high quality disc -superior coolant system

high quality disc are designed to work on virtually any material you can find. You can cut very hard materials, than switch to cutting very soft materials and the cutting blades will maintain the same consistent performance. 7mm diamond depth allows the blade to last 80% to 40% longer on the hardest materials.  superior coolant system - these blades are designed to cut with or without oil. We feel it is more preferable to the user to use water as a coolant. Oil does not a proper coolant for this procedure, as most other manufacturers would suggest. Water is a true organic coolant, witch does not leave the material being cut oily or greasy.
