Boring holes

in THE MAIN WALL
Looking at some of the pictures in recent post, I realize one of the thing we all share is the time spent figuring how and then boring holes for the vents.

Earlier this year I tried a dry core bit system from Dynacore and after using a large grinder to drive it, I bought an adapter for a Philips chuck and now use a Milwaulkee Super Hawg to drive it. I have been extremely pleased with the results. Very fast , a little dusty and it doesn't blow the back of the wall out.

What do you guys use?

    dry core bits

    I've got a few of them, but the one that gets the most use by far is my 2-1/2" Relton Hammer Core, along with the matching Interrupted-cut holesaw (for rebar.)  They cost more than the Bosch, DeWalt, etc. labeled ones do, but Relton re-profiles and re-tips them at very attractive prices.

    Wet and dry core drill,

    Got this on line about 6 yrs ago, it was a reman no name risk LOL, but it has worked flawlessly. 3x16 wet core, will drill a hole thru a 8"concrete wall in 5 mins or less, it take me longer to set up than drill the hole. best part is i am not the opposing force on a hammer drill ;-)

    Coring

    We use a Hilton wet core. Really portable. Weighs about 20 lbs. mount to wall and core up to 6 inch holes fast and no blow out. Great investment.
