This listing is for one of our Brazed Diamond Core Bit - 1 Inch. These are brazed core bits-- the fastest cutting core bit on the market because they have a 100% diamond exposure. They can be run wet or dry in a drill or a grinder and because they have diamond protection down the sides of the core they will never bind up on you!!! We field-tested these bits on slab granite and were getting 70 holes per bit, at cutting speeds you won't believe. These bits work on tile, marble, granite, even glass!!! Other sizes available in our online Ebay store. Brought to you by Diamante Italia-- a line of products that delivers amazingly professional results.
