Planning to install my first tile floor soon and I’ll probably be using Hardiboard or similar product under the tile. I used a 5″ hole saw to cut the toilet waste through the subflooring. I’d like to trace the outline of the hole onto the cement board from underneath and repeat the cut with the same hole saw to keep things neat. Will the same hole saw handle that or will I need a jig saw and special blade?
Thanks for any assistance.

you can use the hole saw but it will dull the heck out of it,and 5" hole saws aren't cheap,i would just grab the sabre saw and a couple blades and cut it,you might waste 2.00 worth of blades but oh well,better than a 40.00 hole saw. it will cut pretty good with about a 8-10 tooth blade. larry
why pay someone to screw it up,i can do it for free....
Hardi is sort of like an abrasive stone, I would not waste my holesaw, but a grit edge (or diamond edge )holesaw would be OK.
Bosch makes a sabersaw blade for cement board or tile. Tungsten carbide I think. I have cut at least 100 lf of hardiboard with the same blade,it's dtill in good shape.

Yes it will... once, maybe twice. I ruined my 4 1/8 hole saw on some hardy running a pair of lights.
Make a series of thin pie slices with an angle grinder, then snap them out.

I make that cut with a 4'' grinder and tile blade.
Cut an octagon around the outside diameter. The tile will cover it up.
I believe in being neat but in this case it will only cost you time and money.
Once the tile is down no-one but you will know that it was'nt a perfect circle.

Dont cut Hardi with anything you ever want to use again.
I use a paint stick that I have multiple holes drilled in for different sized holes, then cut the hole with a sawsall.
Take a look at Ditra which is the flooring product made by the company (Schluter) which makes the Kerdi that you hear about here a lot. The ditra comes in rolls, its about 1/8" thick cuts with razor and is about the same cost as hardie, and others. Check out the link and do a search here and on johnbridge.com. The product in combination with the kerdi for the seams can make the floor completely waterproof.

Use a rotozip with a tile bit. It works great. Don't try to cut the floor tile with this bit. It will work on wall tile though.
4" diamond blade on an angle grinder. Very dusty; very fast.

Just run the HS in reverse, it'll lose a little of the set of the teeth, but easily touched up with a thin disc in a grinder.
