OEM Reciprocating Saw Bi Metal Blade Manufacturer & Exporter

Standard high-carbon steel (HCS) blades provide high flexural elasticity but rapidly lose tooth edge hardness at friction temperatures above 200°C, rendering them unsuitable for metal cutting. Conventional bi-metal blades use M2 or Matrix II steel, which performs well in mild steels up to 500°C. Our M42 bi-metal blades introduce an 8% active cobalt content into the tungsten-molybdenum matrix, sustaining cutting edge hardness of 67–69 HRC up to 600°C red-heat. This metallurgy cuts through high-tensile stainless steel, Cast Iron, and abrasive demolition timber 5 to 10 times longer without tooth stripping.

Yes, OEM and ODM manufacturing is our core specialty. Operating out of our Nanjing production facility with international trade offices in SIP Suzhou, we provide full customization: overall length (100mm to 300mm / 4" to 12"), blade width and thickness (from ultra-flexible 0.9mm to heavy demolition 1.6mm), specialized variable TPI (such as 10/14 or 4/6 TPI), plunge-cut tip profiles, multi-color powder coatings, client laser markings, and barcode-ready retail shelf packaging. We routinely sign comprehensive Non-Disclosure Agreements (NDAs) to safeguard proprietary client designs.

Shank failure typically occurs when the blade holder experiences violent mechanical harmonics and high cyclic shear stress. We mitigate this through three engineered safeguards: 1) Utilizing premium high-ductility D6A alloy backing steel with strict control of phosphorus and sulfur impurities; 2) Applying computer-controlled localized shank induction tempering, leaving the clamping tang at an impact-absorbing 44–48 HRC while the tooth edge remains ultra-hard; 3) Standardizing smooth-radius stress relief notches on all universal 1/2" tang geometries to eliminate sharp micro-stress risers.

For custom-branded OEM runs (laser etching + custom retail packaging), our standard production MOQ begins at 2,000 to 5,000 pieces per SKU depending on blade dimensions and coating specs. Pilot batch testing orders can be accommodated upon consultation. Lead times for reorders typically span 25 to 35 business days from final digital proof sign-off, supported by streamlined port clearance through Shanghai or Ningbo container ports.

All raw steel strip, solder flux, protective coatings, and packaging materials utilized in our manufacturing facilities undergo rigorous testing by third-party laboratories (SGS / TÜV) to guarantee compliance with EU REACH Regulation (EC No 1907/2006) for Substances of Very High Concern (SVHC) and EU RoHS Directive 2011/65/EU (including 2015/863 amendments). We provide comprehensive Safety Data Sheets (SDS) and mill test certificates with every commercial shipment.

Every production lot is cataloged by our quality assurance division with retained reference samples for a minimum of 24 months. We provide a full 1-year commercial quality warranty paired with a 3-month free return and replacement guarantee for any non-conformance regarding welding integrity, hardness parameters, or dimensional tolerances confirmed by our technical review team.
