Got some insert blanks for the new table saw. They are made out of UHMW.
I have a WWII blade and I'm wondering how much running the blade through
this UHMW will it dull the blade.

It's probably the "friendliest" stuff that blade will ever cut.

Don't want to do it if it means the blade will have to be sharpened
sooner. I just got this blade a couple of weeks ago.

The blade will dull slightly with every cut no matter what, but you'll
never notice it with UHMWPE.

Have fun chasing the sawdust. :-)


Just FYI...

"Care should be taken to keep tools sharp because UHMW-PE can rapidly
dull tool cutting edges,..."
