I use them for my siesmic work in California. I have used them for setting anchors in rock and they tend to skate a little more than the standard sds bit, also if you are hand placing "hand drilling" the flutes on the hilti X heads tend to bind more and it will take more forearm strength to turn the drill. As for the price they are worth it for rebar/concrfete but for setting routes in rock I would stick with the standard bosch/hilti's they are around 6-7 bucks each and depending on the hardness of the rock/medium I have drilled around 20-30 holes per unit before the drill bits dull. Hope this helps Anthony Experiance has shown that the standard bosch bits are not the way to go. Out of the couple dozen Bosch bit's I have owned over the past 5+ years I have yet to get more than 10 holes out of any of them. The average being about six. Some were less than one hole. This is with both hand drilling and power drilling in dredominantly limesone, however a couple bits were used in quartzite, granite, and basaltic rocks. As for the Hilti's... I've only ever purchased one. In fact it was the first bit I purchased, and I'm still using it. I think I paid around $30 for it. I've hammered in somewhere around 50+ holes with it, and although it is not as sharp as day one it still drills a perfect hole, and still hand drills faster than a brandnew Bosch bit. I've put holes in Limestone, granite, quartzite, sandstone, and basaltic rock with that bit. I may retire it after next summer, but then again I said that last summer and the bit is still just fine. As for skating around more with the "X" profile. I have never found this to be the case.
