Description

The Zipp Air Tool USA ZTU391 Wire Wheel Hub is a precision-machined industrial accessory engineered to securely mount and drive wire abrasive wheels on pneumatic surface preparation tools. Built to endure the high torsional loads and rotational speeds of continuous industrial grinding and de-scaling, this hub assembly ensures vibration-free wheel retention, smooth balance, and safe operation.

Constructed from heavy-duty hardened alloy steel, the ZTU391 is designed for demanding maintenance, automotive collision repair, and metal fabrication applications. It provides quick, repeatable wire wheel changes and delivers positive drive engagement to eliminate slippage during aggressive rust removal, paint stripping, and weld cleaning across broad or contoured metallic surfaces.
