The Chicago Pneumatic 4-1/2" Angle Grinder, No. CP7545, offers a 1.1hp governed motor, which provides enough power for aggressive material removal. Power transfer to the abrasive is done through the durable bevel gearing, which also provides 1,000 hours of use between maintenance cycles. The composite-covered aluminum and steel design insulates the operator’s hand from the cold and makes it compact and lightweight at just 3.5 lbs and 10.6” long. The grinder is available in 4”, 4.5” and 5” wheel capacities, and it offers an adjustable guard and 360-degree swivel inlet.
