    Default Help With Drilling 1&1/2" Holes in PVC???


    I am trying to find out what type of bit I need to drill 1&1/2" holes in 4" PVC. I bought a wood boring spade bit locked it up in an 18 volt drill and dang near broke my arm when it contacted fully with the PVC!
    I don't know how to contact "chef" at J & H Habitat to ask him what he uses. He hasn't been on-line in quite a while. If anybody knows how to contact him or has a good idea what type of bit I need please let me know.

    Default Hole saw

    Visit your local Home Depot or Lowes and purchase a bimetal hole saw. The outfit will have a arbor with a 5/16" drill bit in the center and acts as a guide for the actual hole saw. The hole saw's are available in a variety of sizes that thread on the arbor. I recommended the bimetal just in case you would use it in mild steel or aluminum in the future. Hope this helps.

    Default What he said

    Also check at a pawn shop, might come up a little cheaper. A drill press is nice too but the hole saw will do the job, just watch your speed to prevent a broken wrist. Ferdi aka fred

    When I made some rod holders out of PVC. I use the hole saws Rollcaster mentioned. They come in all sizes. http://www.lowes.com/lowes/lkn?actio...16A&lpage=none

    Thanks for the tip Rollcaster but the thing that I don't like about hole saws is that you have to stop and remove the PVC plug after cutting every hole. They do cut very smoothly though and if I could find out how to keep the hole saw from getting plugged up I might would try them again.

    find a contractor that has concrete bits that are too dull to drill concrete
    1" and 1 1/2" will still work for pvc
    if they are "sds" style you can cut the shank off and use like a regular bit

    I do agree it is a inconvenience of the holesaw after the hole is made. I always look for the ones that have slots in the sides so you can access them with a small screwdriver to punch/push the plugged material out. I personally don't mind this if it keeps me from having to clean up all of the shavings of the other type bits that are available. My wife also likes them to, since I'm not tracking in the pvc shavings from the garage. They only thing else I could recommend is a electric drill to replace your cordless. The electric would have more rpms and torque that may keep the paddle bit from biting in too hard when starting the hole. Hope this helps. Rollcaster...................

    I did notice the cleanout groves in the bits that you mentioned. The one that I tried last year did not have these and I had to use a small screwdriver to pry the plug out. I like the idea of less mess and I think I will try your suggestion.
    Thanks

    I use the wood boring spade bit and just angle it to one side then the other. A higher speed electric drill will also help. And let it cut slowly....not forcing it through.
