Remarks:
   1. Metal bonded diamond pellets normally used in first process, granularity should be selected according to the specific process, in general choose 1200# or 1500#.
   2. Resin bonded diamond pellets normally used in second process, granularity in general choose 1500#,1800# or 2000#.
   3. Even the different type glass with same abrasion resistance, their feature will be various in cold processing, please contact our technicians for advice before you choose our diamond pellets.
