Using a rotary hammer to blast through rock and concrete can be a time-consuming， laborious chore， unless you've got the right bit. The DEWALT Solid-Head SDS+ is the right bit. It's equipped with thick Solid Rock Carbide tips， which contains twice the carbide found on competing bits. And thanks to its four-flute design， this bit rapidly removes dust and drills holes with lightning speed.
