At 174 inches in total length and 1-1\/4 inches wide, this blade fits standard 14-foot 6-inch bandsaw machines. The bi-metal construction pairs a flexible backing with high-speed steel teeth at a variable 3-4 TPI pitch, allowing the blade to transition efficiently across varying material cross-sections. A raker tooth set and positive rake angle reduce cutting resistance and extend blade life on demanding stock. Licensed HVAC, machine-shop, and fabrication technicians rely on this blade for straight, controlled cuts through structural metals and pipe stock.\u003c\/p\u003e\u003cp\u003eThis blade is suited for metal-cutting vertical bandsaws found in commercial fabrication shops, HVAC mechanical rooms, and plumbing or pipefitting operations. The variable-pitch tooth pattern minimizes vibration and chatter when cutting structural steel, angle iron, tubing, copper, aluminum, and other ferrous and non-ferrous stock. It is not designed for contour or curved cutting applications. Its straight tooth form and raker set make it the preferred choice for production-volume straight cuts where consistent finish and blade longevity matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eBi-metal construction: flexible backing with high-speed steel teeth for durability and resistance to blade fatigue\u003c\/li\u003e\n\u003cli\u003eVariable pitch 3-4 TPI reduces vibration and chatter across different material thicknesses\u003c\/li\u003e\n\u003cli\u003ePositive rake angle promotes aggressive, efficient stock removal\u003c\/li\u003e\n\u003cli\u003eRaker tooth set supports chip clearance and consistent cut quality\u003c\/li\u003e\n\u003cli\u003eStraight tooth form optimized for linear, non-contour metal cutting\u003c\/li\u003e\n\u003cli\u003eIntenss PRO series designed for high-demand ferrous and non-ferrous metal applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a welded replacement bandsaw blade for metal-cutting bandsaws that accept a 14-foot 6-inch blade length.

Verify wheel diameter, blade guide clearance, and blade tension specifications on the specific saw before mounting. Always confirm blade tracking and tension are within the saw manufacturer's recommended range before resuming operation. Wear appropriate cut-resistant gloves and eye protection when handling or tensioning bandsaw blades.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Length\u003c\/strong\u003e: 174 inches (14 ft 6 in)\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\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\u003ePitch Pattern\u003c\/strong\u003e: Variable\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\u003eContour Cutting\u003c\/strong\u003e: No\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: 6.4 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: 20653\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51542799810866,"sku":"20653","price":215.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9b14e9c87bd7739e73bf04f71c7818db.jpg?v=1785907751","url":"https:\/\/voomisupply.com\/products\/starrett-20653-welded-bandsaw-blade-3-4-tpi-bi-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
