Iscar 5621402 Milling Tip 0.312 in 6 Flute Carbide IC908

Product Description

The ISCAR 5621402 is a corner radius end replaceable milling tip from the Multimaster MM EC-6 series. Made from sub-micrograin carbide with an IC908 grade and PVD-applied TiAlN coating, it is engineered for high-performance milling in demanding materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. The tip features a 0.312 inch cutting diameter, six flutes, a 30-degree helix angle, and a 0.015 inch corner radius. It is designed for right-hand cutting with a 90-degree lead angle and no chipbreaker. Licensed HVAC, machining, and metalworking professionals install this tip type in production and job shop environments.

This milling tip is used in Multimaster modular end mill systems where the cutting head is replaced independently of the shank, reducing tooling cost and changeover time. With a maximum depth of cut of 0.2 inches and a functional length of 0.394 inches, it suits finishing and semi-finishing passes on tight-tolerance components. The IC908 grade and TiAlN coating make it well-suited for interrupted cuts and high-heat applications common in aerospace, die-mold, and general metalworking. The tip ships individually with a minimum order quantity of 2.

Key Features

• Sub-micrograin carbide construction with IC908 grade for wear resistance in hard and abrasive materials
• PVD TiAlN coating for thermal stability and extended tool life in high-temperature cuts
• Six-flute design with 30-degree helix angle for smooth chip evacuation and surface finish
• 0.015 inch corner radius reduces stress concentration and improves edge durability
• Modular Multimaster MM EC-6 interface allows rapid head replacement without removing the shank from the machine
• Compatible with steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials per ISO material codes P, M, K, N, S, and H

Compatibility

Designed for use with ISCAR Multimaster modular milling systems accepting the MM EC-6 series replaceable tip interface. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metal, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by machining professionals following the tool manufacturer torque and engagement specifications for the Multimaster interface. Ensure the mating shank bore is clean and free of chips before seating the tip. Confirm spindle is fully stopped and machine is in an e-stop or lockout state before any tip change. Do not exceed the rated maximum depth of cut of 0.2 inches or the rated cutting diameter load for the IC908 grade.
