Value Collection 219-3113 End Mill Holder 3MT Taper

Product Description

The VALUE COLLECTION 219-3113 is a 3MT taper shank end mill holder designed to secure end mills in milling machines and machining centers. The holder features a 1/4-inch bore diameter and a 1/2-13 drawbar thread, providing a rigid mechanical connection between the spindle and cutting tool. Through-coolant is not supported. Machinists and toolroom technicians rely on this style of holder for accurate, repeatable tool positioning during milling, slotting, and profiling operations. The Morse taper shank seats directly into compatible spindle bores, allowing fast tool changes without additional adapters.

This end mill holder is suited for use in manual knee mills, vertical machining centers, and drill-mill machines equipped with a No. 3 Morse taper spindle. It is appropriate for light-duty to medium-duty milling applications in job shops, maintenance facilities, and production environments where 1/4-inch shank end mills are commonly run. The 1/2-13 drawbar thread keeps the holder firmly seated during cutting loads.

Key Features

• 3MT (No. 3 Morse Taper) shank seats directly into matching spindle bores
• 1/4-inch bore diameter accommodates standard 1/4-inch shank end mills
• 1/2-13 drawbar thread for secure spindle retention
• No through-coolant passage, keeping the design simple and straightforward
• Compact, single-piece holder construction for rigid tool support

Compatibility

Designed as an OEM-style replacement or standard tooling addition for milling machines and machining centers equipped with a No. 3 Morse taper spindle and a 1/2-13 drawbar thread.

Installation Notes

Installation is performed by a machinist or toolroom technician. Before changing tooling, power down the machine and ensure the spindle is fully stopped. Clean both the Morse taper shank and the spindle bore thoroughly before seating to prevent fretting and ensure proper contact. Tighten the drawbar to the machine manufacturer's specified torque using the appropriate wrench, and verify the end mill set screw is secured before resuming operation.
