Iscar 3103409 Multimaster Milling Shank 0.312 Inch

Product Description

The ISCAR 3103409 is a replaceable tip milling shank from the Multimaster series, designed for modular milling tool assemblies used in CNC machining operations. The shank features a 90-degree stepped configuration with a straight shank shape and a 0.312-inch shank diameter, making it compatible with standard Multimaster head connections. Constructed from steel, this shank delivers the rigidity required for consistent performance in milling applications. The T05 neck thread and 0.3-inch neck diameter allow precise coupling with Multimaster cutting heads. Coolant-through capability supports chip evacuation and thermal management during cutting.

This shank is suited for use in milling operations on machining centers where Multimaster-style modular tooling is employed. The 90-degree stepped shank style is commonly used in applications requiring a specific projection and clearance geometry. With an overall length of 2.5 inches and a projection of 0.6 inches, this shank fits standard tool assemblies in both production and job shop environments. It is installed and serviced by machinists and CNC tooling technicians.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians following shop tooling procedures. Power down and de-energize the spindle fully before removing or installing any tooling components. Use the appropriate torque wrench and Multimaster assembly tools as specified by the tooling system manufacturer. Inspect the neck thread and seating surfaces for damage or contamination before assembly to ensure accurate head-to-shank coupling.
