The service life of bimetallic band saw blades depends not only on blade quality, but also on cutting parameters, machine adjustment and operating habits, which account for over 60% of actual service performance. Common failures such as chipped teeth, early dulling and blade breakage are frequently caused by mismatched working conditions rather than product defects.
TPI tooth pitch selection plays a key role. Use coarse teeth for solid bars and fine teeth for thin wall tubes, ensuring at least 2‑3 teeth engage with workpiece to avoid heavy impact load on single tooth. Run‑in procedure is essential for new blades: reduce feed rate for initial cuts to prevent micro‑chipping on cutting edges.
Set proper cutting speed and feed pressure, and guarantee sufficient coolant to remove cutting heat. For high hardness mold steel and alloy steel, M51 high cobalt blades are recommended for superior hot hardness performance.
