Iscar 3103198 Milling Shank Multimaster 2.3in Projection

Product Description

The ISCAR 3103198 is a replaceable tip milling shank in the Multimaster series, designed for modular milling tool assemblies used in machining operations. The shank accepts Multimaster interchangeable cutting heads via a T10 neck thread, allowing fast head swaps without removing the holder from the spindle. Built from steel, this shank features a 1 inch straight shank diameter with an 85-degree shank type and a neck diameter of 0.598 inches. The 2.3 inch projection and 6.7 inch overall length make it well-suited for applications requiring extended reach in deep-pocket or contoured workpiece milling.

This shank is intended for use in CNC machining centers and milling machines where the Multimaster modular tooling system is employed. The Toolholder Style designation MM S-B places it within ISCARs standard straight-body Multimaster shank family. It is appropriate for production milling environments in aerospace, die and mold, and general metalworking shops where tool changeover speed and precision repeatability are priorities. Licensed machinists and CNC setup technicians are the primary installers of this component.

Compatibility

Designed for use within the ISCAR Multimaster modular milling system. Compatible with Multimaster cutting heads using the T10 thread interface. Toolholder style designation is MM S-B-L6.70-C1.00-T10 per the manufacturer catalog.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician. Before changing or seating the shank, ensure the machine spindle is fully stopped and the control is placed in a safe state. Use the appropriate Multimaster assembly torque wrench when seating interchangeable heads onto the T10 thread interface to ensure proper clamping without thread damage. Verify shank runout after installation with a dial indicator before beginning a cut.
