The blade measures 64.5 inches in length and 0.5 inches in width, with a 0.025-inch thickness and a constant 18 TPI pitch. The cutting teeth are manufactured from M42 high-speed steel, a cobalt-bearing grade that holds an edge under heat and friction. The wavy tooth set and positive rake angle work together to reduce vibration and improve chip clearance on both ferrous and non-ferrous metals. This blade is part of the Intenss series and is sold as a single unit.\u003c\/p\u003e\n\u003cp\u003eThis blade is suited for contour cutting operations on ferrous metals such as mild steel, tool steel, and structural sections, as well as non-ferrous metals including aluminum, brass, and copper. The constant 18 TPI pitch makes it well matched for thin-wall tubing, bar stock, and light structural shapes where consistent chip load is required. It is a ready-to-install welded blade intended for portable or bench-top bandsaw machines used by metal fabricators, maintenance technicians, and industrial tradespeople.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 high-speed steel teeth for extended cutting life on hard and abrasive metals\u003c\/li\u003e\n  \u003cli\u003eConstant 18 TPI pitch optimized for thin-wall tubing and light bar stock\u003c\/li\u003e\n  \u003cli\u003eWavy tooth set reduces vibration and improves finish quality\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle promotes aggressive, efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eFlexible back construction resists fatigue cracking on tight contour cuts\u003c\/li\u003e\n  \u003cli\u003eWelded blade ships ready to install with no field joining required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement welded bandsaw blade for portable and bench-top metal-cutting bandsaw machines that accept a 64.5-inch blade loop with a 0.5-inch width.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified technician following the bandsaw manufacturer's blade-change procedure. Power down and lockout the machine before removing the old blade or threading the new one. Verify blade tension and wheel alignment per the machine manufacturer's specifications before resuming cutting operations. Eye protection and cut-resistant gloves are required when handling bandsaw blades.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 64.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 0.025 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Constant\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Bi-Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Material\u003c\/strong\u003e: High Speed Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: M42\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Set\u003c\/strong\u003e: Wavy\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Form\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTooth Rake Angle\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Flexible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Toothed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContour Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Ferrous Metal, Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Intenss\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: STARRETT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540874658098,"sku":"16421","price":66.8,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ba126aeca18f78e046eb323bf66af914_1eb6264b-3568-41d3-8973-311a97c7f3d4.jpg?v=1785865221","url":"https:\/\/voomisupply.com\/products\/starrett-16421-welded-bandsaw-blade-18-tpi-bi-metal-m42","provider":"Voomi Supply","version":"1.0","type":"link"}
