Accupro 12183152 Corner Radius End Mill 3/4 in 4 Flute Altin

Product Description

The ACCUPRO 12183152 is a solid carbide corner radius end mill designed for precision milling of ferrous and non-ferrous metals. It features a 0.750 inch mill diameter, a 2.25 inch length of cut, and a 0.125 inch corner radius that reduces stress concentration at the tool tip and extends part life in high-demand applications. The AlTiN coating provides high heat resistance and wear performance at elevated cutting speeds. With four right-hand spiral flutes and a 40-degree helix angle, this tool is suited for aggressive material removal while maintaining finish quality. Micrograin carbide construction supports tight tolerances and consistent performance across production runs.

This end mill is used in vertical and horizontal machining center applications where corner radius profiles are required on part features. The single-end, centercutting design allows plunge entry and full-slot milling. The long flute length relative to diameter makes it appropriate for deeper pocket milling and side-wall work. It is installed and operated by CNC machinists and toolroom operators in job shops, aerospace, automotive, and general manufacturing environments.

Key Features

• 0.750 inch mill diameter with micrograin solid carbide construction for rigidity and wear resistance
• 0.125 inch corner radius reduces tool stress and produces consistent radii on part edges
• AlTiN coating extends tool life at high cutting temperatures and speeds
• 4 right-hand spiral flutes with 40-degree helix angle for efficient chip evacuation
• Centercutting geometry allows direct plunge entry without a pre-drilled hole
• 3/4 inch shank diameter for secure holder engagement and reduced runout

Compatibility

Designed as an OEM-style solid carbide corner radius end mill for use in standard 3/4 inch collet chucks, end mill holders, and shrink-fit tooling systems on CNC machining centers.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom operator. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder to the recommended gauge length and torque set screws or collet nuts per the toolholder manufacturer specifications. Verify runout with a dial indicator before commencing a production cut, and confirm cutting parameters are appropriate for the workpiece material and coating type.
