A good blade to have when needed
It's much louder, but it does not wander as much. I have that problem primarily with rough rocks which catch on the saw table surface.I had bought someone else's diamond blade but the cutting area was thinner than the body of the blade and it kept pinching off. The Thicker blade solved that problem. Then I went to the sintered blade that came with the saw. It also worked, but there was a tendency to wander and I had to be much more careful about that. To be clear, as far as I can tell, the blade doesn't wander, the rock wanders as I feed it. I'm glad I have the thicker blade and I'll use it when necessary. I'm working almost exclusively with jasper.

Just what I needed
Bought the 6 inch trim saw with the thin sintered blade. While it works well on cut to size slabs, the thin sintered blade wanders on some larger cuts. The thick blade still takes time, but provides more structure to the cuts. Meets the need, but don';t expect to do big rocks with this blade and saw. I would suggest this is the first accessories to buy with the 6 inch trim saw.

Top shelf service and quality lapidary products
Can't say enough good things about Hi-Tech Diamond....the customer service is the BEST, Jennifer and Tori are always helpful and accommodating. I am new to this 6" Saw machine, but I can appreciate the value, how quiet the machine is and how great it cuts. I cut agates, chalcedony, petrified wood. I addition, I have the slant cab machine which is also excellent. I am very impressed with Hi-Tech. Quality products, attention after the sale, prompt to respond, honest and ethical! MADE IN THE USA!!!!
