Do you think around 28,000 rpm is to fast to run a jewlers saw? Without looking I think the blade is 2.5 dia .040 thick

I don't see a need to go over 12K.
I spin the chuck at the slowest and cut rings real slowly with my face way way away from the saw blade.

It better not be - many of us have run them on lam trimmers
for years.
I would strongly sug. you build some type of 'blade guard'.

If you use it much, at some point. the blade will come apart.

Thanks for the information. I was pretty sure what you were talking about. I have a mount for my dremel and the same type of saw blade and arbor for it. I've had exceptional results.

Are you using a router speed control?

I'll build a guard for it as well.

I'm guessing that it's HSS. Yeah, that's waaay too fast. If it's the blade that I'm thinking of, it's max. rated at 13k. A concern that you should have at that speed (28k) is blade flex/wobble. Instant self-destruct & watch for the shrapnel AND the ricochet. Solid carbide would be a better choice. You could stand a smaller diameter as well. Think about it, what's the wall thickness of the billet(s) you're cutting ? Let me send you a PM.

My Makita is variable speed.
Ridgid also makes a cheap one available at Home Depot.
Or you can just use a rheostat.

Whatever speed you decide to use, make sure the blades match the saw rating. As noted previously, over time they may come apart.
