unique problem with hardwood floor

jgipp

Diamond blade on a 3 1/2 inch grinder. We bought it for grinding flex off concrete, a 6 inch grinder proved better for whole rooms, but the small one worked pretty well for removing just enough doorjamb for tile, lot better than a doorjamb saw. Used it a few times for taking out some other wood. Smokes a bit, but does the job.
