    Went to drill and tap some new holes for the set screws in my conventional. up and down went well and iv got a nice snug fit there.

    but the angle valve housing is made of some effing strong freakin steel.... did they make that thing out of stainless? #36 drill bit, maybe not the best, whatever came with the tap. but i could barley get it to even dent the thing. no way would it have drilled through. and tapping it might be near impossible.

    anyone know for sure?

    You probably work hardened the steel buy using a dull drill and no cutting oil, or you're drill motor is spinning in reverse.......

    I could torch it red hot and let it cool slowly to anneal it. but if its stainless im not sure that would make a difference. there is no rust, so im thinking its stainless

    Carbon steel or Stainless a HSS drill should work up to about 38rc.
    Don't torch it, you'll blow next months bill money on parts.

    i figured as much. seeing how hard it is. gonna be hard finding a high speed steel bit in #36

    thankfully, iv never had trouble with this one moving around.

    HSS drills are the most popular drill manufactured in number, letter, fractional and metric sizes.

    Go to a Fastenal.
    Cost from expensive to cheaper.
    I assume you using the #36 drill (.1065" dia) for a 6-32 screw, if so just use a 7/64th drill (.1094" dia). It's only .0015" less thread engagement and it won't a difference.

    Use a magnet to check if it is STAINLESS... If it sticks, it isn't, or not very good.
    "In general, there are three kinds of metal-drilling bits, basic high-speed steel, then titanium-coated, then cobalt alloy. Only the last is rated up front for SS or cast iron, and is also the most costly, but you pretty much get what you pay for. "

    Some grades of SS are magnetic.

    Even being cast it should drill with a HSS drill as long as RPM's are low, cutting oil is used and drill is rotating in the correct direction.....

    It is magnetic. and there is no way the bit i had is going to get through. im just going to have to buy the strongest kind of bit i can buy. once i figure out what it is.
