I need a blade with square teeth for box joints-like cuts. That is, flat
ground top and sides of the blade that are 90 degrees from the top. I
thought I had gotten one from Freud, the LM72M -- the picture shows it
being square, http://www.freud-tools.com/freudtefinhe.html . When I started
making some cuts I noticed that it is not square.
Freud-tools.com, where I bought it, said they thought "it might have been
changed in the Spring". A call to the factory confirmed that they no
longer make a real square tooth. Nobody would own-up to the picture being
So now I am looking at maybe the WWII "customized" with the #1 grind --
http://forrest.woodmall.com/cuswoodii.html . I have a call into Forrest.
It is a shame about the Freud because otherwise it cuts well -- I am
cutting polyethylene at the moment. I don't need a very smooth finish, but
if Forrest is the only way to go, so be it. And, I am afraid that the
Forrest may have too many teeth -- with polyethylene, it seems that
somewhere around 24 teeth is a good balance between cutting smooth and not
generating too much heat.
It is my understanding that rip blades traditionally were square ground.
If that is so, it seems that science has moved on because I have been
unable to find anyone but Forrest making a square tooth.
So, any ideas where I can find a square-toothed blade? Anyone used the
Forrest #1? Thanks. -- Igor
