Our SDS drill bits do have the grooves in them, but Hilti drills take 3 types of grooves. The bits we carry will fit in the Hilti SDS plus drills. The bits we carry are SDS plus bits and the connection shaft is about the width of a pinky finger with the grooves. Some Hilti drills take a bit that has what is called SDS MAX bits, where the shaft and grooves that go into the drill is larger than your thumb. Then there is a middle of the road one. So yes it has grooves, but it is the smaller SDS PLUS bit. To be sure, you may want to call Hilti USA and give them the model number of the drill you have and they can probably tell you which bit it takes, or if our SDS PLUS bit will fit it.
