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 \u003cspan style=\"font-size: 14px;\"\u003ebind\u003c\/span\u003e thus preventing any gear damage. Electric brake prevents sudden \u003cspan style=\"font-size: 14px;\"\u003einitiation,\u003c\/span\u003e and the integrated LED light brightens up the working surface. Retractable tool hook allows the user to store the tool when not in use. This tool is perfect for contractors, concrete contractors, road and bridge contractors, utility workers, pest control and maintenance operations. 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.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch5\u003eFeatures\u003c\/h5\u003e\n\u003cdiv class=\"attribute-values\"\u003e\n\u003cul\u003e\n\u003cli\u003e\u003cspan\u003eOUTPOWER: Makita-built brushless motor along with 40V max XGT battery combine to deliver the power performance required for heavy-load application.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOUTSMART: Constant speed control automatically applies additional power under load for optimum performance.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOUTLAST: Overload protection is designed to protect the motor from burnout in abnormally high torque situations.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eActive Feedback-Sensing Technology (AFT) electronically turns off the motor if rotation of bit is suddenly forced to stop.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAnti-Vibration Technology (AVT) is designed to reduce vibration for increased comfort.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eDust extraction capability with OSHA Table 1 compliant on-board HEPA Dust Extractor or optional stand-alone AWS Extractor.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eAuto-Start Wireless System (AWS) which utilizes Bluetooth technology for wireless power-on\/off communication between tool and dust extractor (AWS Transmitter sold separately).\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eMakita 40V max XGT 1 1\/8\" AVT Rotary Hammer Kit with Dust Extractor accepts SDS PLUS AFT AWS Capable.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eTorque limiting clutch engineered to prevent gear damage by automatically disengaging gears during a bind-up situation.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eVariable speed trigger enables user to match the speed to the application.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c!-- more --\u003e\n\u003ch5\u003eWhat our Experts Think\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli data-start=\"115\" data-end=\"350\"\u003e\n\u003cp data-start=\"117\" data-end=\"350\"\u003e\u003cstrong data-start=\"117\" data-end=\"148\"\u003eBuilt for Heavy‑Duty Tying:\u003c\/strong\u003e Made with \u003cstrong data-start=\"159\" data-end=\"197\"\u003e16 gauge black annealed steel wire\u003c\/strong\u003e, this tie reel gives \u003cstrong data-start=\"219\" data-end=\"250\"\u003estrong, reliable rebar ties\u003c\/strong\u003e — up to \u003cstrong data-start=\"259\" data-end=\"275\"\u003e65% stronger\u003c\/strong\u003e than typical lighter wire options. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"351\" data-end=\"539\"\u003e\n\u003cp data-start=\"353\" data-end=\"539\"\u003e\u003cstrong data-start=\"353\" data-end=\"375\"\u003eHigh Productivity:\u003c\/strong\u003e Each reel delivers approximately \u003cstrong data-start=\"409\" data-end=\"421\"\u003e245 ties\u003c\/strong\u003e, keeping crews productive on large‑scale rebar jobs without constant reloads. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli data-start=\"540\" data-end=\"747\"\u003e\n\u003cp data-start=\"542\" data-end=\"747\"\u003e\u003cstrong data-start=\"542\" data-end=\"563\"\u003eEasy Load \u0026amp;
