The Makita 18V LXT Lithium-Ion Cordless 6-1/2? Circular Saw delivers cordless cutting power to the job site. The XSS02Z has a Makita-built high-torque motor and a compact design for a range of cutting applications. It will cut 2X material at 45 degrees. The Makita-built high torque motor produces 3,700 RPM for faster cutting. The heavy gauge, precision machined base is engineered for smooth, accurate cutting and added durability in harsh job site conditions. The Makita 18V LXT Lithium-Ion battery charges faster and works longer than standard lithium-ion batteries, giving you and your cordless tools unmatched performance and productivity to take on the most demanding applications. The Makita 5.0Ah battery, model BL1850B, combines more run time (65% more run time per charge than the Makita BL1830 battery) with a category-leading charge time of only 45 minutes, so it spends more time working and less time sitting on the charger. For added convenience, it also features an onboard L.E.D. charge level indicator to monitor battery charge.
