Review on 💎 Diamond-Coated 4 3 X60MM Hole Saw by John Rocha

I was trying to cut holes in the ceiling with 3/4" pine tongue and groove to install LED lights. The teeth are designed to grip wood so the saw is constantly gripping instead of cutting. It is very easy to get injured and sprain or break your wrist. Be careful. This can work well on drywall. I used it to score the surface of the wood and then used it as an outline and cut out the handles with a jigsaw. A fairly expensive option compared to a pencil.
