Makita LXRH011 18-Volt LXT Lithium-Ion Brushless Cordless 1-Inch Rotary Hammer Kit with HEPA Vacuum Attachment (Discontinued by Manufacturer) Efficient BL Brushless motor is electronically controlled to optimize battery energy use for up to 50% longer run time per charge The BL Brushless Motor eliminates carbon brushes, enabling the BL Motor to run cooler and more efficiently for longer life The built-on vacuum attachment captures concrete dust during drilling and is activated by the tool for operator convenience Vacuum powered by separate motor to maintain tool drilling performance, and provide a 2 second delay to capture remaining concrete dust. Efficient HEPA filtration system captures 99.75% of particulates .3 microns and larger. Compact design at only 12-7/8 long weighs only 10.2lbs Variable speed trigger enables user to match the speed to application for greater versatility. Multiple Chisel Positions has 40 different positions to align tool more comfortably with the application. Torque Limiting Clutch prevents gear damage by automatically disengaging gears if the bit binds. Sequential Impact Timing provides timed hammering during rotation to minimize overlapping bit impacts resulting in up to 50% faster drilling. Jobsite tested shock absorbent handle protect the battery housing for extra durability. LXT Lithium-Ion battery and Rapid Optimum Charger produces 430% total lifetime work with 3x more cycles LXT Lithium-Ion battery provides longer run time, 5x lower self-discharge (for use any time) and 16 firm holding contact terminals (for constant high power) 30-Minute Rapid Optimum Charger communicates with the battery's built-in chip throughout the charging process to optimize battery life by actively controlling current, voltage and temperature 30-Minute Rapid Optimum Charger has a built-in fan to cool the battery to produce more lifetime work The charger earned the ENERGY STAR label for meeting the strict energy-efficient guidelines set by the US Environmental Protection Agency (EPA) and US Department of Energy (DOE) 3-year warranty on tool and 1-year warranty on battery and charger 2 ea. 18V LXT Lithium-Ion Battery (BL1830) 30-Minute Rapid Optimum Charger (DC18RA) HEPA Vacuum Attachment (DX010) Side Handle (158057-6) Depth Gauge (234219-0) Contractor Bag (821007-X) LXRH01Z LXRH01ZVX Efficient BL Brushless motor is electronically controlled to optimize battery energy use for up to 50-Percent longer run time per charge The BL Brushless Motor eliminates carbon brushes, enabling the BL Motor to run cooler and more efficiently for longer life The built-on vacuum attachment captures concrete dust during drilling and is activated by the tool for operator convenience Vacuum powered by separate motor to maintain tool drilling performance, and provide a 2 second delay to capture remaining concrete dust Sequential Impact Timing provides timed hammering during rotation to minimize overlapping bit impacts resulting in up to 50-Percent faster drilling
