Arc Abrasives 50254 Quick-change Disc Holder 3x1/4 in Medium

Product Description

The ARC ABRASIVES 50254 is a QLOK-style quick-change abrasive disc holder designed for fast disc swaps in grinding, blending, and surface preparation applications. Measuring 3 inches in diameter with a 1/4-inch shank, this medium-grade holder accepts compatible quick-change discs and mounts directly to air-powered or electric die grinders. The quick-change mechanism eliminates the need for additional tools during disc changeover, reducing downtime on the job. It is sold individually and is a standard component in metal fabrication and finishing setups used by welders, pipefitters, and maintenance technicians.

This holder is suited for use in residential, commercial, and industrial settings where repeated abrasive disc changes are required. Common applications include weld seam blending, rust removal, deburring, and surface conditioning on metal substrates. The 3-inch diameter and 1/4-inch shank make it compatible with standard die grinder collets found across most air tool platforms. Medium designation indicates a mid-range holding tension appropriate for general-purpose disc work.
