Product Description:

Exclusively designed for processing materials for softer high value rocks like turquoise, gaspeite, opals.

These blades are manufactured by crimping Synthetic diamonds directly into the edge of the saw blade. They are best suited for turquoise, opal, glass, and stones in the 4-6 range on the Mohs hardness scale.

We don't recommend using this blade to cut too hard materials, such as: agate and jadeite with a Morse hardness of 6-7. Because it is difficult to cut or the blade will be damaged quickly

Advantages: achieving satisfactory cutting results and reducing unnecessary material consumption.

This thin diamond lapidary saw blade offers a very good cost effective option for those that want either very thin kerfs or plan on short term use.

Used for Trimming: They are excellent for trimming small shapes into stones. 

This simply means that these blades are meant for small material, not large or slabbing techniques. Also, these blades operate in a single direction so make sure that the arrow on the blade is pointed towards you when mounting.

Use with water as a lubricant
