Value Collection 219-4017 End Mill Holder 4MT Taper Shank

Product Description

The VALUE COLLECTION 219-4017 is a 4MT taper shank end mill holder designed for use on manual and CNC milling machines, machining centers, and drill presses equipped with a Morse taper spindle. The holder accepts a 5/8 inch bore and delivers a 2.264 inch projection from the spindle face to the tool seat, providing a consistent and rigid tool-holding interface. This style of holder is a standard component in production and job-shop environments where repeatable tool positioning is required. Installation is performed by qualified machinists and toolroom technicians.

This end mill holder is suited for vertical and horizontal milling applications where a 4MT spindle interface is present. The 5/8 inch hole diameter accommodates straight-shank end mills of that size. The 2.264 inch projection suits setups where moderate tool extension is needed without excessive overhang. No through-coolant capability is present on this holder, making it appropriate for dry or flood-coolant applications where coolant is directed externally.

Key Features

• 4MT Morse taper shank for direct spindle mounting without an adapter
• 5/8 inch bore diameter for straight-shank end mills
• 2.264 inch projection (57.50 mm) from spindle face to tool seat
• No through-coolant port — compatible with external flood or dry cutting
• Compact and lightweight at 0.75 pounds for minimal spindle load

Compatibility

Designed as a standard OEM-style replacement or addition for milling machines and machining centers equipped with a 4MT (Number 4 Morse Taper) spindle bore and requiring a 5/8 inch straight-shank end mill interface.

Installation Notes

Installation and removal should be performed by a qualified machinist with the machine powered down and all motion fully stopped. A drawbar or drift punch of the appropriate size is typically required to seat or release the Morse taper. Inspect the taper shank and spindle bore for nicks, burrs, or contamination before seating to ensure full contact and prevent runout. Consult the machine tool manufacturer's documentation for drawbar torque and retention specifications.
