Returns Simplified.The Makita brushless cordless 1-1/8 Inch rotary hammer kit contains a rotary hammer, a side handle, cloth towel, battery, grease, tool bag and an optimum charger. Hammer works well with SDS-plus bits and is ideal for heavy-duty applications. XGT technology produces up to 135 of 3/8 Inch holes per charge on a single battery. Brushless motor operates at an impact energy of 2.8 ft-lb and has a speed of 0 to 980 RPM and 0 to 5000 BPM. Constant speed mechanism automatically applies the power under load. Active feedback-sensing technology electronically shuts down the motor in case the rotation of the bits if stopped suddenly. Anti-vibration technology minimizes the vibration on the padded handle thus making it easier to use. Internal counterbalancing technology moves the counterweight positions in the opposite direction of the drive piston by utilizing the air pressure. Auto-Wireless technology makes use of Bluetooth connectivity for effortless wireless communication between the equipped tool and the dust extractor. Dust extractor automatically starts when the tool is running and stops immediately when the tool is stopped. This in turns enhances the productivity and minimizes the continuous noise at the jobsite. Torque-limiting clutch disengages the gears if the bits binds thus preventing any gear damage. Electric brake prevents sudden initiation and the integrated LED light brightens up the working surface. Overload protection safeguards the motor from burnout while using the tool in high-torque applications. User can choose three operational modes namely “rotation only”, “hammering with rotation” and “hammering only” depending upon the applications. Extreme protection mechanism provides good resistance to dust and water in harsh weather conditions.
Power & Efficiency 40VMax XGT brushless motor delivers strong drilling performance with up to ~23% faster concrete drilling and ~38% more holes per charge vs previous generations ideal for commercial concrete work.
JobSite Comfort AntiVibration Technology (AVT) reduces felt vibration significantly, improving operator comfort during prolonged drilling and chiseling tasks.
Smart Safety & Control Active FeedbackSensing Technology (AFT) shuts down the motor if the bit binds, reducing kickback risk and protecting both user and tool.
Dust Management Ready Capable of connecting to OSHA Table1 compliant HEPA dust extractors (sold separately), supporting cleaner, safer work environments.
DHandle Design Ergonomic Dhandle configuration makes overhead and downward drilling easier, increasing versatility on varied job situations.
Complete Kit Value Includes 4.0Ah battery, rapid charger, side handle and accessories ready to tackle concrete drilling out of the box.
Pro Tip: Pair with quality SDSPLUS bits and an AWScapable dust extraction setup to maximize efficiency and maintain clean workspaces.

A: It combines brushless motor efficiency, AntiVibration Technology (AVT) for comfort, Active FeedbackSensing Technology (AFT) for safety, and cordless convenience for professional use.
Clean tool after each use wipe down the hammer and remove concrete dust/debris from vents and bit area to prevent buildup and overheating.
Inspect SDSPLUS bits check bits for wear or damage and replace them as needed for efficient drilling.
Apply bit grease use the included hammer bit grease on the bit shank before use to reduce friction and extend bit/chuck life.
Keep battery contacts clean wipe XGT battery and tool terminals dry to ensure solid power transfer and prevent corrosion.
Clear cooling vents remove debris around vents to maintain airflow and prevent brushless motor heat buildup.
Tighten handles & fasteners check side handle and screws before operation to avoid loosening from vibration.
Use dust extraction (optional) if connecting a HEPA dust extractor, empty/clean filters often to preserve airflow and suction.
Store dry & cool keep the rotary hammer and batteries in a dry, climatecontrolled place away from moisture/extreme temperatures.
