Lightweight and compact design makes this model particularly suitable for finish scraping of cast steel, cast iron, brass and way-liner material. Our all-purpose model for medium to smaller work.
Applications: Used on applications where pneumatic power is desired or necessary (danger of explosion). Same applications as the 7ELM/BL-40 model. Single stroke speed. Often used for special applications in chemical, plastics and food industries to scrape off hardened resin or coating residue, etc. Muffler/air silencer not included. * Available on request.
Applications: Scraping/flaking of half-moon oil-pocket patterns for slide way lubrication, or to break up friction and "stick-slip" on precision-machined flat surfaces and ways. Pattern creates pleasing appearance and ensures good surface lubrication with better wear characteristics. Rescraping of worn ways to reestablish lubrication and prevent further wear. Our "Flaker" or "Spotter" model.
