Forgot a dryer vent hole... now have a 4" thick veneer of split faced block. Can this drill through that? And if so.. what kind of drill can I use? What else would I need? Normal drill?

Answer: 
You would need an SDS-Plus rotary hammer to use this core bit. It will not work with a standard drill. You would also need the shank with pilot bit that this core bit attaches to. We offer T3922 3" length; T3923SC 4" length; T3925SC 7"; T3926SC 13" and T3927SC 17".

Answer: 
The T3917SC is designed for concrete and masonry. For drilling into granite we would recommend a diamond hole saw like the HDG318, you will also need the HDGQA mandrel and HDGPB6 pilot bit.
