Your Favorite 12" Miter Saw Blade

[Cooler]

I used to own a picture framing shop.  We used (I still have it) a Frame Square sliding table miter saw.


I used a 12" 100 tooth negative hook angle blade for the cleanest cuts.  You have to use a slower feed with these blades but the cuts are mirror smooth.

I heard that Frame Square is out of business.  Hoffman sells similar blades:

If you want perfect miters without any compromise, then a miter trimmer used after the miter cut will do the very best job.  I have a Lion Miter Trimmer.  They were knocked off so much that they've gone out of business.  The trimmer is not much compromised by the Chinese production but the blades don't hold the edge nearly as long.

The little brass cams on the stop allow precise adjustment.  The blade will slice so thin that you can write on one side of the thin trim and read it through the other side.  Probably as thin as .002" or .004" thick--about as thick--about as thick as a sheet of copy paper.

Thank you Cooler!!!!!

The miter trimmer blades can be re-sharpened.  A freshly sharpened blade can be as dangerous to handle as a razor.  I always kept one set of blades in the trimmer and a second set freshly sharpened on the shelf. 

You cannot cut a miter with these trimmers.  You can only trim after cutting.

This You Tube video shows a Morso miter guillotine cutter.  It is slower than an double miter saw but it is almost completely silent and generates no sawdust.  These can be vital distinctions for a mall-based frame shop.  Eliminating dust is a major advantage for framers as it means less work making sure that there is no dust inside the assembled frame.

They are built in Denmark to a very high standard.  A premium miter machine.
