This new 7-1/4″ saw from Makita looks very similar to their other circular saw offerings, and to most other brands on the market, too. But it hides its special feature on the inside — a hypoid gear drive.
A hypoid gear drive is similar in design to the worm gear drive found on most other circular saws, but they differ in a couple of ways. The hypoid drive runs on a heat-treated finer-toothed gear, increasing the surface contact ratio and allowing for better power transfer and a cooler drive system. The hypoid gear is also sealed and factory lubricated, where a worm gear drive requires periodic oiling for maintenance. Makita claims that because of these two factors their saw cuts thicker and lasts longer than the competition.
Aside from the hypoid gear drive, this saw sports all the usual specs you’d expect from a Makita product: 15A motor, 2-3/8″ cutting capacity at 90 degrees, push-button spindle lock, heavy-duty aluminum base plate, externally serviceable brushes, and a 24T thin-kerf carbide-tipped blade.
Street pricing is around $120.
