Iscar 5622942 Corner Radius End Mill 3/8 in 3 Flute Carbide

Product Description

The ISCAR 5622942 is a solid carbide corner radius end mill designed for high-performance material removal in non-ferrous metal applications. It features a 3/8-inch cutting diameter with a 0.06-inch corner radius, three flutes, and a variable helix geometry that reduces chatter and improves surface finish at the cut. The short flute length type and extended reach configuration make it well-suited for both roughing and finishing passes in a single tool. At 2.5 inches overall length with a 3/8-inch straight cylindrical shank, this end mill fits standard toolholders and runs right-hand cutting direction. The fine grain solid carbide substrate is left uncoated, making it optimally matched to non-ferrous materials where uncoated tooling outperforms coated alternatives.

This end mill is intended for use on CNC machining centers and manual mills where non-ferrous metals such as aluminum, copper, and brass are the primary workpiece material. The coarse pitch combined with the variable helix makes it effective for both slotting and profiling operations. The center-cutting capability allows plunge entry without a pre-drilled pilot hole. It is part of the ISCAR ECAI-H3-CF series and is suited for shops running production or job-shop work on non-ferrous components requiring tight tolerances. The h6 diameter tolerance on both the mill and shank diameters supports accurate tool runout and repeatable fitment in precision collets and hydraulic chucks.

Key Features

• Variable helix geometry reduces harmonic vibration and chatter during cutting
• Corner radius of 0.06 inches strengthens the cutting edge and improves tool life versus sharp-corner end mills
• Center-cutting design allows direct plunge entry into the workpiece
• Fine grain solid carbide construction provides rigidity and wear resistance in non-ferrous applications
• Extended reach configuration with 1.125-inch reach length suits deeper cavity and shoulder milling
• h6 tolerance on mill and shank diameters ensures accurate fitment in precision toolholding systems

Compatibility

Designed for use with standard toolholders accepting a 3/8-inch straight cylindrical shank. Primary workpiece material is non-ferrous metal. Part of the ISCAR ECAI-H3-CF series.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the toolholder and torque the retention mechanism to the toolholder manufacturer specification. Verify tool runout with a dial indicator before beginning the cut, particularly for finishing operations where surface quality is critical.
