Rockwell H3 Rotary Hammer Drill

By Robert Robillard on Tool News


The Rockwell® H3 Rotary Hammer Drill is ideal for anyone who has the need to drill a few holes in even the toughest concrete but doesn’t want to lug around a 20-plus-pound rotary hammer drill.


Ultra-compact, lightweight, powerful and Euro-styled, the H3 rotary hammer drill is one of the latest tools in Rockwell’s extended family of 12-volt lithium-ion power tools, which includes a 3-in-1 3RILL, drill/driver, screwdriver, impact driver and Sonicrafter®.

This 3-Function Rotary Hammer Drill is a real time saver when it comes to drilling in concrete or brick. It makes jobs like installing concrete screws, gutter brackets, mail boxes and conduit clamps a snap.

The H3’s unique 3-in-1 quick change chuck system gives the user flexibility to immediately switch between using the tool as a rotary hammer drill, conventional three-jaw drill or power screwdriver. Insert the traditional three-jaw chuck into the tool’s collet, and it converts from hammer drill to conventional drill. Insert the SDS Plus bit-holder, and the H3 is now a powerful screwdriver. A dial switch on the body of the tool lets the operator switch from hammer to drilling mode.
