Import Bandsaw Blade — Buy in wholesale FOB from Supplier in China

Hunan L.W.L Saw & Mfg. Co., Ltd manufactures bi-metal bandsaw blades in Changsha, Hunan Province, China, using imported M42 high-speed steel for the tooth edge. M42 contains approximately 8 to 10 percent cobalt by weight, giving a tooth hardness around 67 to 69 HRC and red-hardness retention at elevated cutting temperatures. The backing steel is a flexible alloy, typically chrome-vanadium or similar fatigue-resistant grade, electron beam welded to the hardened tooth strip to allow tensioning around small wheel diameters without cracking. The source description refers to precision ground teeth and multiple sizes, though exact dimensions, tooth pitch series and width increments are not listed and must be requested.

Bi-metal construction addresses a common failure mode in monometal blades: hard teeth require brittle substrate material, but a stiff back cannot withstand the cyclic flexing of bandsaw operation. By combining a tough, flexible back with a separate high-wear tooth edge, service life in alloy steel, stainless steel and tool steel cutting extends by factors of two to five compared with carbon blades. Tooth geometry options include standard, skip and variable pitch; variable pitch reduces harmonic vibration and is preferred for bundle cutting and structural sections. Set type, rake angle and gullet depth determine chip formation and cooling efficiency, particularly in flood-cooled metal cutting applications.

Target buyers include metal fabrication workshops, steel service centres, automotive component manufacturers and machine shops cutting solid bars, tubes and structural profiles. Wood processors running high-volume resawing or pallet dismantling may also source these blades if tooth pitch and gullet capacity suit their chip volume. When importing from Hunan L.W.L Saw & Mfg. Co., Ltd., buyers should confirm the M42 supplier and batch traceability, request tooth hardness test reports, and validate that the weld zone is properly annealed to prevent fatigue fracture. Packaging, shipping terms, lead time and payment conditions are not specified in the listing and require direct confirmation.

Hunan L.W.L Saw & Mfg. Co., Ltd is registered at R1601, Xintian Building, Shaoshan Road N, Changsha 410011, Hunan, China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and zero recorded average response hours. This indicates that either the profile has not yet generated response data, or communication channels have not been tested through the platform. Buyers should initiate direct contact, preferably by email and telephone to the address provided, and evaluate technical response quality before considering a purchase commitment. The listing does not indicate whether the company is a manufacturer, trading company or hybrid operation.

No information is provided about year of establishment, factory floor space, number of employees, annual turnover, export markets served, or named OEM or end-user clients. The source description mentions verified suppliers and export quality, but these are platform marketing phrases rather than supplier-specific credentials. No ISO 9001, ISO 14001, CE marking or other certification is confirmed in the profile. Buyers requiring quality system assurance should request a current quality certificate, scope statement and last audit date directly from Hunan L.W.L Saw & Mfg. Co., Ltd., and verify authenticity with the issuing body where possible.
