1) Vortex 2 technology combines specially engineered abrasive grain and a new bond formula to significantly increase metal removal rates, improve profile holding, and increase wheel life by up to 40%. 2) Testing showed the Vortex 2 wheel provided 40% higher metal removal rates, better profile holding even at high speeds, and lasted 35% longer than standard Vortex wheels. 3) The innovative bond and 3D grain structure maximize coolant access during grinding, providing benefits such as reduced cycle times, lower costs, and gentler dressing.
