I use half of a basketball with an arbor cutout for a hole saw for remodel cans. You should see the looks I get :blink:
You guys who use hole saws, how do you get them lined up perfect with the cans? Or do you just make the holes a little big or fidget the cans around a little after drilling? I usually use the "start the rotozip in the waste so you can find your edge without screwing anything up" method like gbruzze and ronnie said.
JR Shepstone said:I don't think the guards are necessary. Set the bit, and forget it. Mark approximate center of the can, go until you feel resistance, pull back a little and it should slip over the edge. From there, cut in a counter-clockwise (or is it clockwise?) direction following the edge. Bing bam boom it's out. It's an applied science mixed with some feels. I'm not great at it, but I don't let that stop me from trying. It's only a sheet of drywall.

Hole saws are fine if you don't have customers who will get on a ladder and measure and sight to see if everything's exactly in place.
the way I do it is.....I don't use a guard at all...(lost it a long time ago)...plunge into the middle of the cut out....cut straight towards the stud side of the box...( can lights it doesn't much matter) . . feel the edge .. jump to the outside of the box....cut going counter clockwise...the bit turns so it pulls towards the box that way. a little practice and you'll get the feel for it
I don't get this - I can locate holes in drywall more accurately than the sparkies usually locate the cans. You'd have to be some sloppy with a hole saw to get as bad a can location as sparky / rotozip will get you.
