DeWalt DCK226E2 20V MAX 2-Tool Combo Kit vs DeWalt DCK299M2 Hammer Drill and Impact Driver Kit

The DCK226E2 is the lighter, more compact kit: a 6.49-inch hammer drill and a 1,700 in-lb impact driver on two small POWERSTACK batteries. The DCK299M2 is the heavier-duty XR kit: a 3-speed all-metal-transmission hammer drill, 1,825 in-lbs of torque and two 4.0Ah packs that run much longer per charge. Buy the ATOMIC kit for tight spaces and light-to-medium jobs, and the XR kit for sustained drilling, masonry and all-day professional use. Owners of both rate the tools well; the XR kit is the one most pros keep as their primary set.

• Choose the DCK226E2 if you work in tight spaces, want a compact kit that is easy to carry, and mostly drill and drive in wood, metal and light masonry.
• Choose the DCK299M2 if you drill masonry and bore large holes regularly and want the longer runtime and extra torque of 4.0Ah batteries and a 3-speed drill.
