The Bosch HS1918RK Replacement Kit includes a replacement blade, bolts, nuts and washers for the HS1918 SDS-max® Floor Scraper. The scraper features a durable steel blade, which provides long life in mortar and tile removal. It has stable blade attachment with secure bolt-and-nut fasteners for strong blade attachment and resistance to vibrating loose. The wide 6 In. blade delivers significant material removal, while the long shank allows the user to do more upright scraping for greater ergonomics. It can be used for tile removal, mortar removal, and laminate floor and laminate glue removal.
