Iscar 3103503 Milling Shank 90 Degree Stepped Multimaster

Product Description

The ISCAR 3103503 is a solid carbide replaceable tip milling shank designed for use with the Multimaster modular tooling system. It features a 90-degree stepped shank profile with a straight shank shape, a shank diameter of 0.312 inches, and a T05 neck thread with a neck diameter of 0.3 inches. The overall length is 3.5 inches, with an effective projection of 1.5 inches and a head length of 1.45 inches. This shank is used by machinists and tooling specialists in CNC milling operations where a modular, quick-change tip interface is required for efficient tool management and reduced changeover time.

This milling shank is intended for use in Multimaster-compatible milling setups, typically on CNC machining centers performing slotting, profiling, and contouring operations. It is compatible with the MM EB, MM EC-4, MM HBR, MM HCR, and MM TS-N tip styles within the Multimaster platform. The toolholder style is MM S-A, making it appropriate for light to moderate material removal applications where a compact, solid carbide shank provides rigidity and vibration resistance. It does not include a Weldon flat and does not support coolant-through delivery.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician familiar with modular milling systems. Ensure the machine spindle is fully stopped and locked out before mounting or removing the shank. Verify that the selected milling tip style is rated for the intended cutting application before assembly. Follow the machine tool manufacturer guidelines and applicable shop safety procedures when torquing the tip interface connection.
