Also, for a 6" trim saw for more costly rough (less waste  )-what blade would you recommend? |

You might try dressing your 301 blade and tapping edge flat if it is rounded. I have cut a lot of rocks with a 301 on my MK101 tile saw and the cut is as flat as my wallet. If you are hand slabbing without a vice you will get saw marks with any blade you try. If you are pushing a vised rock through by hand make sure vice is not lifting or rock moving in vise. Also saw bearings not worn and letting blade run off. Ah ha, you guessed it. The 301 is rounded off. I have been cutting a lot of obsidian with it between other cuts, so it should be dressed. I did not think about side blade dressing/flattening. I have a pretty good vice and slide system om the saw, and the bearings are nice and tight. No blade play at all. I think it is a problem with the rounded 301 blade, as I get streaky cuts. I am building a DYI Rchardsons style dry sander to take care of those though  One lapidary tool leads to needing another... |

To follow up on this thread, I ordered the MK Diamond 0.032 8" 303 blade from Amazon. I used the 'slow' free shipping option on Amazon and it was sent to me in 4 days after ordering it. I ~just~ installed it this afternoon and I ran though several pieces of gold sheen obsidian with it. Very smooth and fairly fast cuts, even free-hand! I then cut up a small piece of pet wood. Slicey dicey! So I am happy with it. Only faint saw marks, no digs like with the 301 blade. Now my arms are covered in mineral/baby (2:1 mix) oil... I guess I will take Roman baths while cutting rocks?

Don't let this info out but the "Agate Kutter" is the MK225 with BD label. I answered this question in a PM but answered .040" 303C good choice, 305 Agate Kutter good but thick, and my personal favorite 10" blade is the 301 .040".

I answered this question in a PM but answered .040" 303C good choice, 305 Agate Kutter good but thick, and my personal favorite 10" blade is the 301 .040". Is that the same as the MK 'Hot Dog' blade? The BD 305 Agate Kutter in 8" is an 050 blade ($69 from BD direct). MK 225 Hot Dog in 8" is also a 050 kerf ($60 on Amazon). MK 303 is not available in 040 in an 8", only the MK 301. In 10" there are different kerfs available. At least with what I can find online.
By the way, the Barracuda Diamond blades are not to be confused with the Power Rangers Barracuda Blade here
