Cory from Dremel gives you a quick EZ Lock Grinding Wheel tutorial. I want to review the new EZ Lock grinding wheel. THese unique one and half inch dimater ginrding wheels are dome shaped and double reinforced with aluminim oxide to last five times longer than the Dremel 541 accesory. What's really great about this is that you can use the face of accessory for surface grinding, sharpening, and for use on welded joints. Now we'll show you a demo with the EZ Lock working with the Dremel 4200 cordless tool to cut off an exposed to and grind flush. For info on this tool and other Dremel tools, please visit Dremel.com.
