So I guess the blade was a little more worn than I thought and today it refused to cut a small egg, and an agate. So I am now in the market for a new blade. Trim saw with vise for small rough, I usually just hold it in my hand to cut. I need to be able to cut small rough like Lakers & Montana agates as well as slabs and maybe the occasional small T.Egg.
Must be good for water cooled as I am using RV Antifreeze 50/50 mix and after that I am not sure. Thicker blade - stronger blade, straighter cuts/thinner blade, less waste, slower cuts.
I was looking at the rock shed and these are whats available;
BARRANCA DIAMOND BLADES: dia. thick BD 303 Professional Continuous Rim 8" .025 8" .032 8" .060 BD 303P Professional Wet Cutting Granite 8" .067 & Porcelain Tile (since this is a wet cutting saw for porcelain tile I would figure it would have to be water too... wouldn't use oil to cut porcelain tile!)
so there you are.. .if you have other places chime in and include a website please... no oil blades, must be able to use water on this one!!
And NO... this is not a saw discussion!! I am using a Lortone TS-8 Trim Saw.

It is too bad there is not a .040" - I think .060" is on the thick side. I only use .050" on my 10"
I think .032 is OK if you can develop a light touch. If you are not going to be cutting super heavy costly material, and want to have extra insurance with "hand-fed", the .060" will do the trick. In 10" blades there is a big price difference based on thickness. Not so much in the 8"
BTW, John at JSGems has the 8"x032 for $50 while RockShed is over $60.

Thanx Snuffy, Daniel... I'll see what John has available... and it'll give me an excuse to bookmark his site which I always forget to do with most of the sites on here!!
I think .060 is what I have on my 18.. it does a 1/16 thick cut line.

I have an .025 x 8" SS trim saw blade that I got from Kingsley last year. Continous rim and it works very well for preforming cabs in the 1/4" range. As long as you don't get to impatient, they will do the job. I have warped them in the past from to much pressure pushing. I'm in the need of another 8" blade and going to get it from John this time. Ahh alas, our hobbie is an exercise in patience isn't it? I'm in the need for another 8" blade and going to get it from John this time

I assume that from your Laker post that you are slabbing with that 8" blade (?). If n that be the case, as long as waste is not an issue, Go with the .40 .

With my 10" saw, I've used 303C in .040 and .050. The .050 takes a little more pushing force by hand because of the extra thickness but takes much more abuse, less chance of dishing. I'm rough on blades. You'd really have to screw up to dish a .050. Use the 303P .060 which is very noisy, like a tile saw. Cuts hard agate great and the diamond matrix is about 3/8" tall, compared to 1/4" with the others. Currently using a 301C .040 which is a awesome blade. Doesn't glaze over like the others and rarely sharpen it. Cut lots of extremely hard rock with it and is not showing any wear. It's really worth the extra money. Who knows, later down the road I might find that the 301C will last twice as long or more than the others? The motors run cooler and don't bog down while cutting max size rocks. So overall it's easier on the saw and power feed motors.
I use Gem Lube from Kingsley North, which is the best water soluble coolant I've found. Better than Borax, RV anti freeze & Lube Cool. Biodegradable and dump everything behind the house and clean the saw with a garden hose. Gem Lube is great for rust protection too, never empty the tank until I do major cleaning. Blade is always sitting in it.

I was cutting Laker smalls in half with it and then I was going to tumble them to show their rings & Colors and I have some small T.Eggs too small for my 18 inch to easily cut ... the Laker that caused the fuss I cut on my 18 to see the inside of it....(between you & me I have a Laker post that will blow there minds... setting that up in a few hehe shhhh...no telling !!
