Sometimes you need a hammer, sometimes you need a drill. This powerful (SPLINE) Hammer Drill can be set for rotation only or rotation with hammering. Its reduced vibration makes it the smoothest operating unit on the market: which means less wear and tear on your arms and wrists. This tool is designed so it won't hammer at idle and the one-touch sliding chuck means easy bit installation and removal. The convenient side grip swivels 360 degrees and adjusts to 8 positions forward and back. You won't wear out our trigger finger thanks to this units comfortable trigger switch. Avoid wobbly starts with the soft start electronic switch feature. An electronic variable speed control dial gives you more control. This durable tool is built to last and includes a depth gauge, bit grease, tool case and for a limited time comes with three "FREE" bits.
