The Worx MAKERX Rotary Tool Accessory Kit with 201 Pieces comes with every accessory you need to do pretty much every one of the most popular rotary tool applications. Engrave glass, wood, and metal. Cut off protruding bolts, grind rust off iron rails before painting, sand children’s toys, or polish a brass nameplate while it’s still mounted.
