Tackle tough jobs with the 6445-02 120-volt 1/2-Inch hammer drill from Skil Power Tools. The drill sports a powerful 7-Amp motor and a 1/2-Inch keyed chuck for the most common bit shank sizes. A switch lets you set the tool to operate as a traditional drill or a hammer drill with a hammering action. A detachable side-assist handle offers greater control, as does the two-finger, variable-speed precision trigger.
