Specific hole saw for frame sliders?
 

What specific saw do people use when cutting the hole
For the frame sliders?
I'm trying to find one that won't rip it apart and make as clean of a cut as possible.

just use a fresh saw, cover the area with masking tape before you cut, and take it slow. the smaller the saw teeth, the better.

Drill a pilot hole, then dremel.

I used the circle cutting tool it worked awesome

A company called Greenlee makes a specail hole saws for fiberglass.

hell no on the dremel idea thatll come out uneven. regen nailed it. tape it up and use a saw with the smallest teeth you can get and youll get a nice clean cut. A pilot hole will help out a lot if youve got a holesaw piece with a drill bit in the middle otherwise dont bother. But itll definately be easier

Link?

the trick to using a hole saw in any thin material is to back it up with a block of wood or something. Otherwise, the pilot bit won't have anything to guide it as it makes the last of the cut and it will wobble.
