Iscar 5622121 Corner Radius Milling Tip IC908 Carbide

Product Description

The ISCAR 5622121 is a corner radius end replaceable milling tip from the Multimaster MM EC-3 series, designed for high-performance indexable milling operations. Built from sub-micrograin carbide in the IC908 grade with a PVD-applied TiAlN coating, this tip delivers reliable tool life across demanding cutting applications. It features a 0.500 inch cutting width, a 0.374 inch maximum depth of cut, and a 45-degree helix angle that promotes smooth chip evacuation. The three-flute configuration balances material removal rate with chip clearance. Licensed HVAC and trade professionals who operate CNC machining centers or manual mills will find this tip well-suited to production and maintenance shop environments.

This milling tip is engineered for use across a broad range of workpiece materials, including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its 90-degree lead angle and corner radius geometry make it suitable for shoulder milling and peripheral profiling operations in both roughing and semi-finishing passes. The right-hand cutting orientation and Multimaster-compatible interface support quick tip changes without removing the holder from the machine, reducing changeover time in production settings.

Key Features

• IC908 sub-micrograin carbide grade with PVD TiAlN coating for extended wear resistance
• 3-flute corner radius geometry with 0.031 inch corner radius for reduced edge chipping
• 0.500 inch cutting width and 0.374 inch maximum depth of cut
• 45-degree helix angle promotes efficient chip flow and reduced cutting forces
• MM EC-3 Multimaster interface for tool-free tip replacement at the spindle
• Right-hand cut, no chipbreaker, no coolant-through — suited for external coolant delivery

Compatibility

Designed for use with ISCAR Multimaster MM EC-3 series compatible holders. Refer to the ISCAR Multimaster catalog to confirm holder compatibility before ordering.

Installation Notes

This tip is installed by a machinist or tooling technician into a compatible Multimaster holder. Power down and lock out the machine spindle before changing milling tips. Use the appropriate ISCAR torque key for the Multimaster interface to seat the tip securely — do not use substitute tools. Confirm runout with a dial indicator after installation before beginning a cut.
