Description of Bosch HC2302 Tapcon SDS Plus 6.5-Inch Drill Bit
For use with masonry fastening systems/hex sleeve drive tools. 20 percent faster. Hex drive on bit fits into driver sleeve. For setting screws in concrete applications 3.5 In. re-useable length.
I don't know what's wrong with my particular product, the head looked a little dull but it was definitely new. I had a lot of trouble getting this drill through a regular red brick, luckily I only had to drill four holes, it was the last one used.
Pros
For installing screws in 3.5" concrete structures. Reuse length
I bought two of these bits to install 3/16" Tapcon fasteners that I use frequently Walls bits used for mounting electrical boxes to concrete have a hex shank that fits onto a Tapcon tool hub, making installation quicker with just one tool rather than changing SDS bits or using a separate 1/4" impact driver to drive in carried along by fasteners. after the holes have been drilled.
