Makitas 5377MG (7-1/4") magnesium hypoid saw with a number of revolutionizing technologies has singlehandedly established a new line of evolved circular saw. The saws motor is not only immensely powerful (2300 W) but also features a compressed winding technology keeping the overall size of the motor compact and durable. The saws magnesium components keep the saw ultra-lightweight well-balanced and surprisingly durable. The term "hypoid" in the saws name refers to its heat treated hypoid steel gears. These wickedly efficient gears are hardly as susceptible to standard wear as are traditional bronze-alloy worm drive gears. Additionally the tool incorporates an oil bath technology designed with a sealed gear housing and a built-in fan to ensure a complete oil surface coating; ultimately the hypoid gears are terribly efficient with more power and suave than traditional worm drive gears and with the help of the oil bath they are nearly maintenance free.
If you are buying a corded model I would go with a 7 1/4" and for cordless go with a 6 1/2". The larger blade models are heavier but in the long run you will have to make less cuts especially on angle cuts. Shaft Locks - Make sure your saw has a lock. A Shaft lock is usually a button you press that holds the blade still making changing the blade easier. If your buying a professional power circular saw it should have this feature.
