The Metal Edge Products Lug Ripper offers users a fast and easy way to remove seized, rusted, frozen and stripped lug nuts without damaging the rim. Precision-machined guides protect wheel rims while a carbide steel cutting bit mills away lug nuts from the inside. Utilizing a low-speed drill, the Lug Ripper only takes minutes to cut away the threads and remove the lug nut. The Lug Ripper comes with three sizes of protective guides including 17mm, 19mm and 21mm to fit the most common domestic and import vehicles and trailers. The kit includes a collar clamp and rubber spacing wedge for deep reccessed lugs.
