As we have stated earlier in the other section, out of the numerous Diamonds coated drilling and cutting tools, most prominent are the of types: Metal Bond technology tools and Electro-bond technology tools, which dominates the world market. 

In metal bond technology tools, diamond particles are sintered with metal alloys and impregnated in the tool tips, which is later brazed to the tool. 

On the other hand, in Electro-bond technology tools, diamond particles are Electro-deposited to the tip of the tools. Electro-bond diamond tools have high diamond concentration and, hence ensure freer and faster cutting without exit chipping and high precision. It is comparatively economic and can be fitted to any normal, portable electric drill. The heat generation while cutting is too minimum. If you have only less than 100 holes to drill, Electro-bonded diamond drills are the best solution both economically and on usage basis. 

Excel Abrasives have a wide range of high precision Electro-bonded Diamond tools for various drilling, cutting, grinding and other numerous applications on surfaces like glass, granite, marble, cuddappah, FRP, FTP, semi-precious stones etc.
