Iscar 3103515 Milling Shank 5/8 in Multimaster

Product Description

The ISCAR 3103515 is a solid carbide replaceable tip milling shank in the Multimaster series, designed for modular milling tool assemblies used in precision metal removal operations. It features a 90-degree stepped shank configuration with a 0.625-inch shank diameter and a T10 neck thread, enabling fast, repeatable tip changes without removing the holder from the spindle. The neck diameter measures 0.6 inches, projection is 1.25 inches, and overall length is 3.25 inches. Licensed machinists and CNC setup technicians working in production milling environments are the primary users of this toolholder style.

This shank is suited for use in machining centers performing face milling, shoulder milling, and contour milling operations where modular tooling systems reduce changeover time. The Multimaster platform allows interchangeable milling tips to be swapped at the machine, making this shank a core component in high-mix, low-volume CNC environments as well as high-volume production cells. The straight shank shape and 90-degree stepped geometry are common in vertical and horizontal machining centers with standard collet or side-lock retention systems.

Key Features

• Solid carbide construction for rigidity and vibration damping during interrupted cuts
• T10 neck thread for secure, repeatable tip engagement in the Multimaster modular system
• 90-degree stepped shank with 0.625-inch diameter for standard spindle retention
• 1.25-inch effective length and 1.18-inch head length provide consistent reach and clearance
• No coolant-through design simplifies setup in standard flood-coolant environments
• Compatible with multiple Multimaster tip styles for flexible tooling configurations

Compatibility

Compatible milling tip styles include BCM-MM, HCE-MM, HCM-MM, HM90 E90A-MM-10, HP E90AN-MM-07, MM EB, MM EC-4, MM HBR, MM HCD, and MM HCR within the ISCAR Multimaster system. Toolholder style is MM S-A.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or removing the milling tip from the shank. Use the appropriate ISCAR torque key for the T10 neck thread to ensure proper tip engagement — do not use improvised tools that may damage the thread interface. Follow the machine tool manufacturer guidelines for shank retention torque and runout verification after assembly.
