Hilti's DCH 230 and 300 Electric Diamond Cutters, designed exclusively for cutting, feature a 2.6-kw motor and new cutting depth adjustment mechanism. While conventional angle grinders both grind and cut to little more than 2 in., these cutters cut to 3.4 and 4.7 in. respectively—almost twice as deep. Hilti Smart Power regulates motor power and pressure to suit the material being cut—even the toughest, thickest materials such as reinforced concrete, granite curbstone, slabs, bricks, metal beams, and steel pipes. Direct attachment of a vacuum cleaner facilitates nearly dustless cutting. Hilti Inc. 800-879-8000.
