TOPICS FOR SPEAKING

They are usually made of Vanadium electric steel or high-grade tool steel. Cutting edges are induction hardened. Scrapers are made in many forms and are used for removing paint, glue, varnish and rust on a wide variety of surfaces. Flat scraper should be used for scraping and removing high spots from flat surfaces; the 3-corner scraper is provided with small triangular blade which allows access to small, confined areas and is commonly used for removing burrs or sharp internal edges from soft bushings. Dies are used for threading a round stock. Before threading a piece of round stock its end should be tapered or chamfered slightly with a file, or by grinding, so that the die will start cutting more easily.
