Hubless Resinoid Blades

• Self Sharpening
• Minimum Chipping, Superior Finish
• Time Tested Design
• Widely Used in Production Environments
• Used on Glass, Ceramic, Sapphire and Quartz

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.
