Value Collection 220-1544 Boring Head MT4 Taper Shank

Product Description

The VALUE COLLECTION 220-1544 is a boring head taper shank designed for use with MT4 Morse taper spindles and featuring a 1-1/2-18 threaded mount. This shank serves as the interface between a boring head and a machine tool spindle, transmitting rotational force and maintaining precise concentricity during boring operations. Weighing 2.33 pounds, it is a solid, purpose-built component intended for machinists and toolroom technicians working on manual or CNC knee mills, Bridgeport-style machines, and similar equipment with MT4 spindles. Coolant-through capability is not included in this design.

This taper shank is suited for light to medium boring applications in metalworking and general machining environments. It is typically used when a boring head must be mounted to a Morse taper spindle rather than a CAT or R8 spindle. The 1-1/2-18 threaded mount accepts compatible boring head bodies that use the same thread specification. It is appropriate for job shop, tool and die, and maintenance machining setups where MT4 tooling is standard.

Key Features

• MT4 Morse taper shank for direct spindle mounting without an adapter
• 1-1/2-18 threaded mount for secure boring head attachment
• No coolant-through passages, keeping the design simple and robust
• Weighs 2.33 pounds for a solid, vibration-resistant connection
• Compatible with standard boring head bodies using 1-1/2-18 thread

Compatibility

Designed for use with boring heads that accept a 1-1/2-18 threaded mount shank, installed in machine tool spindles with an MT4 Morse taper bore.

Installation Notes

Installation is performed by qualified machinists or toolroom personnel. Power down and lock out the machine spindle before seating or removing the taper shank. Clean both the spindle bore and the taper shank thoroughly before installation to ensure full contact and prevent fretting. A draw bar is typically required to secure Morse taper tooling in vertical milling applications; verify draw bar thread compatibility before installing.
