I just don't have time to set up my slab saw. I hate wrecking expensive blades, so next time I'll try out some cheapies. The material was too tempting Here's an assortment of dryhead, misty mountain, blue mountain and royal imperial. Scanned wet in a plastic bag.

reverse that blade and and dress it with some obsidian, and if the blade is rounded on the face you`l need to flatten it down with the edge of a no. 2 file use the edge of the file strike the blade just enough to flatten the blade to a right angle, marking the blade, completely striking around the cutting face. about ever 1/8 inch.
this can be done on the saw.

What are you using for cutting oil? Is the rock being pulled into the blade square? there are many problems that can be corrected with a little patience. Properly set up a blade should last for years.

These were cut with my genie trim saw attachment. The coolant is water with lube kool. The rock is hand fed and maybe I am a little impatient. The diamond edge was 80% gone. I'm surprised how fast the blades wear when used for slabbing. I'm going to try some $20 blades I just got. They are thinner than the .032 so I will need to be patient.

Here i thought you were using a 10" Or 12" screw feed slab saw. MK-303 on screw feed well last years, WarrenA is RIGHT, They well out last every blade on the market.
at best the trim saw is for 1/4"-3/8th" not 2"-3" just to post photo`s in a a hurry. So your pushing large material through a 6" blade.
All slab saw blade are to run at minutes to the inch.
no matter the diameter of the blade,
4, 6, 8. minutes are the average speeds on large saws like HP, Fran & tom. i new them personally, Lortone, Nelson, Royals, Hill Q. They all ran very close to 4-6-8, minutes. a few other`s i don`t deal with they are junk saws to me.
Old saying SPEED KILL`S.
The $20.00 Harbor freight blade, Enjoy.

Yeah,Iv'e had my 303 for about 3 years and it has lots of matrix left.It's on a 10 inch screw -fed and I seldom push it by hand unless the material is fairly soft.I use Roc-Oil,a mineral oil.Sintered blades have to be dressed once in awhile by cutting a soft material like the A.O. bars that suppliers have. If you feel the rock getting anywhere past warm,you are cutting too fast!Mike.

If you see sparks you might be losing diamond... use loads of water/surfectant or a good cutting oil. Don't push so hard, listen for that, ting-ting noise... Just trying to help
