Accupro 12180316 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12180316 is a double-end corner rounding end mill designed for precision edge-breaking and radius milling on metal workpieces. Built from solid carbide and coated with TiCN (Titanium Carbonitride), it delivers extended tool life and improved wear resistance in demanding cutting applications. The mill features a 0.04-inch corner radius and a 0.125-inch (1/8 inch) diameter, making it well suited for tight-tolerance work where consistent, repeatable edge geometry is required. With 2 right-hand flutes and right-hand cutting direction, it is a standard choice for machinists working on CNC machining centers and manual mills alike.

This end mill is used in metalworking shops for rounding sharp corners and producing uniform radius profiles on ferrous and non-ferrous materials. The double-end configuration provides two usable cutting ends, extending overall tool value per unit. It is appropriate for light to moderate material removal passes where edge finishing and dimensional consistency are the priority. The 1/8-inch shank diameter fits standard collet systems commonly found on CNC mills, tool-and-die setups, and precision machining operations.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• TiCN coating reduces friction and extends tool life compared to uncoated carbide
• Double-end design provides two cutting ends per tool
• 0.04-inch corner radius for consistent, tight-tolerance edge rounding
• Right-hand cut and right-hand flute geometry for standard spindle operation
• 0.045-inch tip diameter suited for fine-detail corner profiling

Compatibility

Designed as a direct-fit replacement for 1/8-inch shank collet systems used in CNC machining centers and manual milling setups requiring a 0.04-inch corner radius end mill.

Installation Notes

Installation should be performed by a qualified machinist following standard tooling procedures. Ensure the spindle is fully stopped and locked out before inserting or removing the end mill from the collet. Verify collet size matches the 1/8-inch shank diameter and that the tool is seated and torqued to the collet manufacturer specification. Inspect the cutting edges for chips or wear before each use, particularly on the double-end tool where the second end may have been previously run.
