This is our most popular dicing blade. It has been the industry standard blade for dicing hard, brittle and highly crystallographic materials for over 20 years. This blade performs extremely well on materials such as glass, ceramic, sapphire and quartz. In the resinoid blade the diamond abrasives are held securely in a resin bond. As the cutting edges of the diamonds become dull the stresses on the bond increase to the point where the diamond is dislodged. When this happens a new diamond is exposed with fresh cutting edges. This "self sharpening" effect permits consistent cutting performance with minimal chipping and superior surface finish. We can also supply these blades with our unique stress relieved slots (see picture). These slots are designed to reduce the contact between the blade and the substrate. This reduces the load and contributes to the cooling of both the blade and the substrate. The slots also do a better job of cleaning the dicing residue from the kerf. The stress relief is provided by a circular cut out at the bottom of the slot. This cutout spreads the stress over a larger area which mitigates one of the primary failure mechanisms of standard slotted blades. These slots are available only on blades that are .008" thick or thicker. Since this is a hubless blade the user must have an appropriate set of flanges to allow mounting of the blade on the dicing saw. |
