This feature results in shorter grind times and longer life because the Roller 65 Shore A Workpiece WC Co Cr Hardness Thermal Spray abrasive particles remain at the "cutting" interface. Shorter grind times mean less heat generation in the Roller 25 lbs/inch Diameter 4.5" material being ground. Longer life means improved Force (30 psi on gauge) economics.
