Iscar 3103153 Replaceable Tip Milling Shank Multimaster

Product Description

The ISCAR 3103153 is a replaceable tip milling shank designed for use with the Multimaster modular tooling system. It features a 90-degree straight shank configuration with a T05 neck thread, allowing quick exchange of milling heads without removing the shank from the machine spindle. The shank diameter and neck diameter are both 0.312 inches, and the overall length measures 2.75 inches. Constructed from steel, this shank is built to handle the rigidity demands of milling operations in CNC machining centers. A Weldon flat is included for secure clamping in the toolholder. Licensed machinists and tooling setup technicians are the primary users of this component.

This shank is intended for milling applications in shops running ISCAR Multimaster modular tooling. The Multimaster system is commonly found in production machining environments handling a range of materials where quick tool changes and consistent runout are priorities. The Toolholder Style designation is MM S-A-L2, and the manufacturer catalog number for this shank is MM TS-A-L2.75-C.312-T05. It is suited for use in vertical and horizontal machining centers where a 0.312-inch straight shank is compatible with the spindle or toolholder bore.

Installation Notes

Installation should be performed by a qualified machinist or tooling specialist familiar with modular milling systems. Ensure the machine spindle is fully stopped and the tool is secured before mounting or dismounting any shank or cutting head. Use the Weldon flat engagement surface with the appropriate set screw torque per the machine toolholder manufacturer specifications. Verify thread engagement on the replaceable tip is complete and snug before initiating any cutting cycle.
