Promax 100-03614 Corner Radius End Mill 9/16 in 4 Flute Carbide

Product Description

The PROMAX 100-03614 is a solid carbide corner radius end mill designed for precision milling operations in ferrous and non-ferrous metals. It features a 9/16-inch cutting diameter with a 1-1/4-inch length of cut and a corner radius range of 0.055 to 0.065 inches, allowing controlled edge blending and reduced stress concentration at part corners. The four-flute geometry and 30-degree helix angle promote efficient chip evacuation and smooth surface finishes. An AlTiN coating provides thermal resistance and extended tool life in high-speed applications. The 9/16-inch shank diameter and 3-1/2-inch overall length suit standard collet and end mill holder setups on CNC machining centers and manual mills.

This end mill is suited for finish and semi-finish milling passes where a radiused corner profile is required on mold cavities, die components, aerospace parts, and general precision machined components. The centercutting design allows plunge entry, adding versatility for ramp and helical interpolation toolpaths. Right-hand cutting and right-hand flute direction align with standard spindle rotation on conventional vertical and horizontal machining centers. It belongs to the PROMAX Series 100 and carries a coarse pitch classification.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding cuts
• AlTiN coating for elevated temperature resistance and extended tool life
• Corner radius range of 0.055 to 0.065 inches reduces stress risers and improves part edge quality
• Four flutes with 30-degree helix for efficient chip flow and smooth finish
• Centercutting capability supports plunge, ramp, and helical entry toolpaths
• Matched 9/16-inch shank and cutting diameter for direct fitment in standard toolholders

Compatibility

Designed for use in standard 9/16-inch collet chucks, end mill holders, and shrink-fit toolholders on CNC machining centers and manual knee mills requiring a corner radius end mill with a 9/16-inch shank diameter.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the spindle fully stopped and machine power locked out per shop safety procedures. Ensure the shank is fully seated and properly torqued in the toolholder before running. Verify spindle RPM and feed rate parameters against the tool manufacturer recommendations for the workpiece material and coating type before beginning a cut. Do not exceed the rated length of cut to avoid deflection or tool breakage.
