Accupro 12183445 Corner Radius End Mill 1 in 4 Flute Carbide

Product Description

The ACCUPRO 12183445 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. Built with a 1-inch diameter and a 0.06-inch corner radius, it reduces stress concentrations at the cutting edge and produces consistent radii on part features. The AlTiN coating extends tool life in high-temperature cutting environments by improving wear resistance and thermal stability. With 4 flutes and a right-hand spiral flute direction, this tool is suited for roughing and finishing passes in professional CNC machining applications. It is a centercutting design, allowing plunge entry.

This end mill is used in CNC machining centers for milling steel, stainless steel, hardened alloys, and similar materials where a corner radius profile is required on slots, pockets, or contoured surfaces. The long-length configuration, with a 2-inch length of cut and 6-inch overall length, provides reach in deeper cavity work. It is a single-end tool installed in standard 1-inch collet or end mill holders. Typical users include CNC machinists and toolroom operators in production and job shop environments.

Key Features

• Solid micrograin carbide construction for rigidity and wear resistance
• AlTiN coating for thermal protection and extended tool life in high-speed cutting
• 0.06-inch corner radius reduces edge chipping and stress on machined part corners
• 4-flute, right-hand spiral design supports efficient chip evacuation and smooth surface finish
• Centercutting geometry allows direct plunge milling without pre-drilled entry
• Long-length body with 2-inch length of cut accommodates deeper slot and pocket operations

Compatibility

Designed for use in CNC machining centers with standard 1-inch end mill holders or collet chucks accepting a 1-inch shank diameter. Suitable for corner radius profiling and slot milling in steel, hardened alloys, and similar ferrous materials.

Installation Notes

Installation is performed by a qualified CNC machinist or toolroom technician. Ensure the machine spindle is fully stopped and the tool holder is clean and free of debris before seating the shank. Torque the set screw or collet nut to the tool holder specification. Verify runout at the cutting diameter before beginning a production cut.
