a friends 16" saw blade leaves an 800 to 1600 grit polished look, he isn't sure of the blade other then its an old MK series.
Anyone else know of a blade that does this?

My 14 inch MK301 doesn't leave any saw marks. The 16 inch old Covington blade did and some slabs I buy have them.

My Raytech 10" trim/slab saw with a cheap Chinese blade leaves a very smooth surface, no saw marks show.
It may be related to the feed speed.

Old Sears (Star Diamond) 10" with Hot Dog blade leaves a nice shine on anything other than really soft material. HP 10" with a 303 does the same. Both are gravity feed with a relatively slow feed rate. zarguy probably nailed it there.
Antique 10" with Hot Dog does not "polish" same types of rough - it's used for hand feeding inconveniently shaped rough using a fence. Lot faster feed rate.
18" 301 (different blade design) yields nice smooth slabs, but not a "polished" look at 18"/hr feed rate.

Yeah I know a slower feed rate should help it, I kind of wonder if a glass blade will be better with continuous rim since the grit is finer? |
