Industrial saw blades are the core consumable for metal fabrication, pipe mills and timber processing, where correct grade selection directly controls production cost, cut precision and service life. At www.jinzhi-steel.com, Hangzhou Jinzhi Steel supplies JINBIRD® bi‑metal, HSS and TCT saw blades tailored for global workshop and factory demands, covering both standard stock and custom non standard solutions.
Bi‑metal band saw blades remain the mainstream choice for general metal cutting. M42, with 8% cobalt and hardness HRC 67–69, balances impact toughness and cost efficiency. It works reliably for carbon steel, low alloy bars, steel pipes and ordinary stainless steel, which makes it the most popular option for daily batch cutting. M51 contains 10% cobalt, delivering better hot hardness under sustained high cutting temperature. It is preferred for difficult to machine materials such as 304 / 316 stainless steel, die steel and high‑strength alloy, resisting thermal softening and tooth abrasion during long time running.
For higher requirements of speed and surface finish, tungsten carbide tipped (TCT) circular blades stand out. The brazed carbide tips hold sharpness far longer than high speed steel, supporting fast cold cutting on solid bars and profiles. Meanwhile, friction hot saws serve high speed flying cut off lines for steel tube production, operating at line speeds from 90–120 m/s. This cutting method relies on friction heat to melt the cutting zone, generating heavy sparks and requiring stable blade body strength to avoid cracking under thermal shock. Tooth configuration is critical: 32T and 36T designs carry different carbide consumption, which naturally creates price gaps even with identical outer dimensions.
Many overseas buyers overlook the importance of matching tooth pitch, blade tension and coolant to workpieces. Improper matching causes early chipping, sudden breakage and burrs, raising overall processing expense. Modern buyers increasingly demand flexible customization: special lengths, custom tooth profiles, laser marking and small trial orders, not only bulk shipments.
Founded in 2008, Jinzhi Steel runs an automated factory with strict full process inspection, from raw material incoming test, CNC tooth grinding and welding to final hardness and run out checking. As raw material prices of tungsten carbide fluctuate frequently, valid quotation periods help both buyers and manufacturers lock stable terms. Professional saw blade suppliers provide not only products, but also application guidance to help clients select the right blade grade and cutting parameters for their machines and materials.
