Part of the Intenss PRO-VTH series, it measures 162 inches (13 feet 6 inches) long and 1-1\/4 inches wide, with a blade thickness of 0.042 inches. The M42 high-speed steel tooth material delivers heat resistance and edge retention when cutting through steel and exotic alloys. A variable pitch of 3-4 TPI, combined with a positive rake angle and ground cutting edge, promotes efficient chip evacuation and reduces vibration during contour cuts. Licensed machinists, maintenance mechanics, and metal fabricators install this blade on industrial vertical bandsaws.\u003c\/p\u003e\n\u003cp\u003eThis blade is suited for contour cutting of ferrous metals, including carbon steel, alloy steel, and exotic steel grades. The raker tooth set and straight tooth form make it effective for structural shapes, plate stock, and solid bar in both production and job-shop settings. The flexible back type helps the blade conform to curved cuts without fatigue cracking during continuous operation. It ships as a single welded loop, ready to mount without additional joining.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eM42 high-speed steel teeth for extended cutting life in hard and exotic steels\u003c\/li\u003e\n  \u003cli\u003eVariable pitch 3-4 TPI reduces harmonic vibration and improves surface finish\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle and ground cutting edge promote aggressive, clean cuts\u003c\/li\u003e\n  \u003cli\u003eRaker tooth set provides efficient chip clearance in ferrous metal cutting\u003c\/li\u003e\n  \u003cli\u003eFlexible back construction supports contour cutting without premature fatigue\u003c\/li\u003e\n  \u003cli\u003eWelded loop construction eliminates field joining and ensures consistent blade tension\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 industrial vertical bandsaws accepting a 162-inch (13 feet 6 inches) loop length and a 1-1\/4-inch blade width.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eBlade installation should be performed by a qualified machinist or maintenance technician with the bandsaw fully de-energized and locked out per OSHA lockout\/tagout procedures. Verify that blade guides, thrust bearings, and wheel tracking are properly adjusted before applying tension. Wear cut-resistant gloves when handling the coiled or uncoiled blade. Do not exceed the bandsaw manufacturer's specified blade speed for bi-metal blades cutting the intended material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 162 inches (13 feet 6 inches)\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: 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: High Speed Steel (M42)\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\u003eSeries\u003c\/strong\u003e: Intenss PRO-VTH\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\u003eWeight\u003c\/strong\u003e: 5.8 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: 21578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51541432631602,"sku":"21578","price":233.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6ee3ffa368866b490e35b3ae6f92cf3_3eeee0c2-d106-437b-8405-84b028eb1127.jpg?v=1785875984","url":"https:\/\/voomisupply.com\/products\/starrett-21578-bi-metal-bandsaw-blade-162-in-1-1-4-in-3-4-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
