Unmatched Versatility and Next-Gen Power: The Bosch 18V Brushless 2-Tool Hammer Drill and Impact Combo Kit

Elevate your jobsite performance with the Bosch GXL18V-251B25-RT 18V 2-Tool Combo Kit, a professional-grade pairing designed for high-torque driving and precision drilling. This kit features the innovative GDX18V-1800C "Freak" Impact Driver, a unique two-in-one tool that combines a 1/4-inch quick-change hex shank for bits with a 1/2-inch square drive for sockets. Delivering up to 1,800 in-lbs of torque, the Freak eliminates the need for socket adapters while providing the power necessary for heavy-duty fastening in metal and wood. Accompanying it is the GSB18V-535C Compact Tough Hammer Drill/Driver, which provides 535 in-lbs of torque and 28,500 BPM for fast masonry drilling. Weighing only 2.7 lbs (tool only), this hammer drill offers an exceptional power-to-weight ratio for all-day comfort during overhead tasks or tight-space maneuvers.

Both tools in this advanced combo kit are equipped with high-efficiency EC Brushless motors and Bluetooth connectivity options for customized performance tracking via the Bosch Toolbox app. Safety is a priority with the integrated KickBack Control on the hammer drill, which uses an acceleration sensor to shut down the motor during sudden tool reactions in bind-up scenarios. The kit is powered by two CORE18V 4.0 Ah batteries, utilizing 21700 cell technology to deliver high-density power with 50% less weight than traditional dual-layer batteries. Combined with the CoolPack 2.0 heat-management system, these batteries provide longer runtimes and a significant increase in tool life. Note: This is a manufacturer-reconditioned tool, certified to look and perform like new.
