Iscar 3103844 Milling Shank 3/4 in Multimaster Solid Carbide

Product Description

The ISCAR 3103844 is a solid carbide replaceable tip milling shank designed for use in modular tooling systems requiring precise, repeatable cutting-head exchanges. Built to Multimaster Series standards, this shank features a straight, 90-degree shank profile with a 0.75-inch shank diameter and a T12 neck thread for secure tip engagement. The overall length measures 8.0 inches, with an effective length of 4.5 inches and a neck diameter of 0.72 inches. This type of toolholder is installed and serviced by machining professionals and tool-room technicians working in CNC milling applications.

This shank is suited for milling operations where quick head changes and consistent tool reach are required. The Multimaster modular platform allows cutting tips to be swapped at the machine without removing the shank from the spindle, reducing downtime in production environments. The 4.43-inch head length and 4.5-inch projection provide reach suitable for pocketing, slotting, and profile milling in both ferrous and non-ferrous materials. The toolholder style is designated MM S-A within the Multimaster system.

Key Features

• Solid carbide construction for rigidity and vibration damping at extended reach
• T12 neck thread for positive, repeatable tip-to-shank connection
• 0.75-inch straight shank diameter with 90-degree shank type for standard collet or chuck mounting
• 8.0-inch overall length with 4.5-inch effective length for deep-reach milling setups
• 0.72-inch neck diameter provides clearance in tight-pocket operations
• Compatible tip style designations include BCM-MM, HCE-MM, HCM-MM, and additional Multimaster head families

Compatibility

Designed for use with Multimaster series replaceable milling tips including the following tip style families as stated by the manufacturer: BCM-MM, HCE-MM, HCM-MM, HM90 E90A-MM-10, HP E90AN-MM-07, MM EB, MM EC-4, MM ERS, MM HBR, and MM HCD.

Installation Notes

Installation and tool assembly should be performed by qualified machining personnel familiar with modular tooling systems. Ensure the spindle and toolholder are clean and free of chips or coolant residue before threading on a replacement tip. Torque the tip according to the tip manufacturer's documented procedure for T12 thread connections. This shank does not include coolant-through capability, so external coolant delivery should be used when required by the cutting application.
