The 18V X2 LXT® Lithium-Ion (36V) Cordless 7-1/4" Circular Saw (model XSH01PT) is the world’s first cordless 7-1/4" circular saw powered by two 18V batteries. The XSH01PT provides the performance of a corded saw without leaving the strongly-preferred 18V platform. It’s part of Makita’s expanding 18V LXT® series, the world’s largest cordless tool system powered by 18V Lithium-Ion batteries. Makita 18V LXT® batteries have the fastest charge times in their categories, so they spend more time working and less time sitting on the charger. For improved tool performance and extended battery life, Makita created Star Protection Computer Controls™. Star Protection is communication technology that allows the Star Protection-equipped tool and battery to exchange data in real time and monitor conditions during use to protect against overloading, over-discharging and overheating. For increased versatility, the tool can also be powered by Makita 18V LXT® and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside. Longer Run Time The Makita-built motor delivers 4,800 RPM for fast cutting and ripping. In performance testing the XSH01PT/Z made 250 cuts in 2x4 lumber per charge**, which is up to 2.5 times more cuts per charge than the Makita 18V Cordless 6-1/2" Circular Saw, model BSS611Z. More Capacity, Fast Cutting With a 7-1/4" blade the XSH01PT/Z has a cutting capacity of 2-5/8" at 90 degrees. In side-by-side testing the XSH01PT/Z exhibited corded power and speed, cross-cutting a 2x10 in only 1.5 seconds and matching the cutting time of the Makita 5007F corded circular saw. More Features, Less Weight Model XSH01PT/Z has a reinforced magnesium base for added durability and weighs only 10.1 lbs. (with batteries). The saw includes two L.E.D. indicators that monitor battery charge status and temperature. Additional features include an electric brake for maximum productivity, rubberized soft grip handles for increased comfort, and a built-in dust blower engineered to clear the line-of-cut for improved visibility.
