For the most demanding applications, secondary cordless tools, such as rotary hammers, are still underpowered,We understand the importance of staying within the preferred 18V platform and offer a rotary hammer powered by two 18V lithium-ion batteries for 36V power and run time. This is ideal for applications that take users away from a power source.
A hammer drill has a higher RPM, or speed, than a rotary hammer, and does not hit as hard,The percussion or hammering motion is created by one hammer plate spinning against another and requires the user to apply pressure to the tool. These tools are typically used for drilling smaller holes and in softer aggregates, such as cinder block. Rotary hammers have a slower RPM but hit much harder. The greater impact energy allows them to drill larger holes, into harder aggregate, and is much easier on the user.
