At 12 feet 6 inches long, 1 inch wide, and 0.035 inches thick, it fits standard vertical and horizontal band saws used in metal fabrication shops, maintenance facilities, and production cutting operations. The blade features high speed steel teeth with a raker set and a variable pitch of 3 to 4 TPI, which helps reduce vibration and harmonics during the cut. Licensed HVAC shops, metalworking facilities, and general trade shops running metal-cutting band saws rely on this blade for reliable, consistent performance across a range of stock profiles.\u003c\/p\u003e\u003cp\u003eThe 21221 is suited for cutting ferrous metals such as structural steel, angle iron, and pipe, as well as non-ferrous metals including aluminum, brass, and copper tubing. The variable pitch tooth pattern minimizes blade chatter and extends blade life when cutting varying cross-sections or bundled stock. It is part of the Starrett Intenss PRO series, which is targeted at production and heavy-use shop applications where blade longevity and cut quality are priorities. This blade ships as a single welded loop ready to install on compatible machines.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBi-metal construction with high speed steel teeth bonded to a flexible back for durability and break resistance\u003c\/li\u003e\n\u003cli\u003eVariable pitch 3 to 4 TPI reduces vibration and harmonics for smoother cuts\u003c\/li\u003e\n\u003cli\u003eRaker tooth set provides consistent chip clearance in solid and structural stock\u003c\/li\u003e\n\u003cli\u003eStraight tooth form with positive rake angle improves cutting efficiency in metal\u003c\/li\u003e\n\u003cli\u003eFlexible back type allows the blade to flex around band saw wheels without fatigue cracking\u003c\/li\u003e\n\u003cli\u003eSuitable for both ferrous and non-ferrous metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use on band saws accepting a 12-foot 6-inch loop blade that is 1 inch wide.

Always disconnect and lock out power to the saw before removing the old blade or installing a new one. Wear cut-resistant gloves when handling the blade loop, as the teeth present a laceration hazard. After installation, verify blade tension and tracking according to the saw manufacturer's specifications before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 12 feet 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 0.035 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 3 to 4 (Variable Pitch)\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\u003eTooth Set\u003c\/strong\u003e: Raker\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\u003eMaterial Application\u003c\/strong\u003e: Ferrous Metal, Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Intenss PRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 21221\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51543119528242,"sku":"21221","price":150.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24200e8ad6f3281f1b5ee27144de562d_84d2bbdf-7f17-4fdc-ace6-368b7df559f0.jpg?v=1785915928","url":"https:\/\/voomisupply.com\/products\/starrett-21221-welded-bandsaw-blade-3-4-tpi-bi-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
