Dura-BULL 6" flat lap system. Use this complete horizontal flat lap system to grind flats, re-work quartz crystals, or make free-form cabochons. It is also well-suited for cutting, shaping, and polishing glass. Powered by a variable-speed ball-bearing DC motor with a built-in 115-volt AC converter, this machine is quiet enough to be used in the smallest shop, in the home studio, even in a trailer or RV. A coolant reservoir holds approximately one pint of water (enough to keep you working for up to 2-3 hours) to prevent heat build-up and help remove dust; a splash guard keeps the water off your work clothes and on your work piece, where it can do the most good. The lightweight, impact-resistant body will not rust and is a breeze to clean just remove the water spray shield and tray, wash, and you are ready to work again. An accessory kit is included with the machine that allows you to work right out of the box. Grind, shape and polish a wide variety of natural and synthetic gemstone materials as well as glass and enamels. The kit contains: one 180-mesh metal bond diamond disc, one 325-mesh diamond smoothing disc, one 600-mesh diamond smoothing disc, one 1200-mesh diamond smoothing disc, one Tech-10 polishing pad with 14,000-mesh diamond compound, four disc backing plates, complete instructions. Power: 110-120 volts.
