The Metabo HPT RSEV 17-125 is a 5 in. variable-speed renovation grinder for concrete. Metabo HPT describes it as a professional-grade tool made in Germany for removing tough coatings from a variety of surfaces, and as widely used in construction and renovation for leveling, shaping and smoothing floors and walls before painting or tiling. A 14.5 amp LongLife motor delivers speeds from 2,800 to 9,600 RPM, with soft start, speed stabilization, electronic overload protection and restart protection. A mechanical S-Automatic clutch decouples the drive if the tool stops unexpectedly, and the low-vibration VibraTech (MVT) side handle reduces vibration (Amazon's listing says by up to 60%). The anti-static suction guard supports low-dust grinding indoors and outdoors and can be removed without tools for use as an angle grinder with a guard. The tool weighs 6 lbs. The set includes the grinder, a 5 in. diamond cup wheel, the convertible dustless guard, the side handle, a spanner wrench and a metaBOX case, and the tool body carries a 3-year warranty. • 5 in. diamond cup wheel; 14.5 amp LongLife motor; 2,800-9,600 RPM • Soft start, Vario-Tacho-Constamatic speed control, electronic overload protection, restart protection • S-Automatic mechanical safety clutch • VibraTech (MVT) low-vibration side handle • Anti-static suction guard for low-dust grinding; removable without tools • 6 lbs; 3-year tool body warranty • Applications: concrete, screed and coatings
