Accupro 12180301 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12180301 is a solid carbide corner rounding end mill designed to produce precise, consistent radius profiles on workpiece edges. With a 0.015 inch cutting radius and a 1/8 inch mill diameter, this tool is built for detailed edge-finishing work on ferrous and non-ferrous materials. The TiCN (titanium carbonitride) coating increases surface hardness and reduces friction, extending tool life in demanding cutting conditions. The double-end configuration provides two usable cutting ends, maximizing value per tool. With two right-hand flutes and right-hand cutting direction, it is suited for use in standard CNC machining centers and manual mills.

This end mill is used in precision machining applications where edge-break consistency and tight radius tolerances are required. Typical applications include mold and die work, aerospace components, medical device manufacturing, and general CNC part finishing. The 1/8 inch shank diameter fits standard collet systems on vertical machining centers and CNC routers. It is best suited for light-to-medium-duty profiling passes on hardened steels, tool steels, stainless, aluminum, and similar materials where a uniform corner radius finish is specified on engineering drawings.

Key Features

• 0.015 inch corner radius produces consistent edge profiles in a single pass
• Solid carbide construction provides rigidity and wear resistance over high-speed cutting cycles
• TiCN coating increases surface hardness and reduces built-up edge on ferrous materials
• Double-end design offers two cutting ends per tool, extending usable tool life
• Right-hand cut and right-hand flute geometry compatible with standard spindle rotation
• 0.095 inch tip diameter suits tight-clearance profiling and detail work

Compatibility

Designed for use with standard 1/8 inch collet or end mill holders on CNC machining centers, CNC routers, and manual vertical mills equipped for solid carbide tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before changing tooling. Seat the 1/8 inch shank fully into the collet and torque the collet nut to the tool holder manufacturer specification. Verify runout with a dial indicator before beginning a production run, as excessive runout will reduce tool life and compromise radius accuracy.
