The M18 FUEL™ 1-3/4” SDS Max Rotary Hammer w/ ONE KEY™ generates the power of a 15A Corded Rotary Hammer. It has a 1-3/4" capacity, 8.1 ft-lbs of impact energy, 380 RPM, and 2,900 BPM. Our cordless rotary hammer is designed for the professional user, allowing ultimate power, control, safety, and productivity. The POWERSTATE™ Brushless Motor gives you 8.1 ft-lbs of impact energy that meets and rivals that of corded competition. REDLINK PLUS™ intelligence tool technology ensures maximum rotary drill performance and protects it from overload, overheating, and over discharge. Our M18 REDLITHIUM™ High Output HD12.0 battery delivers unmatched run-time in all applications when used with the rotary hammer drill. It allows the SDS Max hammer drill to chip 1/2 ton of material per charge so you can work harder for longer. Our full feature hammer delivers maximum control and enhanced safety with the AUTOSTOP™ E-Clutch. This prevents over-rotation in case the tool gets bound up while you are drilling in rebar or hard aggregate. Competitive tools can rotate up to 360 degrees while our rotary hammer will stop rotating at 45 degrees when the tool gets bound up. This feature is designed to ensure you work safer and have more control while on the job. The cordless rotary hammer is compatible with ONE KEY™, wirelessly connecting to your smartphone to track and manage the tool’s performance and location. ONE-KEY™ integrated tool tracking gives you full visibility over how and where your tools are being used across your network of jobs and users. The technology is built into the tool and not the battery, allowing you to track it even if the battery is not charged or connected. The app will track all compatible devices within a 100 ft range of your phone, allowing you to pinpoint missing tools quicker and increase accountability of your crew. Integrated Tool Security provides the ultimate theft protection with features like tool lock-out, or the ability to hide power tools from nearby device screens allow you to protect your investments. If your tool is lost or stolen, you can render it inoperable by sending a remote command to the tool to shut itself off the next time it comes within range of any ONE-KEY™ app.
