Iscar 3104439 Multimaster Replaceable Tip Milling Shank

Product Description

The ISCAR 3104439 is a replaceable tip milling shank from the Multimaster series, designed for modular milling tooling systems used in precision machining operations. This shank features a 90-degree stepped configuration with a straight shank shape, manufactured from solid carbide for rigidity and wear resistance. It carries a T08 neck thread for secure tip connection and supports coolant-through delivery to maintain cutting temperatures and improve chip evacuation. The overall length is 5.118 inches with an effective cutting length of 3.150 inches and a neck diameter of 0.453 inches. It is installed by machinists and tooling specialists working with CNC milling centers and machining cells.

This shank is suited for milling applications in both production and job-shop environments where modular tooling flexibility is required. The Multimaster platform allows tip interchange without removing the shank from the spindle, reducing changeover time. Compatible tip styles listed for this shank include BCM-MM, HCE-MM, HCM-MM, HP E90AN-MM-07, MM EB, MM EC-4, MM GRIT-K/P-45A, MM HBR, and MM HCR. The 12.00 mm shank diameter and 90-degree step geometry are suited for close-tolerance setups where projection and reach are critical parameters.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Ensure the spindle and toolholder are fully powered down and the machine is in a locked-out state before tip or shank changeout. Use proper torque tooling as specified by the machine tool manufacturer for the interface type. Confirm coolant-through passages are clear and unobstructed before returning to service.
