Voltage determines the power and potential torque a cordless hammer drill can deliver. Higher voltage typically means more power for tougher materials and longer runtime, making it a crucial consideration for heavy-duty jobs. Most professional-grade cordless hammer drills, such as the Festool 18V KHC and Festool 18V TPC QUADRIVE, operate at 18V, providing a strong balance of power, weight, and runtime. This voltage is optimal for demanding construction and renovation tasks. With 18V models available, customers can select a tool that offers enough power for a wide range of drilling and hammering applications.
