The TDX wheel is a new VIT Diamond wheel that uses new abrasive materials that are tough and long-lasting, and new bonds that are powerful and sharp. In addition, because it was changed to a manufacturing method that minimizes damage to the diamond due to heat, it is suitable for processing that makes use of the original sharpness of the diamond. As with conventional VIT wheels, features such as high rigidity, low thermal expansion, and pores due to integrated molding remain unchanged, so it can be replaced with conventional products.
