The blade runs 10 feet in length and 3\/4 inch wide, with a 0.035-inch thickness and a variable pitch of 4 to 6 teeth per inch (TPI). The tooth material is high speed steel, set in a raker pattern with a positive rake angle for aggressive, efficient stock removal. The flexible back design reduces fatigue cracking during continuous use. Licensed HVAC, plumbing, and mechanical contractors as well as metal fabricators will find this blade well suited for structural and tubing cuts on a range of metal workpieces.\u003c\/p\u003e\n\u003cp\u003eThis blade is intended for use on horizontal and vertical metal-cutting bandsaws accepting a 10-foot blade loop. The variable pitch tooth pattern reduces harmonic vibration and improves chip evacuation across varying material thicknesses, making it a practical choice for shops cutting both solid bar stock and thin-wall tubing. Material applications include ferrous metals such as mild steel, alloy steel, and structural sections, as well as non-ferrous metals including aluminum, brass, and copper. The Intenss PRO series is designed for demanding production cutting cycles where blade life and cut quality are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eBi-metal construction with high speed steel teeth bonded to a flexible alloy back for extended blade life\u003c\/li\u003e\n  \u003cli\u003eVariable pitch of 4 to 6 TPI reduces vibration and improves cut finish across varying stock thicknesses\u003c\/li\u003e\n  \u003cli\u003eRaker tooth set with positive rake angle for efficient chip clearance in metal cutting\u003c\/li\u003e\n  \u003cli\u003eFlexible back construction resists fatigue cracking during continuous bandsaw operation\u003c\/li\u003e\n  \u003cli\u003eStraight tooth form suits general-purpose ferrous and non-ferrous metal cutting applications\u003c\/li\u003e\n  \u003cli\u003eWelded loop ready for immediate installation on compatible bandsaw machines\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit blade for metal-cutting bandsaws requiring a 10-foot welded loop, 3\/4-inch wide, 0.035-inch thick blade.

Verify wheel diameter, blade guide spacing, and throat capacity match the 10-foot loop length and 3\/4-inch width before fitting. Tension the blade according to the bandsaw manufacturer specifications and confirm blade tracking before resuming cuts. Wear cut-resistant gloves when handling coiled or uncoiled 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: 10 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 3\/4 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: 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\u003eSeries\u003c\/strong\u003e: Intenss PRO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242112\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: 20689\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51540308001074,"sku":"20689","price":110.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/24200e8ad6f3281f1b5ee27144de562d_bfae83e1-f41a-4661-8bda-cc2e35c64c1b.jpg?v=1785851745","url":"https:\/\/voomisupply.com\/products\/starrett-20689-bi-metal-bandsaw-blade-10-ft-3-4-in-4-6-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
