I have never used a cordless hammerdrill other than a Milwaukee. I'm not real impressed with the Mil hammer so Dewault's version could very well be much better for all I know. As far as top speed is concerned, I have never felt the need for the chuck of a multispeed, cordless drill to turn faster. It is already too easy to strip-out, slip off, or burn up screws, holesaws, etc. What type of operation would you wish-for/require greater speed? Having three speeds instead of two on a cordless drill seems gimmicky to me.
