Accupro 12183605 Corner Radius End Mill 5/8 in 4 Flute

Product Description

The ACCUPRO 12183605 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals, hardened steels, and high-temp alloys. It features a 5/8 inch cutting diameter, a 0.03 inch corner radius, and four right-hand spiral flutes with a 40-degree helix angle for efficient chip evacuation and reduced cutting forces. The AlTiN coating extends tool life at elevated temperatures, making this end mill well suited for dry and high-speed machining environments. Machinists and toolroom operators select this tool for applications demanding close tolerances and smooth surface finishes.

This end mill is built for use in vertical machining centers, CNC mills, and manual knee mills across job shops, production floors, and toolroom settings. The long-length designation, 6 inch overall length with a 2 inch length of cut, allows access to deeper features such as pockets, slots, and contoured profiles. The centercutting geometry enables plunge entry directly into the workpiece. The single-end configuration and 5/8 inch shank diameter are compatible with standard ER and end mill holders used in typical milling setups.

Key Features

• 5/8 inch cutting diameter with 0.03 inch corner radius for blended edge transitions and reduced stress concentrations
• AlTiN coating for high heat resistance and extended tool life in dry or semi-dry machining
• 40-degree helix angle promotes smooth cutting action and efficient chip removal
• Micrograin solid carbide substrate provides rigidity and wear resistance across demanding materials
• Centercutting design allows direct plunge milling without pre-drilling
• Right-hand cut, right-hand flute spiral in a long-length, single-end configuration

Compatibility

Designed for use in standard 5/8 inch end mill holders, ER collet chucks, and hydraulic or shrink-fit toolholders commonly found in CNC vertical machining centers and manual mills.

Installation Notes

Installation should be performed by a qualified machinist following shop safety procedures. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the holder to the recommended engagement depth and torque the retention screw or collet nut to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning the cut, as excessive runout will accelerate wear and compromise tolerance on corner radius features.
