Diamond / CBN (Cubic Boron Nitrite)

Thode Knife and Saw Ltd hold in stock a comprehensive range of diamond/CBN grinding wheels. Diamond and CBN grinding wheels both have  similar characteristics superior to conventional abrasives . They both provide high hardness, good wear resistance, high impact strength, and good thermal conductivity. Therfore  they are called "super abrasives". For more information please download the Thode Industrial Abrasives catalogue (here)
