Steel Cutting with Worm Drive Saws

[authority]

I had a new Ridgid R3210 and decided to try a Freud Diablo D0648F 6-1/2" x 48-Tooth Steel Demon TCG Ferrous Cutting Circular Saw Blade 5/8" Arbor.

Reasoning behind the 6.5" was the tooth speed would be slower than a 7.25" blade, and I didn't need any of the extra capacity.



You can't even tell it's cutting anything on the light gauge (1/8") 3x4 tubing I tested it on, the chips are small and the cut is cold.

Other note is that this is a painted tube, and if you were completing a repair, there is not any heating or discoloration of the finish.

pretty neat. I'm wondering what the cut would be like on a thicker piece such as 3/8"?

According to the printing on the blades, they don't recommend thicker than 1/8" or bigger diameters (tubing) than 1" -

I'd be interested to know what kind of blade life you're seeing, if you've used it very much... Steve

These blades work pretty good, I've gotten good results using a cheap skil saw.

But they do tend to rain down hot chips as they cut that then get everywhere. I picked up a Milwaukee metal cutting circular saw to build a maple syrup evaporator for my brother. It still makes a mess with the chips but is somewhat more covered in the blade area in that I didn't get the chips sprayed all over me anymore. For 300 bucks or so it was a pretty good buy, with a guide bar the fit-up on the 2x7x3 evaporator was practically perfect, very easy to tig everything together.

I've used various steel cutting blades in wormdrive saws and had lots of hot chips everywhere. For a while now I have used the Makita saw below which generates chips that are almost cold, and most of them stay in the guard. It cuts 1/2" mild steel with no issues. The battery lasts long enough that it is not a constraint, when it does run low just switch in the second battery. A speed square clamped to the work will give a perfect cut every time.

OK I have to ask that blade in the picture looks like it is mounted backwards. Does that saw run clockwise ?

Zoom in. You can then see that the teeth are opposite of where they look like they would be in the smaller picture, and the rotation/blade are all normal

Here is a closeup of blade. lots of negative hook and a controlled feed design. rotation is normal.

Thanks for taking the time to send the closeup
