Iscar 4536008 Shell Mill Holder DIN69871-50 Taper Shank

Product Description

The ISCAR 4536008 is a taper-shank shell mill holder designed for use in CNC machining centers that accept DIN69871-50 tooling interfaces. This holder accepts shell mills via a 1.5748 inch (40 mm) pilot diameter and features a 3.2283 inch (82 mm) nose diameter. The projection from the flange to the nose end measures 1.0630 inches (27 mm), keeping the assembly compact and minimizing overhang. Machining professionals and toolroom technicians use this holder for face milling and shoulder milling operations requiring a rigid, repeatable connection between the spindle and the cutting tool.

This shell mill holder is intended for horizontal and vertical machining centers equipped with a DIN69871-50 taper-shank spindle. It is suited for medium to heavy face milling work in production environments where consistent tool runout and flange seating are critical. The holder does not include through-coolant capability, making it appropriate for applications where coolant is delivered externally. Installation is performed by qualified machinists or toolroom technicians during tool assembly and presetting operations.

Key Features

Compatibility

Designed as an OEM-style shell mill holder for machining centers with a DIN69871-50 taper-shank spindle interface and shell mills requiring a 1.5748 inch pilot bore.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician. Verify the spindle taper is clean and free of chips or burrs before seating the holder. Use the appropriate retention knob and drawbar torque specifications defined by the machine tool manufacturer. Inspect the pilot fit and face contact before running at full spindle speed.
