Accupro 12180317 Corner Rounding End Mill 1/8 in 2 Flute

Product Description

The ACCUPRO 12180317 is a solid carbide corner rounding end mill designed to produce consistent, smooth radius profiles on workpiece edges. With a 0.04 inch radius and a 1/8 inch mill diameter, this tool is built for precision edge-breaking and blending operations on ferrous and non-ferrous materials. The double-end configuration provides two usable cutting ends, extending tool life between changeovers. An AlTiN coating improves heat resistance and wear performance in high-speed or dry machining environments. Machinists and CNC operators install this tool in milling machines and machining centers where controlled corner geometry is required.

This end mill is suited for precision milling applications in job shops, tool rooms, and production machining environments. Its small diameter and fine radius make it well matched for detail work on tight geometries, die work, and finishing passes on hardened or abrasive materials. The right-hand cutting and right-hand flute direction are standard for conventional CNC milling setups. Its compact 1/8 inch shank diameter is compatible with standard collet and end mill holder systems commonly used in vertical and horizontal milling machines.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• AlTiN coating provides elevated heat resistance for high-speed and dry cutting
• Double-end design delivers two cutting ends per tool
• 0.04 inch corner radius for consistent, repeatable edge profiling
• Right-hand cut and right-hand flute direction for standard CNC milling setups
• 0.045 inch tip diameter accommodates tight-radius detail work

Compatibility

Designed as an OEM-style replacement or standard tooling option for milling machines and machining centers accepting 1/8 inch shank end mills via collet or end mill holder systems.

Installation Notes

This tool is installed by machinists or CNC operators in a collet or end mill holder rated for the 1/8 inch shank diameter. Confirm runout and holder concentricity before operation to protect the carbide cutting edges. Power down and lock out the spindle before changing or inspecting tooling. Avoid side-loading beyond the tool geometry rating, and do not use this end mill for plunge operations unless the application specifically supports it.
