Ant some of the Dake saws run at 350 RPM. Big difference.Originally posted by eKretz View PostYeah, those budget chop saw dealios are not very good for challenging stuff. There is a world of difference between one of those and one of the big boy cold saws. About like the difference between a crappy Chinese lathe and a Monarch or similar. Totally different class of machine. Not only is the speed way too high, they are not anywhere near as rigid as the good cold saws. Rigidity is important for blade life. Many of those better cold saws have power feed also - another big help to tool/blade life.

And a Fein "cold-cut" saw is not a true cold saw - or at least not a very good one. They run at way too high an RPM.

I love both!! JR
P.S. > I meant a solid 14" HSS with no carbide tips.
Just wanted to make sure.
HSS slitting saws and slotting saws are always HSS. It is fracture norm if you bind it up.
Imparting a 90 degree fours' from the arbor, duh
With a nice slow saw it wont ask if the blade fractured. 14" blade. too much. so dont do it. Money.
Firm base and go at it with the HSS blade. It does not like to side load. It needs a good down force and steady feed.. JR

If the blade was not carbide tipped then he was doing it wrong.

I have no idea why anyone would use a HSS blade, except that's what the saw comes with just to get you started.
The blade was taken to Forrest which makes, re-tooths and resharpens circular blades of all types. They asked about the machine it was on and material typically cut, didn't recommend a change and said it would be ready next day.
