Sustained Cut Rate (g per cycle)
Total Material Removed: 60+ Stainless Steel: The ‘total material removed’ claim is determined by averaging the amount of metal ground over 40 cycles, approximately 8.5 minutes of grinding 80+ Stainless Steel: The ‘total material removed’ claim is determined by averaging the amount of metal ground over 72 cycles, approximately 15 minutes of grinding
Sustained Cut Rate: 60+ & 80+ Stainless Steel: The ‘sustained cut rate’ claim is determined from averaging the cut/cycle from cycles 5-24 (20 cycles total, which is approximately 4 minutes of grinding) Units for stainless steel will be (Grams/cycle)
Units for stainless steel will be Grams Each cycle for the stainless steel test method = 12.7 seconds of grinding per cycle
