Makita's 5377MG (7-1/4") magnesium hypoid saw, with a number of revolutionizing technologies, has singlehandedly established a new line of evolved circular saw. The saw's 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 saw's magnesium components keep the saw ultra-lightweight, well-balanced, and surprisingly durable. The term "hypoid" in the saw's 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. The saw has a large cutting capacity, a reinforced power cord, and performs with carbide-tipped blades to ensure the strongest, cleanest, most precise cuts. This saw is tremendous - and exciting - and delivers craftsmen a little bit of the impossible in a highly evolved power circular saw.
