Value Collection M-32-L Screw Lock Wheel Mandrel

Product Description

The VALUE COLLECTION M-32-L is a screw lock wheel mandrel designed to mount abrasive grinding wheels and cut-off wheels onto rotary tools, die grinders, and bench grinders. The mandrel accepts wheels with a 1/4 inch center hole and secures them with a screw lock mechanism for positive retention during operation. The shank diameter measures 3/8 inches, the overall length is 2 inches, and the head or washer diameter is 3/4 inches. This type of mandrel is a standard shop consumable installed by machinists, tool-and-die workers, and maintenance technicians across light manufacturing and fabrication environments.

This mandrel is suited for use with small abrasive wheels in bench-top and handheld rotary applications. It is a practical fit for tool grinding, deburring, and surface prep tasks where a secure wheel mount is required. Compatible wheel widths range from 3/8 inches minimum to 1/2 inches maximum, keeping the setup stable under lateral load during grinding passes. The screw lock design allows quick wheel changes without special tooling.
