PR1525 Chip evacuation rate = 720cc/min PR1535 Chip evacuation rate = 58cc/min
Competitor G Chip evacuation rate = 240cc/min Competitor H Chip evacuation rate = 36cc/min

• Small machining noise even at 3 times higher feed rate • Competitor H caused chattering but MFH realized stable machining
• Good edge condition without chipping and stable machining • Good edge condition and long tool life
