Value Collection M-22 Screw Lock Wheel Disc Mandrel

Product Description

The VALUE COLLECTION M-22 is a screw lock wheel disc mandrel designed to mount abrasive disc wheels on rotary tools, die grinders, and bench grinders. It accepts wheels with a 1/4 inch center hole and accommodates a maximum wheel width of 1/4 inch. The shank diameter is 1/4 inch, making it compatible with standard 1/4 inch collets and chucks. Overall length is 2 inches. The screw lock connector type secures the wheel firmly during operation, reducing vibration and wheel slippage. Weighing 0.2 pounds, this mandrel is a lightweight, single-piece accessory suited for metalworking, deburring, and surface preparation tasks performed by machinists, tool and die workers, and maintenance technicians.

This mandrel is used in shop environments where abrasive disc wheels must be chucked into a rotary power tool for grinding, blending, or finishing operations. Typical applications include deburring metal edges, cleaning weld seams, and surface preparation on ferrous and non-ferrous materials. The 3/4 inch head and washer diameter provides adequate clamping surface for small-diameter disc wheels. It is sold as a single unit and is appropriate for both production shop use and general maintenance work.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard hand tools. Ensure the rotary tool or die grinder is powered off and unplugged before mounting or removing the mandrel. Thread the disc wheel onto the screw lock fastener and tighten securely before operation to prevent wheel separation. Confirm the shank seats fully in the collet and the collet nut is tightened to the tool manufacturer's specification before running the tool.
