40"x1.26"x0.80" 5pcs Thick Notched Coarse Cut Diamond Saw Blade

These diamond saw bladesare designed for professional use and are made with high-quality materials. The Diamond Coarse Cut Notched Saw Bladesare manufactured by crimping synthetic diamonds directly into the edge of the saw blade, making them ideal for cutting materials such as turquoise, opal, glass, and stones in the 4-7 range on the Mohs hardness scale. These blades are faster than regular notched rim bladesand come in smaller sizes with thin cores to minimize material loss when cutting valuable materials.The Thick Notched Diamond Saw Blades are made with high-quality diamond grit (120#) that is pressed onto a solid steel core, making them ideal for industrial lapidary cutting and slabbing of agates, jades, and geodes. These blades have thick kerfs and stiff cores, and all of them have a 25mm hole that can be used with 3/4", 5/8" arbors, and 1/2" bushings. It is important to use a lubricant such as water or oil when using these blades and to never run them dry. Using a good quality cutting oil can enhance the performance and lifespan of the blades. Following the recommended operating speeds and spin-drying the blades after use can prevent rusting.
