Review on Carbide JESTUOUS Diameter Grinder Grinding by Matthew Ciula

I recently bought an RV and one of the previous owner's neurosurgeons made a feeble attempt to mount the spare tire directly to the rear bumper. I bought a tire mount which in turn bolts to the bumper, but of course the holes the previous owner drilled didn't let me easily drill new bolt holes to attach the tire mount. I bought this set of carbide bits to modify previous holes so I could use them as mounting points for my bracket. The Beats worked great and are ready for the next step.
