Cheap TCT slitting saw
Hello, this is my first proper post here though I've been lurking for a while.
A few years back I bought a pair of TCT blades for the Ozito plunge saw (24T x 89 mm x 10 mm, about 1/16 kerf) for a project that never happened. Today I though I'd try one as a slitting saw to cut 25 mm deep slits in 8 mm mild steel.
Worked like a charm. I mounted it on my home-made 10mm arbor (18 mm OD) and stuck it in a collet on the old mill/drill. After a little experimentation I found it cut happily at about 250 RPM lubricated with squirts of WD40.
Given the tolerances here and there most of the teeth weren't doing any work, so between slits I loosened the fixing bolt on the arbor and rotated the blade a bit in the hope of evening the wear. (The arbor is home made, 16 mm OD at the business end.)
At about $13 for a pack of two these blades seem like a good value where precise thickness isn't an issue.

Hi, I've been doing a similar thing with those cheap 125 mm TCT saw blade out of Aldi and Lidl ! Very good value. I've found that the blades are quite well centred and don't wobble up and down making the cut wider than it needs to be. I've used mine on both the lathe and mill, but at 450 rpm the drill press is a bit too fast for safe working.
Best Regards:
Baron J.
