Iscar 5621384 Carbide Milling Tip 4 Flute Mm EC-4

Product Description

The ISCAR 5621384 is a carbide end replaceable milling tip designed for use in the Multimaster MM EC-4 system. It features a 0.625 inch cutting width, a 0.47 inch maximum depth of cut, and a 0.81 inch functional length. The tip is manufactured from sub-micrograin carbide in grade IC908 and carries a TiAlN coating applied via PVD process. The 45-degree helix angle and 4-flute geometry are suited to productive metal removal across a broad range of workpiece materials. This tip is installed by machining professionals working on CNC milling equipment in job shop, production, and aerospace environments.

The 5621384 is configured for right-hand cutting with a 90-degree lead angle and zero corner radius, making it appropriate for square-shoulder milling applications. It is rated for use on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, N, S, and H. The MM EC-4 interchangeable tip platform allows the tip to be swapped at the machine without removing the holder from the spindle, reducing changeover time in production settings.

Key Features

• Sub-micrograin carbide substrate with IC908 grade designation for wear resistance in demanding cuts
• TiAlN PVD coating for thermal protection and extended tool life across multiple workpiece materials
• 4-flute, 45-degree helix geometry for balanced chip evacuation and surface finish
• 90-degree lead angle with zero corner radius for true square-shoulder milling
• Right-hand cut orientation; no coolant-through feature
• ANSI standard compliance; Multimaster MM EC-4 series interchangeable tip system

Compatibility

Designed for use with ISCAR Multimaster MM EC-4 series holders that accept the .625B47R000 insert size. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials (ISO groups P, M, K, N, S, and H).

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Before swapping tips, ensure the machine spindle is fully stopped and locked out per facility lockout/tagout procedures. Seat the tip fully into the Multimaster holder interface and torque the retention screw using the appropriate ISCAR Multimaster torque key — do not use substitutes or impact drivers. Verify runout and tip seating before resuming cutting operations.
