The 18V LXT? Lithium-Ion Cordless 16 Gauge Nibbler (model XNJ01Z, tool only) provides contractors with another 18V LXT? metal cutting solution. The XNJ01Z is engineered for cutting corrugate metal roof decking, sheet metal, and stainless steel, and it will do the job without the cord. It is ideal for metal roofing and decking contractors, HVAC, and metal fab shop work.It?s part of Makita?s expanding 18V Lithium-Ion series, the world?s largest cordless tool line-up powered by an 18V Lithium-Ion slide-style battery. Makita 18V Lithium-Ion 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.The XNJ01Z is powered by a Makita-built motor that delivers 1,900 strokes-per-minute (SPM) for fast and smooth cutting. The die holder rotates 360? to meet the demands of the cutting direction, with a cutting radius of 1-3/4? (inner edge) and 2? (outer edge). When cutting, the metal chips are conveniently disposed below the cutting material, which helps prevent damage to the work surface.
