Drill stuff and hoses, My man Mike! (wink wink, nudge nudge 😃)
Never can have enough specialize bits. I have a wide variety of diamond bits for mostly my wife's glass stuff, but since I am their keeper, I get to use them when ever.
Hole saw/bits are a gripe of mine. They always get fried (mostly from my abuse). I'll need to start buying the carbide tipped units in the future.
