Arc Abrasives 50401Z2 Qlok Holder 5/8-11 Medium

Product Description

The ARC ABRASIVES 50401Z2 is a QLOK quick-change holder designed for use with abrasive discs and flap wheels in grinding and finishing applications. The holder accepts a standard 5/8-11 threaded arbor and is rated for medium-duty use. Its quick-change mechanism allows operators to swap abrasive products rapidly without extended downtime, making it well suited for production environments where multiple grits or disc types are cycled through during a single job. Metal fabricators, weld prep technicians, and surface finishing tradespeople are the primary users of this type of holder.

This holder is appropriate for use with angle grinders and other rotary tools equipped with a 5/8-11 threaded spindle. It is suited for medium-duty material removal, blending, and finishing work on metal surfaces in both shop and field settings. The quick-change interface reduces changeover time compared to conventional threaded or flanged mounting systems, which is a practical advantage during high-volume or time-sensitive finishing work.
