Accupro 12183302 Corner Radius End Mill 3/8 Inches 4 Flute

Product Description

The ACCUPRO 12183302 is a solid carbide corner radius end mill designed for precision milling in ferrous and non-ferrous materials. It features a 3/8 inch diameter with a 0.09 inch corner radius and a 1-3/4 inch length of cut, giving machinists a controlled edge profile that reduces stress concentration at corners. The AlTiN coating improves heat resistance and extends tool life in high-speed applications. With 4 right-hand spiral flutes and a 40-degree helix angle, this end mill promotes efficient chip evacuation and smooth cutting action. It is classified as an extra-long length tool at 4 inches overall. Centercutting capability allows for plunge operations where required.

This end mill is suited for CNC machining centers and manual mills used in job shops, production machining, and toolroom environments. The single-end design and 3/8 inch shank make it compatible with standard collet chucks and end mill holders. The AlTiN coating makes it a strong choice for dry or semi-dry cutting in alloy steels, stainless steels, and hardened materials. The extra-long overall length allows access in deep-pocket and deep-cavity milling applications where standard-length tools cannot reach.

Key Features

• 3/8 inch mill diameter with 0.09 inch corner radius for controlled edge profiling
• AlTiN coating for elevated heat resistance and extended tool life
• 40-degree helix angle with right-hand spiral flutes for efficient chip evacuation
• Centercutting design permits plunge milling operations
• Micrograin solid carbide construction for rigidity and wear resistance
• Extra-long 4 inch overall length for deep-pocket applications

Compatibility

Designed as an OEM-style replacement or direct-use end mill for CNC machining centers and manual mills accepting a 3/8 inch shank diameter with standard collet or end mill holder tooling.

Installation Notes

Installation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is powered down before inserting or removing the tool from the holder. Verify holder runout is within acceptable limits before use, as excessive runout accelerates wear on solid carbide tooling. Follow the machine tool manufacturer and tooling supplier guidelines for speeds, feeds, and depth-of-cut parameters appropriate to the workpiece material.
