Iscar 5621392 Corner Radius Milling Tip 0.625 in 4 Flute

Product Description

The ISCAR 5621392 is a corner radius end replaceable milling tip from the Multimaster MM EC-4 series, designed for use in modular milling systems where quick tip changes are required without removing the holder from the machine. Built from sub-micrograin carbide in manufacturer grade IC908 with a PVD-applied TiAlN coating, this tip delivers wear resistance and thermal stability across demanding cutting applications. It features a 0.625-inch cutting width, a 0.015-inch corner radius, a 0.47-inch maximum depth of cut, and a 30-degree helix angle. The overall functional length is 0.81 inches. With four flutes and a right-hand cut orientation, it is suited for high-productivity milling passes in production environments.

This milling tip is intended for use in the ISCAR Multimaster modular tooling system. It is well suited for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Typical applications include shoulder milling, slotting, and profiling operations on CNC machining centers in both job shop and production environments. The 90-degree lead angle makes it effective for square shoulder milling. No coolant-through capability is present, so external coolant delivery should be used when required by the workpiece material or cutting conditions.

Key Features

• Sub-micrograin carbide substrate in IC908 grade for extended tool life in difficult-to-machine materials
• PVD TiAlN coating for high-temperature wear resistance and reduced built-up edge
• 0.625-inch cutting width with 0.015-inch corner radius reduces stress concentrations at the cutting edge
• Four-flute design supports higher feed rates and improved surface finish
• 30-degree helix angle promotes smooth chip evacuation and reduced cutting forces
• Replaceable tip format allows fast changeover without disturbing holder setup

Compatibility

Designed for use with the ISCAR Multimaster MM EC-4 modular milling system. Insert size designation is .625A47R015. Conforms to ANSI standards.

Installation Notes

Installation is performed by a machinist or tooling technician following the holder manufacturer torque and engagement guidelines for the Multimaster interface. Ensure the machine spindle is fully stopped and the tool is secured before tip installation or removal. Inspect the holder bore and tip seating surfaces for chips or contamination before engaging the tip. Do not use damaged or worn holders, as improper seating will affect runout and tool life.
