    i just bought an sds max rotary hammer drill and want to purchase the smallest bits that will accomodate 3/4 and 1" poly pipe. will a 3/4" bit work for 3/4" pipe or do i need to go up to a 7/8" bit? will a 1" bit work for 1" poly or do I need a 1-1/8" bit? thanks.

    I think you want to go way up in size, in order to fit PVC pipe, into which the poly will fit inside.

    You are not putting poly in the basement are you?

    Copper or brass would be better.

    If you are going poly make sure you use 200 psi or 250 psi service line quality.

    You should go down to a rental store and compare bit sizes to the size of your pipe

    Both require a minimum hole just larger than the insulation that will be used to protect the pipe.

    Even in the great state of Jefferson 2.5" is the minimum for a penatration.

    IMHO galvanized would be better than PVC or Poly but not as good as brass or copper.

    I think the only time I ran naked poly through a drilled hole was outdoors with railroad ties.

    I did type "poly" - obviously the word was stolen by forces unknown :confused:
