Value Collection 354064 Tapping Head Shank 4MT Taper

Product Description

The VALUE COLLECTION 354064 is a tapping head shank accessory designed to connect reversing tapping heads to machine spindles using a No. 4 Morse Taper (4MT) shank and a threaded mount interface. This holder accessory provides the mechanical link between the tapping head body and the machine tool, transmitting torque and axial load during threading operations. It is used in CNC machining centers, drill presses, and turret lathes where reversing tapping heads are already in service. Machinists and toolroom technicians are the primary installers and users of this component.

This shank is suited for production threading applications in job shops, tool rooms, and manufacturing facilities where a 4MT spindle taper is present. It is intended for use with reversing tapping heads and provides a repeatable, rigid connection for consistent thread depth and tap alignment. The threaded mount secures the tapping head body to the shank without additional tooling in most setups.

Key Features

• No. 4 Morse Taper shank for direct spindle mounting on compatible machines
• Threaded mount type for secure attachment to reversing tapping head bodies
• Designed specifically for use with reversing tapping heads
• Single-piece accessory ships individually, no additional components required for basic assembly
• Weighs 1.55 pounds for stable, low-vibration performance in the spindle

Compatibility

Designed for use with reversing tapping heads requiring a 4MT taper shank with a threaded mount interface. Specific compatible tapping head models are not identified in the available product data; verify tapping head thread specification before ordering.

Installation Notes

Installation is performed by machinists or toolroom technicians. Before mounting or removing this shank, de-energize the machine tool and engage all spindle locks per the machine manufacturer's lockout/tagout procedure. Clean both the 4MT shank and the machine spindle bore thoroughly before seating to ensure full taper contact and prevent fretting. Follow the tapping head manufacturer's instructions for attaching the head body to the threaded mount on this shank.
