Many fabricators overlook blade break in, which directly decides bimetallic band saw blade lifespan. Direct full load cutting on new blades easily causes tooth chipping, early dulling and unexpected fracture, raising production cost significantly.
For M42 and M51 bimetallic saw blades, reduce feed rate by 50% for the first 10‑15 square inches of cutting work. Keep original cutting speed and sufficient coolant during this phase. Gradually restore full feed load after tooth tips form smooth wear in surface.
Proper break in lowers thermal stress on tooth tips and avoids micro cracks. Jinzhi Steel (JINBIRD) recommends this standard procedure for all new bimetallic blades.
