Iscar 3103842 Replaceable Tip Milling Shank 3/4 in

Product Description

The ISCAR 3103842 is a solid carbide replaceable tip milling shank in the Multimaster series, designed for modular milling tool assemblies used in metalworking and machining operations. The shank features a 90-degree stepped straight shank with a 3/4 inch shank diameter and a T12 neck thread for secure connection to compatible Multimaster milling tips. The neck diameter measures 0.72 inches, the overall length is 4.0 inches, and the effective cutting projection is 1.5 inches. This toolholder is installed and serviced by machinists and CNC tooling technicians in production and job shop environments.

The 3103842 is suited for milling applications in CNC machining centers where modular tooling systems are used to reduce setup time and tooling inventory. The toolholder style is MM S-A, and it is compatible with a range of Multimaster milling tip styles including 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. The 90-degree stepped shank configuration is well suited for spindle interfaces that require positive axial location.

Key Features

• Solid carbide construction for rigidity and vibration resistance in demanding milling applications
• T12 neck thread for repeatable tip indexing within the Multimaster modular system
• 90-degree stepped straight shank with 3/4 inch diameter for common spindle and collet interfaces
• 1.5 inch projection and 4.0 inch overall length suit a range of reach requirements
• No coolant-through design keeps the configuration simple for dry or flood-coolant setups
• No Weldon flat on the shank

Compatibility

Compatible Multimaster milling tip styles 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. Verify tip thread size T12 and MM S-A toolholder style match before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling specialists. Power down and lock out the spindle before changing or indexing any milling tip on this shank. Use the appropriate Multimaster torque key or wrench as specified in the ISCAR Multimaster assembly procedure — do not use improvised tools on the tip thread. Confirm runout and projection after assembly before initiating a cutting pass.
