This is an SDS+ But designed for use in SDS applications such as rotary hammers, this is not designed to be used in typical hammer drills. Bosch makes a bit line for regular drills that does wonderfully on concrete.
I don't know. I have drilled about 20+ holes through 12" hard concrete and can still drill a lot more. The wear doesn't seen noticeable.
Yes because you need the hammer action to make this drill bit work best...and it works great in granite!!!
