Iscar 3103222 Replaceable Tip Milling Shank 3/8 in

Product Description

The ISCAR 3103222 is a replaceable tip milling shank from the Multimaster series, designed for use with indexable milling systems that accept interchangeable cutting heads. This shank measures 3.25 inches in overall length with a 0.375-inch neck diameter and a T06 neck thread. The shank diameter is 3/8 inch with a straight, 90-degree shank shape and a Weldon flat for secure tool holding. Constructed from steel, this component provides the rigid interface between the machine spindle and the Multimaster cutting head. Installation is performed by machinists and toolroom technicians in CNC machining centers and milling operations.

This shank is suited for milling applications in both job shop and production machining environments. The Multimaster system is commonly used in vertical and horizontal machining centers where quick head changes reduce downtime. The 90-degree shank geometry and Weldon flat make it compatible with standard side-lock toolholders. The T06 neck thread interfaces directly with Multimaster-series replaceable cutting heads. The toolholder style is MM S-A-L3, and the manufacturers catalog number is MM TS-A-L3.25-C.375-T06.

Installation Notes

Installation should be performed by qualified machinists or toolroom personnel with the machine powered down and the spindle fully stopped before any tooling changes. Torque the shank into the toolholder per the machine tool manufacturer's specifications using appropriate wrenches. Confirm the Weldon flat is properly aligned with the side-lock set screw before securing. Inspect the T06 thread interface for contamination or damage before attaching a Multimaster cutting head.
