More cordless circular saws are now available in high-voltage variants that allow workers to cut lumber with roughly the same speed and torque as a corded saw; however, few use a full-size, 7-1/4-in.-dia blade. DeWalt's 36-volt saw is one, but it requires stepping up to a 36-volt battery that is compatible with only certain tools and chargers.
Makita takes a different path to power on its new XSH01X circular saw. Instead of using one 36-volt battery, Makita's side-motor saw accepts two 18-volt lithium-ion batteries. This configuration allows workers to mix and match between a wider range of tools and chargers. According to the firm, the saw makes an average of 250 crosscuts in 2x4 lumber on each charge.
