Upgrade Table saw with Multi Purpose Blade?

[sambat]

I was considering replacing the wood blade on my table saw with an Evolution RAGE Multi-Purpose Carbide-Tipped Blade, 255 mm, which will allow me to also cut metal and plastics.

However my table runs at 4500rpm, and I believe the Evolution blades run slower.

Can you see this being an issue?

yes dont even think about it

Yes, absolutely an issue. Over running any blade beyond its rating is asking for trouble. Not only will it not perform as it would on its dedicated saw, it could well be as it's simply not manufactured to run that fast and worst case scenario bits could fly off or break up. Absolutely this is commonly the case with abrasives and not solid steel discs but never the less, it's not a risk I would take.

Example. I have a Makita LC1230 TCT metal cut off saw and it runs very slowly compared to the abrasive cut off saw they do. I once saw a guy who, rather than buy a dedicated saw, as you simply put the Makita TCT blade on his abrasive saw. It didn't last five minutes, caused a right row as it went dull and lost teeth, probably half knackered the motor and did no better job on the work than the abrasive discs.

Just to add, the rage blades are to be run at a max of 2500rpm. Asking for trouble.
