The 18-Volt LXT Lithium-Ion Cordless 20 oz. Barrel Style Caulk and Adhesive Gun (model XGC01ZB, tool only) is a versatile, powerful lightweight solution for any contractor dispensing large amounts of caulk and adhesives. Its part of Makita's expanding 18-Volt Lithium-Ion series, the world's largest cordless tool line-up powered by 18-Volt Lithium-Ion slide-style battery. Makita 18-Volt 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 18-Volt LXT and Compact Lithium-Ion batteries with the star symbol on the battery indicating Star Protection inside. The XGC01ZB delivers 1,100 lbs. of dispensing force for even the highest viscosity adhesives and sealants. The XGC01ZB features a 5-speed dial (0-66 IPM) and variable speed trigger that optimizes flow rate and allows for faster dispensing. It has a compact design at 21-1/4 in. with less weight (only 6.0 lbs. with 18-Volt LXT battery, sold separately).
