This scraper has a 66 long solid steel body that provides the weight necessary to force through and scrape up glued-down flooring materials. The welded blade carrier is beveled to deflect material build-up, and case hardened to reduce bending. Comes with an extremely sharp two inch wide .090 thick high carbon steel blade that holds its edge and withstands impact. Blades are replaceable using the two heavy-duty flush mount7/16 carriage nuts and bolts. Replacement blades: No. 231 2 or No. 232 3.
