Since 1923, Ridge Tool Company has been producing RIGID brand tools with professionals in mind. Their heavy duty hand and power tools, like this 18-Volt Lithium-Ion Cordless Drill, are built to endure the rigors of daily use, which means they keep performing, job after job. In fact, Ridge is so confident in their tools' knock-out performance that they even offer free replacement batteries and free service for life. In the unlikely event that a RIGID tool does malfunction, they'll replace it free of charge. Available at The Home Depot; $119.00.
