Edward, in my opinion using a Centrotec bit for masonry work would yield you nights...other than of course the naked, new bit, is a pretty nice looking piece of equipment...
Drilling concrete is a pretty crude task & any extra precision gained by using Centrotec bits would surely be lost in trying to keep a SDS bit with a blunt carbide tip in one particular location. As soon as the hammering and rotation action starts to happen, the point of the drill has skated across the concrete surface and you're now drilling an oblong hole.
Locational tolerances with concrete, will probably be +/- .030" min. if you're lucky, realistically more like +/- .060" or greater if you are not careful.
