b'esouRces and ecommendationsr eCommendATionsB lAdeB reAk -i n R R 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:New blade with Tooth correctlyTooth incorrectly razor sharp teeth broken in broken inA. 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. Gradually increase cutting rate to reach 100% after 50 square inches (323 sq.cm).D. Avoid vibration. Start to cut material at reduced cutting rateAfter 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.58'
