Still fighting termites!


After many hours of trying to drill a couple of holes and going through
many drill bits, I purchased one of the SDS type masonary drills at a
Harbor Freight store for about $50 and the drill bits (special type)
were about $12 for a pack. This setup goes through concrete like a
knife goes through butter. It's not commercial quality but it works.
No more standard masonary bits for me !
