Accupro 12183485 Corner Radius End Mill 1/4 in 4 Flute

Product Description

The ACCUPRO 12183485 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous materials. It features a 1/4 inch cutting diameter, a 1 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The TiCN coating adds surface hardness and lubricity, improving performance in abrasive materials. With four right-hand spiral flutes and a 40-degree helix angle, this single-end, centercutting tool is suited for slotting, profiling, and plunge cuts in CNC machining centers and manual mills.

This end mill is intended for use in machine shops, tool rooms, and manufacturing environments where tight tolerances and consistent surface finishes are required. The long-length configuration and 4 inch overall length provide additional reach for deep-pocket and cavity work. The micrograin carbide substrate supports high cutting speeds and feeds while maintaining edge integrity. It is installed by machinists and CNC programmers in environments ranging from job shops to production floor operations.

Key Features

• 1/4 inch cutting diameter with a 0.06 inch corner radius for reduced edge chipping and improved part finish
• TiCN coating for enhanced hardness and wear resistance in abrasive materials
• Four right-hand spiral flutes at a 40-degree helix angle for efficient chip evacuation
• Centercutting design allows direct plunge entry into workpiece material
• Micrograin solid carbide substrate for dimensional stability and long tool life
• Single-end configuration with 4 inch overall length for extended reach in deep-cavity applications

Compatibility

Designed as an OEM-style replacement or direct-fit option for standard 1/4 inch shank collets and tool holders used in CNC machining centers and manual milling machines accepting ER or straight-shank tooling.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Ensure the collet and tool holder bore are clean and free of chips before seating the shank. Confirm runout with a dial indicator after clamping to maintain tolerance integrity. Follow the machine tool manufacturer guidelines for appropriate clamping torque on the collet nut.
