Review on Chicago Pneumatic 8941075452 CP7545B Grinder by Carlos Reyes

840 W power, very pleasant to the touch, also with rotating air intake. Much power. Good grip ergonomics and rubber grip, perfect size diameter. The air intake rotates 360 constantly. Pretty light. Very loud, but what the heck. Wear earplugs. Some no-load vibrations at high RPM are minimal. There is no locking knob for the shaft, wrenches must be used. For my purposes the best air angle grinder; Manufacture and welding of aluminum under difficult conditions.
