride) coating, it delivers hardness and heat resistance suited for cutting ferrous and non-ferrous metals, alloys, and similar materials. The tool features a 0.156-inch corner radius, a 3/8-inch mill diameter, and a 0.063-inch tip diameter. Two right-hand flutes with a right-hand cutting direction provide efficient chip evacuation. Machinists and tool-and-die professionals install this end mill in standard CNC or manual milling setups where edge rounding and profile accuracy are required.

This end mill is appropriate for shop and production environments where repeatable corner radii are needed on metal components. The double-end configuration extends tool life by offering two usable cutting ends, reducing downtime during high-volume or repetitive edge-profiling work. The 3/8-inch shank fits standard collets and tool holders of the same bore size, making it straightforward to integrate into existing setups without additional adapters in most cases.

Key Features

• Solid carbide construction for rigidity and wear resistance in metal cutting applications
• TiCN coating improves surface hardness and reduces friction at the cutting edge
• Double-end design provides two cutting ends per tool, extending usable tool life
• 0.156-inch corner radius with 0.063-inch tip diameter for precise edge profiling
• Right-hand cut and right-hand flute direction for standard milling spindle compatibility
• 2-flute geometry supports efficient chip clearance during edge-rounding passes

Compatibility

Designed as an OEM-style replacement or direct-use corner rounding end mill for standard 3/8-inch collet and tool holder setups in CNC and manual milling machines.

Installation Notes

Installation should be performed by a qualified machinist following the machine tool manufacturer's tooling guidelines. Ensure the spindle is fully stopped and the machine is in a safe, powered-down state before changing tooling. Confirm the collet or tool holder bore matches the 3/8-inch shank diameter before seating the tool. Follow applicable shop safety procedures and manufacturer feed and speed recommendations for the workpiece material and coating type.
