Accupro 12180337 Corner Rounding End Mill 1/4 in 2 Flute

Product Description

The ACCUPRO 12180337 is a double-end corner rounding end mill designed for machining precise radius profiles on workpiece edges. Built from solid carbide and coated with TiCN (Titanium Carbonitride), it delivers hardness and wear resistance well above high-speed steel tooling. The 0.085-inch corner radius and 0.25-inch mill diameter make it suited to fine detail work where edge geometry and surface finish matter. With two right-hand flutes and right-hand cutting direction, it is a standard configuration for conventional CNC and manual milling operations. The double-end design extends usable tool life. Machinists and tool-and-die professionals install this type of cutter on vertical mills and CNC machining centers.

This corner rounding end mill is used in precision machining environments including tool rooms, job shops, and production floor applications. It is appropriate for profiling edges on ferrous and non-ferrous metals where a controlled 0.085-inch radius is required. The TiCN coating makes it particularly effective on harder steels and stainless materials where heat and abrasion are concerns. The 0.25-inch shank diameter is compatible with standard collet systems and tool holders found on most milling platforms.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding materials
• TiCN coating provides enhanced hardness and heat resistance compared to uncoated carbide
• Double-end design doubles usable cutting ends per tool
• 0.085-inch corner radius for precise, repeatable edge profiling
• Right-hand cut and right-hand flute direction for standard milling setups
• 0.25-inch shank diameter fits common collet and tool holder systems

Compatibility

Designed for use with standard 1/4-inch collet systems and tool holders on CNC machining centers and manual vertical mills. Verify spindle RPM and feed rate recommendations for the specific workpiece material before use.

Installation Notes

Installation is performed by qualified machinists. Power down and lock out the machine spindle before inserting or removing any end mill. Seat the shank fully into the collet or tool holder and torque the retention mechanism per the tool holder manufacturer specification. Inspect the cutting edges and coating for chips or wear before each use, and never exceed the tool diameter or material rating when selecting depth-of-cut parameters.
