Iscar 5623325 End Replaceable Milling Tip 4 Flute Carbide

Product Description

The ISCAR 5623325 is a carbide end replaceable milling tip in the Multimaster MM EC-4 series, designed for use with compatible Multimaster modular milling systems. It features a 0.187-inch cutting diameter, a maximum depth of cut of 0.270 inches, and a functional length of 0.591 inches. The tip is manufactured from sub-micrograin carbide in the IC908 grade and carries a TiAlN coating applied via PVD process. With a 4-flute configuration and a 45-degree helix angle, it is suited for high-productivity milling operations. This tip is installed and replaced by machinists and CNC toolroom technicians in production and job-shop environments.

The 5623325 is intended for milling steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. Its right-hand cut orientation and 90-degree lead angle make it applicable for square-shoulder milling and end milling operations. The tip mounts directly onto Multimaster MM EC-4 compatible holders, eliminating the need to replace the full tool body when the cutting end is worn. Typical applications include finishing and semi-finishing passes on a wide range of workpiece materials across both manual and CNC milling platforms.

Key Features

• Sub-micrograin carbide construction in IC908 grade for wear resistance across difficult materials
• TiAlN coating via PVD process for thermal stability and extended tool life
• 4 flutes with 45-degree helix angle for efficient chip evacuation
• 0.187-inch cutting diameter with 0.270-inch maximum depth of cut
• Right-hand cut, 90-degree lead angle suitable for square-shoulder milling
• Replaceable tip design reduces tooling cost by preserving the holder body

Compatibility

Designed for use with Multimaster MM EC-4 series compatible modular milling holders. Insert size designation is .187B27R000 per the MM EC-4 system. Conforms to ANSI standards.

Installation Notes

Installation is performed by machinists or CNC toolroom technicians. The milling spindle must be fully powered down and locked out before removing or seating the tip. Use the appropriate Multimaster torque wrench or assembly tool as specified by the holder manufacturer to seat the tip correctly — do not use standard hex keys or improvised tools. Verify tip seating and runout before resuming cutting operations.
