Value Collection 219-4106 Shell Mill Holder 4MT Taper

Product Description

The VALUE COLLECTION 219-4106 is a 4MT taper shank shell mill holder designed for mounting shell mills on milling machines equipped with a Morse taper spindle. It features a 1-1/4 inch pilot diameter and accommodates shell mill cutting diameters ranging from 3 inches to 3-1/2 inches. Weighing 2.3 pounds, this holder provides a rigid mechanical connection between the machine spindle and the shell mill body. It does not include through-coolant capability. Machinists and toolroom technicians use this holder in both manual and CNC knee mills as well as horizontal milling setups that accept a 4MT spindle interface.

This shell mill holder is suited for face milling and shoulder milling operations where shell mills in the 3 to 3-1/2 inch cutting diameter range are required. It is appropriate for job shop, maintenance, and production environments using machines with a Number 4 Morse taper spindle. The holder provides a positive mechanical drive when properly seated and draw-bar secured, making it a standard tooling component for general-purpose milling work.

Key Features

• 4MT (Number 4 Morse Taper) shank interfaces directly with compatible milling machine spindles

• Accepts shell mills with cutting diameter range of 3 inches to 3-1/2 inches
• No through-coolant passage — standard dry or flood coolant applications
• Weighs 2.3 pounds for stable mass at the spindle interface

Compatibility

Designed as a standard replacement or additional holder for milling machines equipped with a Number 4 Morse Taper spindle accepting shell mills in the 3 to 3-1/2 inch cutting diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before mounting or removing this holder, ensure the machine spindle is fully stopped and the machine is powered down or locked out per applicable lockout/tagout procedures. The taper shank must be clean and free of chips, burrs, or oil film before seating to ensure proper contact and runout performance. Secure the holder with the appropriate draw bar for the machine spindle before initiating any cutting operation.
