    Hole Saw Size

    What size hole saws do I need for 1" and 3/4" PVC connectors. The info that I have is for ridged, EMT and other conduits. Nothing on PVC. Since the connectors take the same locknut, I assume the ridged or EMT would be the same. BUT, they are not. (as far as the table say's) Just don't get it.

    RMC and EMT have different OD's, but the connector hole saw sizes are the same. 7/8 for 1/2, 1-1/16 for 3/4... I forget the rest. Get an "electrician's hole saw kit" and forget about it.

    1/2 = 7/8
    3/4 = 1 1/8
    1 = 1 3/8

    Notice a pattern?
    The hole size is 3/8 larger than the conduit size

    We use these hole cutters in 7/8", 1 1/16" and 1 5/16". Above that we use the 7/8" with the KO set.

    Me too! Hole saws can get a bit too large.

    I had not seen those before. Nice looking. But I still like this for thinner steel

    Mark,
    You still have to drill to use the KO set. It is faster for the smaller holes to just use the holecutter and be done with it. (at least in my experience)

    Right. There are times, however, due to equipment that may already be in the cabinet, that the extra chips from hole sawing are not tolerable. There will always be a place for slug busters and hole saws. My wrist won't take too much hole sawing action, but that's just me.
