Through an unexpected turn of events I have recently gone from having
no working circular saw to having two. (One fixed, one "inherited")
One has a 40 tooth 6.5" blade. The other is "coarser", probably 24
teeth, and 7.25".

Plywood is the most likely material for me to be cutting with a
circular saw. I don't have a table saw. I am a weekend home handyman
who occasionally makes a "boxy thing with face frame" type of project,
or maybe just shelves. My skills are modest, but the uninformed
usually find my work quite impressive.

Goodonya, mate.


I see that an 80 tooth "plywood" blade can be had very cheaply, for
under $10. I have also seen much more expensive ones. Due to an
ongoing close relationship with medical care and the bills that
accompany it, an expensive one is not in the running right now.

Will a guy like me gain a noticeable improvement with a cheap 80 or
100 or 140 or (jeez) 200 tooth blade, as compared with the 40 tooth I
have now? If I get too high a "tooth count", might I just as well use
a torch for all the burning I'll do??

With a circular saw, I got a much flakier cut from a new HSS plywood
blade than I did with a nice, fresh, sharp, carbide, cheapie blade
with 1/3 the teeth. I won't use a plywood blade on a piece of hardwood
ply. It's too expensive to screw up.
