Review on Bosch RH745 4 Inch SDS Max Rotary by Brian Olson

Bought RH 745 to make a few hundred 3/4" and 1" deep 12-15" holes in filled rebar to drill concrete.When the drills don't hit the rebar,the drill is really fast and easy to use.However,if the four tip drills hit the rebar,it will cause shake and the drills often get stuck in the rebar.The device has no reverse function switch.to help extract the bit no derailleur downgraded my rating from 5 stars to 3 c'mon bosch spring for a two dollar derailleur!
