Value Collection 219-3017 End Mill Holder 3MT 5/8 in

Product Description

The VALUE COLLECTION 219-3017 is a taper shank end mill holder designed to secure end mills in milling machine spindles and machining center setups. Built around a 3MT (Morse Taper 3) shank, it accepts end mills with a 5/8-inch bore and delivers a projection of 2.992 inches from the spindle face to the tool cutting end. The holder provides a rigid, concentric connection between the machine spindle and the cutting tool, reducing runout and maintaining dimensional accuracy during milling operations. Machinists and toolroom technicians install this holder in manual knee mills and CNC machining centers equipped with a Morse Taper 3 spindle. Through-coolant is not supported.

This holder is suited for light-to-medium milling work in job shops, toolrooms, and production environments where a Morse Taper 3 spindle interface is used. The 5/8-inch hole diameter accommodates standard end mill shank sizes commonly used in general-purpose milling. The 2.992-inch projection provides clearance for a range of workpiece heights and fixturing configurations. It is installed by a machinist or CNC setup technician during tool change or spindle tooling setup procedures.

Key Features

• 3MT (Morse Taper 3) shank for direct spindle mounting without an adapter
• 5/8-inch hole diameter fits standard end mill shank sizes
• 2.992-inch projection provides tooling clearance over workpieces and fixtures
• Rigid shank-to-tool connection reduces runout during milling operations
• No through-coolant port — suited for dry or external coolant applications

Compatibility

Designed as an OEM-style replacement or tooling addition for milling machines and machining centers equipped with a Morse Taper 3 spindle and requiring a 5/8-inch end mill holder.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. Power down and lock out the machine spindle before removing or installing any tooling. Ensure the taper shank and spindle bore are clean and free of chips, oil, or burrs before seating the holder to achieve full contact and minimize runout. A drawbar or retention knob appropriate to the machine must be used to secure the holder in the spindle.
