The Makita with the longitudinal motor is often confused as worm drive, it's contained steel hypoid years since it hit the market when Porter Cable, Rockwell, Milwaukee, Thor, Cummins, Skil, Wappat, Speedway, Black & Decker, Van Dorn & Stanley all already had worm drive saws on the market. Most had their own recommended oil and it wouldn't be compatible with hypoid gears.
