Review: It works well - I have many years of lapidary experience. I did not like the results of using a tile saw for fine cutting and did not want to switch to a messy oil bath type, so I got the Hi-Tech. The kerf is easily 1/3 of that on my tile saw with a good Lapidary Hot Dog blade. It makes less than half the noise and the noise is easier to listen to than the vibrating grind of the tile saw. The blade is extremely thin, about like the thickness of the paper on a greeting card. However, when it is spun at 3,400 RPM it becomes somewhat rigid. I cut a number of shapes from my slabs and it cuts well. It was slightly slower cutting than with the tile saw, but it is a much more even, precise and smooth cut. With the tile saw I had to cut just off the outline and then later grind to it. With the precision of this saw I will cut much closer to the line. The kerf is much smaller than the ones made by tile saws. I would never cut anything over a half inch thick with this saw, but all my slabs are a quarter inch or thinner. As I am cutting geometric shapes I sometimes have to start on an angle. When this happens the blade wants to bend and not start the cut. I just applied a little pressure on the blade with my finger and the blade bit in. Once there was a 1/16th inch slot the blade held true on its own. The water reservoir is only 8 ounces, but that is plenty. I added no more than 3 ounces of water and made several cuts. When I was done I used a turkey baster to suck the remaining water out. The tile saw has a chrome plated metal surface that blares light back at you. This saw has a black plastic top that has no glare, making it easier to see what you are doing. Of course, it will never rust. It comes with a nifty splash guard that would be nice if it did not get in the way. It is only a few inches in front of the blade, so there is no room to hold the rock. But, it is easy to remove. When water flows off the top it collects in a channel and drops back into the pan, cutting down on water loss. The saw is half the size and weight of the tile saw. For what I am doing it will be great. The blade is easy to access and change. I like just about everything on the saw. My one reservation is how long the blades will hold up. Time will tell. It comes with a 5" and 4". Right now I am using the 5". I will soon try the 4" to see how I like it. Replacement blades are either $5 or $6 from Hi-Tech Diamond. It is smaller, lighter, much quieter and cuts thinner with smooth precision. It also sprays a lot less water around. You have to be a bit more gentle than with a tile saw, but it makes the cut. So far I am a very happy Rockologist.
Review: Nice lapidary trim saw with precision and quiet performance. - I was very impressed with this little rock trim saw. It is actually fairly quiet and it cuts a rock perfectly and trims the end of the cut that larger rock saws may leave behind. It is easy to adjust the wheels and they are easy to remove. It functions better than I expected and it is small enough to be very portable. i can use it inside and outside the house depending on what I am doing. It takes very little water to use it and it is easy to add water as it gets sprayed out. It seems that the construction and the motor are well made and should be durable. For small stone cutting/trimming this is a good value for the money.

## Questions & Answers

**Q: why is this better than a tile saw?**
A: Thank you for your inquiry. That is a question many people have, and while many people use tile saws to cut stone, we can not recommend this. Many experts in the lapidary field advise against using them for safety reasons. For practical reasons, here are a few reasons the 4/5" trim saw would be preferable. All Hi-Tech Diamond saw machines run quieter and are less messy to operate, which means they can be used indoors.  Additionally, the trim saws run at a slower RPM and use thinner blades, allowing for less loss of material and cleaner thinner cuts. There is a great video discussing the pros and cons of these saws by YouTuber Currently Rockhounding that you may find very helpful as well.

**Q: Can we use water with the blade or must we use oil?**
A: Yes, you can use water with this blade and machine. We actually recommend using water vs. oil because it's cleaner to work with.

**Q: Does it comes with holder for small sample pieces, picture with fingers looks dangerous ?**
A: No, it does not come with a holder. It is very difficult to get hurt when you run a diamond blade with water, which is what this saw requires.

**Q: Does this plug in a normal socket?**
A: Yes, but we highly encourage using a GFCI outlet.

### ⭐⭐⭐⭐ Cutting stone
*by A***R on May 26, 2024*

Receive it and tried it???? Hard to cut straight line? Set scew on arbor closes to box, was ok- set screw closes to blade lined up In front of arbor??? Upon inspection motor was set too far back? Fingers are very close to blade when cutting?? There is no guide ???? So it’s a lot of money for what you get- there is not thought for safety? Yes they say a child can use it???? Be careful! I do not recommend this one! You need a guide— Arbor has to be line up perfect or blade will hit table?? Little hole to get to adjustment screw is too small??? You cannot adjust arbor set screws from hole?? To put blade on arbor, very little room? Yes you need to put grease on arbor shaft. For the money you spend, its really not worth it??? Taking blade off, does not come off easy??? So think twice before you buy it— I do not put a lot of pressure when I cut?? Whom ever inspected the one I bought should not be working there???
