Iscar 3105838 Multimaster Milling Shank ER32 Collet

Product Description

The ISCAR 3105838 is a replaceable tip milling shank from the Multimaster series, designed for use in milling operations requiring a secure collet-style interface. Built from solid carbide, this shank features an ER32 taper and a T08 neck thread, making it compatible with a wide range of Multimaster interchangeable milling heads. The overall length is 3.724 inches (94.60 mm), with a 1.970-inch (50.00 mm) effective cutting length and a neck diameter of 11.60 mm. Coolant-through capability supports chip evacuation and heat management during demanding milling operations. This shank is installed by CNC machinists and tooling specialists in machine shop environments.

The 3105838 is suited for milling applications in both production and job shop settings where quick tip changeability reduces downtime. The ER32 collet taper interfaces with standard ER32 collet chucks, and the conical shank shape ensures rigid seating. The toolholder style is MM S-ER, a standard configuration within the Multimaster platform. This shank accepts multiple Multimaster head styles, allowing a single shank body to serve a variety of milling profiles and materials without replacing the entire assembly.

Installation Notes

Installation is performed by a qualified CNC machinist or tooling technician. The machine spindle must be fully stopped and the tool changer disabled before mounting or removing the shank. Use a calibrated torque wrench appropriate for ER32 collet nuts when securing the shank in the chuck. Verify coolant-through passages are clear and properly aligned with the machine spindle coolant port before operation.
