Promax 106-02414 Corner Radius End Mill 3/8 in 3 Flute

Product Description

The PROMAX 106-02414 is a single-end corner radius end mill designed for precision milling operations in metal fabrication and machining environments. Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), it handles high-temperature cutting applications where tool life and edge retention are critical. The 0.02-inch corner radius reduces stress concentration at the cutting edge and produces a controlled blend radius on workpiece profiles. With a 3/8-inch diameter, 7/8-inch length of cut, and a 35-degree helix, it is suited for right-hand cutting in a wide range of ferrous and non-ferrous materials. Machinists and tool-and-die professionals are the primary installers and users of this tool.

This end mill is used in CNC machining centers and manual mills for slotting, profiling, and peripheral milling where a corner radius is required on the finished part. The regular-length geometry and 3/8-inch shank diameter make it compatible with standard ER and end mill holders. It is a strong fit for mold and die work, aerospace component machining, and general precision part production where tight diameter tolerances and consistent edge geometry are required.

Key Features

• Micrograin solid carbide construction for hardness and wear resistance in demanding cuts
• AlTiN coating extends tool life in high-heat, high-speed cutting conditions
• 0.02-inch corner radius reduces chipping and produces a controlled radius blend on part profiles
• 35-degree helix angle promotes efficient chip evacuation and smooth cutting action
• Right-hand flute direction and right-hand cutting orientation for standard CNC mill setups
• Single-end design with 3 flutes balances chip clearance and cutting surface contact

Compatibility

Designed as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3/8-inch shank end mill holder.

Installation Notes

Installation is performed by machinists using a compatible end mill holder or collet chuck torqued to the tool holder manufacturer's specifications. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool. Verify shank seating depth and runout with a dial indicator before beginning a cut. Follow shop-standard speeds and feeds for carbide end mills based on workpiece material and depth of cut.
