Dremel Multi-Max MM610 Flexible Scraper Blade. Flexible scrapers are used for hard to reach areas and removal of soft materials such as caulk. Make sure the blade is flexed during the scraping process. A 30 to 45 degree pitch is recommended. Make sure the screw head of the Multi-Max tools does not make contact with the surface being scraped. If you are removing caulk from a delicate surface such as a bath tub or wall tile, we recommend taping or protecting the surface that the blade will rest on. Blade is 1 1/8 inches wide.
