The Makita 18V LXT® Lithium-Ion Recipro Saw (tool only) combines cutting speed with convenience features for faster, more efficient cutting. It’s powered by the industry’s fastest charging 18V lithium-ion batteries (sold separately), allowing users to remain in one battery platform and use the same fast-charging 18V batteries on the XRJ04Z as they use across the Makita 18V LXT® cordless tool line-up. The XRJ04Z is equipped with efficiency features for faster cutting. The long 1-1/4″ stroke length increases cutting efficiency, and the refined crank mechanism design minimizes blade deflection and reduces vibration. Convenience features include a large two-finger variable speed trigger, electric brake, and “tool-less” blade change for faster blade installation and removal.
