Makita created a new class in cordless with 18V LXT? Sub-Compact tools. Makita Sub-Compact gives users 12V handling with 18V performance, and compatibility with the world?s largest 18V cordless tool system. The XRJ07R1B is a sub-compact solution for cutting and demolition applications in tight spaces. The Sub-Compact Recipro Saw has a compact and ergonomic design at only 12-1/2? and 5.7 lbs. (with 18V LXT? Compact 2.0Ah battery). The compact size makes it ideal for work in tight spaces and is a welcome solution for plumbers, electricians, and more. Convenience features include ?tool-less? blade change, a reinforced fixed show for added durability, electric brake, and a built-in L.E.D. light for improved visibility. It?s equipped with Extreme Protection Technology (XPT?), which is engineered for improved dust and water resistance for operation in harsh conditions. It?s part of Makita?s expanding 18V LXT? system, 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.
