Arc Abrasives 50259 Quick-change Abrasive Holder 2x1/4 in Medium

Product Description

The ARC ABRASIVES 50259 is a QLOK-style quick-change abrasive holder designed for use with compatible quick-change abrasive discs and surface conditioning products. Measuring 2 inches in diameter with a 1/4-inch shank, this medium-density holder mounts to pneumatic or electric rotary tools and allows rapid disc swaps without removing the holder from the tool. It is sold individually and is a standard component in metal fabrication, weld prep, and surface finishing workflows handled by machinists, fabricators, and maintenance technicians.

This holder is suited for production and maintenance environments where frequent abrasive changeover is required. The quick-change mechanism reduces tool downtime by enabling fast product swaps mid-task without additional tooling. It is commonly used in metalworking shops, fabrication facilities, and field maintenance settings where surface preparation, deburring, or blending operations are performed on steel, aluminum, and other workpiece materials.

Key Features

• QLOK quick-change mechanism enables fast abrasive disc changeover without secondary tools
• 2-inch diameter with 1/4-inch shank for compatibility with standard rotary tool chucks
• Medium density construction suited for general-purpose surface conditioning
• Lightweight at 0.1 pounds, reducing operator fatigue during extended use
• Sold individually, allowing targeted replacement without excess inventory

Compatibility

Designed as an OEM-style holder for use with 2-inch quick-change abrasive discs in QLOK-compatible systems. Refer to manufacturer documentation for confirmed disc and backing pad compatibility.

Installation Notes

Installation is performed by machinists or fabricators using standard rotary tools accepting a 1/4-inch shank. Ensure the rotary tool is fully powered off and disconnected from the air supply or power source before attaching or removing the holder. Verify the shank is fully seated and locked in the tool chuck before operating. Follow applicable ANSI abrasive safety standards and tool manufacturer guidelines for maximum RPM ratings.
