Expand Your Grinder's Capabilities

Every welder knows the frustration of having the perfect wire wheel or abrasive disc for a job, only to find out the threads don't match the grinder on hand. The Walter 13D004 Adapter is the simple, rugged solution to that problem. It instantly transforms your standard angle grinder's 5/8"-11 spindle into a 3/8"-16 mount, opening up a whole new range of accessory options for your shop. Whether you are trying to mount a specific cup brush, a smaller flap wheel, or a specialty finishing drum, this adapter makes it happen without the need to buy a completely new tool.

Built tough for the welding shop, this isn't a cheap hardware store part. It is a heavy-duty steel adapter designed to handle the heat, speed, and abuse of daily metalworking.
