I had a relatively small project: drilling a driveway to secure Shelter Logic's garage. I was really amazed and pleased at how the combination of this hammer drill bit and the Dewalt Rock Carbide SDS Plus hammer bit set drilled very clean, consistent holes in cement. It seemed easier to get a wood drill through cement than wood. I liked how the handle is attached to the front and found the depth gauge very useful. Now I'm looking for the next opportunity to use this wonderful drill. It's well made, versatile and works well. I would recommend it for home projects. I can't say how it behaves in daily professional use. But the price makes it very valuable.
