Built on the Intenss PRO-VTH series platform, it measures 138 inches long, 1 inch wide, and 0.035 inches thick. The blade runs a variable 3-4 TPI pitch with a positive rake angle and ground, straight-form raker-set teeth backed by an M42 high speed steel tooth material. The flexible back construction reduces blade fatigue during extended contour-cutting operations. At 3.5 pounds, the blade is sized for floor-standing vertical bandsaws used in ferrous metal and exotic steel cutting.\u003c\/p\u003e\u003cp\u003eThis blade is suited for professional metal fabricators, maintenance technicians, and tool-and-die shops running vertical bandsaws on steel and exotic steel workpieces. The variable pitch tooth pattern dampens harmonic vibration, making it effective on solid bar stock, structural shapes, and tubing. Contour cutting is supported by the blade geometry, giving operators the ability to follow curved cut lines without significant blade deflection. It is a direct replacement or upgrade choice wherever a 138-inch by 1-inch bi-metal bandsaw blade is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eM42 high speed steel teeth for extended cutting life on steel and exotic alloys\u003c\/li\u003e\n\u003cli\u003eVariable 3-4 TPI pitch reduces vibration and improves surface finish on metal cuts\u003c\/li\u003e\n\u003cli\u003ePositive rake angle increases chip clearance and cutting aggression on ferrous stock\u003c\/li\u003e\n\u003cli\u003eGround cutting edge delivers consistent tooth geometry and uniform kerf\u003c\/li\u003e\n\u003cli\u003eFlexible back construction resists fatigue cracking during contour and radius cuts\u003c\/li\u003e\n\u003cli\u003eRaker tooth set provides balanced chip removal for general-purpose metal cutting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement bandsaw blade for vertical bandsaws accepting a 138-inch by 1-inch blade with 0.035-inch blade thickness.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eBandsaw blade replacement is typically performed by a qualified shop technician or machinist. Disconnect and lock out power to the bandsaw before opening blade guards or removing the old blade. Use proper blade-folding technique and cut-resistant gloves when handling the coiled blade. Verify blade guides, thrust bearings, and wheel tracking alignment after installation before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 138 inches (11 ft 6 in)\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\u003c\/strong\u003e: 3-4 (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: M42 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\u003eCutting Edge Style\u003c\/strong\u003e: Ground\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\u003eContour Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Steel, Exotic Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Intenss PRO-VTH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 3.5 pounds\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: 21568\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51539564855602,"sku":"21568","price":161.62,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6ee3ffa368866b490e35b3ae6f92cf3.jpg?v=1785843115","url":"https:\/\/voomisupply.com\/products\/starrett-21568-bi-metal-bandsaw-blade-11ft6in-1in-3-4-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
