Recommendations Start to cut material at reduced cutting rate After break-in when the blade has fully entered the work-piece, increase the feed rate over a series of cuts until the recommended cutting rate is achieved. Blade Break-In Using the right break-in procedures for a bi-metal blade ensures longer blade life, faster cuts for a longer period of time and consistent performance. Conversely, blade life can be significantly compromised if the proper break-in procedures are not followed. Softer material such as carbon steel and aluminum: A. Run the normal surface feet per minute (SFPM). B. Adjust the feed pressure to 50% the normal cutting rate for 50-100 square inches (323-645 sq.cm). C. Increase to 100% cutting rate. D. Avoid vibration. Harder materials such as nickel-based alloys like inconel, hardened steels, tool steels and stainless steels: A. Run the normal surface feet per minute (SFPM). B. Adjust the feed pressure to 75% of the normal cutting rate for 25-75 square inches (161-484 sq.cm). C. Graduallyincreasecuttingratetoreach100%after50squareinches(323sq.cm). D. Avoid vibration.
