The blade runs 12 feet in length, 1-1\/4 inches wide, and 0.042 inches thick. It features a variable pitch tooth pattern in the 4 to 6 TPI range, which helps reduce vibration and noise during the cut while improving chip clearance. High speed steel teeth are electron-beam welded to a flexible alloy steel back for durability under the repeated flex stress of bandsaw operation. The raker tooth set and positive rake angle promote aggressive, efficient cutting in production and job-shop environments. Licensed HVAC, plumbing, and mechanical contractors as well as metalworking shops will find this blade suited to general structural and pipe cutting tasks.\u003c\/p\u003e\u003cp\u003eThe STARRETT 20730 is intended for metal-cutting band saws used in commercial and industrial settings. Its bi-metal construction makes it appropriate for a broad range of metal stock: structural steel, angle iron, pipe, tubing, aluminum extrusions, brass, and similar ferrous and non-ferrous materials. The variable pitch design makes it particularly effective on interrupted cuts, bundles, and varying cross-sections where a fixed-pitch blade tends to chatter. It is sold as a single welded loop ready to install without additional joining.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBi-metal construction: high speed steel teeth bonded to a flexible alloy steel back for extended blade life\u003c\/li\u003e\n\u003cli\u003eVariable pitch 4 to 6 TPI reduces vibration and chatter on irregular or varying cross-section cuts\u003c\/li\u003e\n\u003cli\u003ePositive rake angle and raker tooth set promote fast, clean chip removal in ferrous and non-ferrous metal\u003c\/li\u003e\n\u003cli\u003eStraight tooth form with flexible back type suited to contour-free, straight production cuts\u003c\/li\u003e\n\u003cli\u003ePre-welded loop: 12 feet long, ready to install directly onto compatible band saw wheels\u003c\/li\u003e\n\u003cli\u003eIntenss PRO series designation indicates suitability for demanding production-volume cutting cycles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or production-stock welded bandsaw blade for metal-cutting band saws accepting a 1-1\/4 inch wide blade in a 12-foot loop length.

Disconnect and lock out power to the saw before opening the blade guards or removing the existing blade. Wear cut-resistant gloves when handling the coiled blade; the teeth are sharp and the loop can spring open unexpectedly. After seating the blade on the wheels and threading it through the guides, set blade tension and tracking per the saw manufacturer specifications before restoring power and making a test run.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 12 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 0.042 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 4 to 6 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\u003ePitch Pattern\u003c\/strong\u003e: Variable\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\u003eContour Cutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Intenss PRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242112\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: 20730\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539141427506,"sku":"20730","price":183.14,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24200e8ad6f3281f1b5ee27144de562d_47b6cb77-9f33-4b7b-ab59-b6fb78a4f471.jpg?v=1785835274","url":"https:\/\/voomisupply.com\/products\/starrett-20730-bi-metal-bandsaw-blade-12-ft-1-1-4-in-4-6-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
