Iscar 3102901 Replaceable Tip Milling Shank Multimaster

Product Description

The ISCAR 3102901 is a solid carbide replaceable tip milling shank from the Multimaster series, designed for modular milling tool assemblies used in precision machining operations. The shank features a 90-degree stepped configuration with a 1/2-inch shank diameter and a T08 neck thread, allowing fast, repeatable head changes without removing the holder from the machine. With a total overall length of 5.5 inches and a projection of 2.5 inches, this shank is suited for applications requiring extended reach and consistent tool centerline positioning. Coolant-through capability supports chip evacuation and heat control during high-feed milling. CNC machinists and toolroom professionals install this component as part of a modular tooling setup on machining centers.

The 3102901 is intended for use in milling applications on CNC machining centers where the Multimaster modular tooling system is employed. The 90-degree stepped shank interfaces with standard toolholder styles compatible with the MM S-A toolholder style designation. Its straight shank shape and 1/2-inch diameter make it compatible with a wide range of collet chucks and end mill holders used in vertical and horizontal milling setups. The T08 neck thread provides a secure, precise connection to Multimaster-series replaceable milling heads.

Key Features

• Solid carbide construction for rigidity and vibration resistance during milling
• T08 neck thread for secure, repeatable head changes in Multimaster modular systems
• Coolant-through design supports chip removal and thermal management at the cutting zone
• 90-degree stepped shank with 1/2-inch diameter suits standard collet and end mill holder interfaces
• 5.5-inch overall length with 2.5-inch projection for extended-reach milling operations
• Neck diameter of 0.48 inches and head length of 2.45 inches provide clearance in tight-profile cuts

Compatibility

Designed for use with the Multimaster modular milling system using the MM S-A toolholder style. Replaceable milling heads with T08 thread compatibility are required. Refer to the manufacturer catalog number MM S-A-L5.50-C.50-T08-M-C for cross-reference when sourcing compatible heads or holders.

Installation Notes

Installation should be performed by a qualified CNC machinist or toolroom technician familiar with modular tooling systems. Ensure the machine spindle is fully stopped and the tool is secured in the toolchanger or a safe fixture before assembling or disassembling the replaceable head. Use the manufacturer-specified tightening procedure for T08 threaded connections to avoid cross-threading or over-torquing the carbide interface. Verify coolant-through passages are clear and aligned before returning the assembly to service.
