36V MultiVolt™ Brushless Cordless 1-9/16" SDS Max Rotary Hammer (Tool Body Only)

The 36V MultiVolt™ Brushless Cordless 1-9/16" SDS Max Rotary Hammer (Tool Body Only) is a heavy-duty demolition and drilling solution designed for professional concrete contractors, construction crews, electricians, plumbers, and industrial maintenance teams. Built for demanding applications, the DH3640DAQ2M combines exceptional drilling power with advanced safety and vibration reduction technologies to deliver outstanding performance in concrete, masonry, and reinforced materials. Its cordless design eliminates the need for extension cords while providing the flexibility required on busy commercial and industrial job sites.

Powered by a 36V brushless motor, the DH3640DAQ2M delivers up to 8.6 ft-lbs of impact energy, making it ideal for drilling large anchor holes, installing core bits, and heavy-duty concrete applications. The tool features four selectable speed modes and **two operating modes—Hammer Drilling and Drilling—**allowing users to optimize performance for a wide variety of tasks. Operating at 250–500 RPM and 1,400–2,800 BPM, it provides powerful, consistent drilling performance with capacities of up to 1-9/16" using SDS Max drill bits and 4-1/8" with core bits. Advanced User Vibration Protection (UVP) incorporates a redesigned dynamic vibration absorber and low-vibration handle, reducing vibration by approximately 17% compared to the previous model for greater operator comfort during prolonged use. For enhanced jobsite safety, Reactive Force Control (RFC) automatically cuts motor power if the bit binds, while the integrated mechanical slip clutch provides an additional layer of protection.

This Tool Body Only version is ideal for professionals who already own compatible 36V MultiVolt™ batteries and chargers. As part of the expanding MultiVolt™ System, the DH3640DAQ2M is also compatible with the optional ET36A AC Adapter, allowing users to switch between cordless mobility and continuous corded operation for unlimited runtime. Featuring an integrated LED work light, durable brushless motor, and weighing 14.1 lbs (tool only), this rotary hammer delivers professional-grade power, durability, and reliability for the toughest drilling applications.
