Value Collection 219-4015 End Mill Holder 4MT 3/8 Inch

Product Description

The VALUE COLLECTION 219-4015 is a Morse taper end mill holder designed to secure end mills in milling machines and machining centers. The holder features a 4MT taper shank for direct spindle mounting and a 3/8 inch bore with a 1.87 inch projection from the spindle face to the tool seat. This combination of taper size and projection length suits a wide range of milling operations in job shop and production environments. Machinists and toolroom technicians install this holder when setting up end mills that require a rigid, concentric grip on a standard Morse taper spindle.

This end mill holder is suited for use in manual knee mills, vertical milling machines, and compatible machining centers equipped with a 4MT spindle. It accepts end mills with a 3/8 inch shank diameter. The 1.87 inch projection keeps the cutting tool close to the spindle nose, supporting rigidity during side milling, slotting, and profiling cuts. It does not include through-coolant capability, making it appropriate for dry or flood-coolant external delivery setups.

Key Features

• 4MT Morse taper shank for direct mounting in 4MT spindles
• 3/8 inch bore diameter accommodates standard end mill shanks
• 1.87 inch projection (47.50 mm) from spindle face to tool seat

Compatibility

Designed as an OEM-style replacement or standard tooling addition for milling machines and machining centers with a 4 Morse taper spindle and requiring a 3/8 inch end mill holder.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine spindle before mounting or removing the holder. Clean the spindle bore and taper shank thoroughly to remove chips, oil film, and debris before seating — any contamination will affect runout. Use a draw bar or appropriate drift and mallet as required by the machine design to seat or release the taper; never strike the cutting tool or the holder body directly.
