I have a cheap circular saw from B&Q with a 20mm spindle and, I think, 160mm blade. I want to get a thin blade for the saw to use to cut access hatches in chipboard floors. Whenever I Google on the subject clearly loads of references to products come up, but they don't mention the width of cut. I did find a "fine" blade on the Axminster site, but wasn't sure if that referred to the pitch or cut width. Perhaps the 2 are related?
I was thinking of setting the saw to 45 degrees and just (!) deeper than the board depth, then cutting a rectangular hatch.
What blade should I ask for and is this idea going to work anyway? :)
