Promax 119-02424 Corner Radius End Mill 3/8 Inch Altin

Product Description

The PROMAX 119-02424 is a solid carbide corner radius end mill designed for roughing and finishing operations in a single tool. It features a 3/8-inch cutting diameter, three flutes, and a 0.02-inch corner radius on a corner radius end geometry. The AlTiN coating provides heat and wear resistance for demanding cutting conditions. The 40-degree helix angle improves chip evacuation and surface finish. Machinists and tool-and-die professionals use this end mill in CNC machining centers for high-speed metal removal and semi-finish passes on ferrous and hard alloy workpieces.

This end mill suits applications in job shops, production machining, and aerospace or mold-and-die environments where corner radius geometry is required to reduce stress concentrations at pocket corners or on contoured surfaces. The single-end, right-hand cutting configuration fits standard CNC mill toolholders with a straight cylindrical shank. The micrograin carbide substrate supports rigidity at elevated speeds and feeds typical of finish machining operations.

Key Features

• 3/8-inch cutting diameter with 0.02-inch corner radius for reduced stress at part corners
• AlTiN coating for extended tool life in ferrous and hardened alloy materials
• 40-degree helix angle promotes efficient chip evacuation and smooth surface finish
• Micrograin solid carbide substrate for rigidity and wear resistance
• Center-cutting capable, allowing plunge entry into workpiece material
• Right-hand flute direction and right-hand cutting for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and milling machines accepting a 3/8-inch straight cylindrical shank toolholder.

Installation Notes

Installation should be performed by a qualified machinist familiar with CNC toolholder setup and runout requirements. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a precision collet or shrink-fit holder to maintain runout within the shank diameter tolerance of -0.0001 to -0.0004 inches. Verify tool projection and reach before beginning any cutting cycle.
