Value Collection 417 Screw Lock Wheel Mandrel

Product Description

The VALUE COLLECTION 417 is a screw lock wheel mandrel designed to mount abrasive finishing wheels onto rotary tools and die grinders. The mandrel accepts wheels with a 0.375 inch center hole and is driven by a 0.25 inch shank that seats into standard collet-style rotary tool chucks. Overall length measures 2.0625 inches. The screw lock design uses a threaded fastener to secure the wheel in place, providing a firm mechanical connection that resists loosening under rotational load. Machinists, metalworkers, and maintenance technicians typically use this type of mandrel for deburring, grinding, and finishing work on metal and composite surfaces.

This mandrel is suited for bench-top and handheld rotary tool applications in fabrication shops, maintenance facilities, and general manufacturing environments. It is compatible with abrasive wheels that feature a 0.375 inch mounting hole. The 0.25 inch shank fits the majority of standard die grinder chucks and rotary tool collets commonly used in trade and industrial settings. The screw lock retention method makes wheel changes straightforward and repeatable during production or service work.

Installation Notes

Installation is performed by metalworking and maintenance trade professionals using standard rotary tool equipment. Before mounting or removing the wheel, ensure the rotary tool or die grinder is powered off and disconnected from its power source. Thread the abrasive wheel onto the mandrel and tighten the screw lock fastener securely before operation. Follow the wheel manufacturer's rated RPM and the tool manufacturer's speed specifications to avoid wheel failure.
