2-14" DeWalt DW8500 Diamond Chop Saw Blades. 1" arbor, 3/32" thick. CHECK out the original cost of these! I used them in a gas powered cut-off saw. A MUST for Tile cutting where chipping is a concern They will cut thru about anything, including pipe, steel studs, angle iron, rebar, threaded rod, plastic, fiberglass, rubber, brick, tile or concrete. Lifespan is 100x's greater than regular blades. Bought several for a project but because they lasted so long I didn't need the last 2. They are New in package. My loss, your gain. Both for $160
