Iscar 5604101 Concave Radius Milling Tip Carbide IC908

Product Description

The ISCAR 5604101 is a concave radius replaceable milling tip from the Multimaster MM HR series, engineered for corner rounding operations on CNC milling platforms. The tip is ground from sub-micrograin carbide and coated with TiAlN via a PVD process, delivering the edge toughness and heat resistance required for interrupted cuts and high-feed finishing passes. With a cutting diameter of 0.185 inches and a maximum depth of cut of 0.472 inches, the 5604101 suits moderate radial engagement applications where profile accuracy matters. The 2-flute geometry maintains chip clearance in materials that work-harden quickly. Installation requires a compatible Multimaster shank holder and is performed by machinists and toolroom technicians.

This tip is designed for right-hand cutting and carries a 90-degree lead angle with no chamfer, producing a clean corner radius of 0.156 inches. The MM HR style is applicable across a broad material range including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Typical use cases include radius milling on aerospace components, die and mold profiling, and general machining of ferrous and non-ferrous parts where a replaceable tip system reduces tooling changeover time versus solid-shank end mills.

Key Features

• Sub-micrograin carbide substrate with IC908 grade designation for toughness in interrupted cuts
• TiAlN PVD coating for thermal resistance across steel, stainless, and superalloy applications
• 0.156-inch corner radius for consistent concave profile generation
• 2-flute right-hand geometry with no chipbreaker, suited for finishing and light roughing
• 90-degree lead angle and 0-degree chamfer for perpendicular entry into the workpiece
• No coolant-through design; external coolant or mist lubrication applies

Compatibility

Designed for use with compatible ISCAR Multimaster MM HR series shank holders. Insert size designation is 4.0/156-4.7. Confirm holder bore size and clamping style against the MM HR4.0/156-4.7-2T08 full tip description before ordering. Rated for primary workpiece material codes P, M, K, N, S, and H per ANSI standards.

Installation Notes

Replaceable milling tips in the Multimaster system are installed by toolroom technicians or machinists using the torque specifications defined by the holder manufacturer for the applicable shank size. Ensure the machine spindle is fully de-energized and the axis drives are locked before tip exchange. Clean the holder bore and seating face before installing a new tip to prevent seating errors that affect runout. Confirm tip engagement and seating visually before resuming cutting operations.
