The teeth feel much catchier after filing them with a triangular jeweler’s saw (left half is done), but it still takes a minute of rocking the but back and forth to get through 3/4" plywood.
If you drill a few 1/4" holes where the holesaw lands it will clear sawdust and cut 2x faster.
Start holesaw hole, drill dust holes, finnish holesaw hole.
Going to need an illustration so I don’t get my dick stuck anywhere…
Start drill. Your dick will no longer be stuck anywhere. Rather, your dick will be everywhere. Problem solved.

Starett make some of the best ones as far as I’m aware. That’s what I use. Can’t fault them
I’d splurge for a hole saw with carbide teeth. Costs more but lasts longer
Buy a new one, or better yet a set of forstner bits. Holesaws suck in comparison when it comes to quality. Takes a bit longer to cut large holes tho.
Yeah, very happy with my Forstners which I have up to 1-1/4" I think.
I wonder if the steel in the saw got hot enough to lose its heat treat. If not, sharpening is a great idea. If yes, you will still be able to get the blade sharp but it won’t hold an edge as long as it did originally.
This all really comes down whether or not you saw smoke from the wood, the species of wood (some smoke much cooler than others), and the alloy (some alloys have much lower temp heat treat processes than others).
This one definitely has made some smoke.
