I mentioned the other day on a thin parting tool post that I had bought an el cheapo priced (not normally) Rage technology saw blade. 71/4" diameter by 1/16" thick.
Now this is where I try it out for the reason I bought it.
Sometimes, you really do need to get something to reach a fair way, and usually, the vice gets in the way. Using this, even with a slitting saw holder nut underneath, I should be able to get a reach of at least 3".
There is no side to side offset on the teeth at all, and the cutting edge is perfectly square across, and by the looks of them, there is very little, if any side clearance, basically, just like a normal slitting saw, only much larger. At this sort of size and thickness, I expect it to veer off slightly on the cut.
So it was mounted up onto my universal arbor, the hole wasn't quite the right size, but it will do for this trial. If it works out OK, I will resize the hole and put a drive dog slot in it, just so that it gives an even cut.
For a saw not quite as large as this, I would normally run it around 100RPM, but because it was a rage blade, and is designed to run a lot faster than my mill can go, I decided to play safe and run it at just over 400.
Power feed on, a bit of WD40 as lube, and the blade went thru the ali as though it wasn't there.
No deflection at all, which really surprised me. Just a nice, very clean cut thru almost 3" (actually 69mm) length.
Job done, and the arsenal gets a new tool.
I will try it out on steel next time the need arises.
