Iscar 5621319 End Milling Tip 0.375 in 4 Flute IC908 Carbide

Product Description

The ISCAR 5621319 is a carbide end replaceable milling tip in the MM EC-4 (Multimaster) series, designed for use with compatible Multimaster modular milling toolholders. This tip features a 0.375-inch cutting width, four flutes with a 45-degree helix angle, and a 90-degree lead angle. The substrate is sub-micrograin carbide in ISCAR grade IC908, finished with a TiAlN coating applied via PVD process. It is installed and replaced by machinists and CNC setup technicians in shop environments running steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

The 5621319 fits the Multimaster modular end milling platform and is suited for both roughing and finishing operations across a broad range of workpiece materials. The right-hand cut orientation, no-chipbreaker design, and 45-degree helix make it a general-purpose end milling solution. The functional length is 0.512 inches, with a maximum depth of cut of 0.275 inches and no coolant-through capability. This tip is appropriate for use in job shops, production facilities, and tool rooms where quick tip changeovers are required without removing the full assembly from the spindle.

Compatibility

Designed for use in ISCAR Multimaster modular milling systems accepting the MM EC-4 series end replaceable tips with a 0.375B27R000 insert size designation. Compatible workpiece materials include steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.

Installation Notes

Installation is performed by a machinist or CNC technician. The machine spindle must be fully stopped and the tool de-energized before tip removal or installation. Follow the toolholder manufacturer's torque and seating procedure for Multimaster-style tip connections. Verify tip seating and runout before initiating a cut.
