Bi-metal band saw blades are the mainstream choice for metal cutting workshops. JINBIRD M42 and M51 blades, manufactured by Hangzhou Jinzhi Steel, combine high-speed steel teeth and flexible spring steel backing. This structure balances sharp cutting performance and anti-breakage toughness, suitable for carbon steel, alloy steel, stainless steel, solid bars and steel pipes.
The correct tooth pitch selection is the core rule. Thick solid workpieces need fewer teeth per inch to avoid tooth overload; thin-walled tubes require more teeth to prevent tooth stripping. Before cutting, operators must set proper blade tension and cutting speed. Improper tension is the top cause of premature blade fracture.
For overseas buyers, matching blade specs with band saw machine models is essential. Jinzhi Steel provides full technical datasheets and custom sizes for project orders. For small-value orders, the company recommends T/T terms rather than L/C, to save unnecessary bank charges for both parties. Visit www.jinzhi-steel.com for more technical guides.
