The coil format allows fabricators and machinists to cut blades to custom lengths, making it a practical choice for facilities running multiple saw sizes. The blade measures 3\/4 inches wide and 0.032 inches thick, with a 6 teeth per inch (TPI) constant pitch and a raker tooth set. The flexible back design reduces fatigue cracking during operation, extending blade service life under repeated use. Typical installers are machinists, metalworkers, and shop technicians who weld their own blades in-house.\u003c\/p\u003e\n\u003cp\u003eThis coil stock is suited for contour cutting applications where a consistent, straight tooth form delivers controlled chip removal. The 6 TPI pitch is effective on medium-section stock, balancing cut speed with surface finish. The raker set pattern alternates teeth in a right-left-straight sequence, which clears chips efficiently and reduces heat buildup in the cut zone. The 100-foot coil length provides enough material to yield multiple blades, making it cost-effective for shops that maintain a high blade turnover or service band saws of varying wheel diameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCarbon steel construction with flexible back for resistance to fatigue cracking\u003c\/li\u003e\n  \u003cli\u003e6 TPI constant pitch for consistent chip load on medium-section workpieces\u003c\/li\u003e\n  \u003cli\u003eRaker tooth set for efficient chip clearance and reduced heat in the kerf\u003c\/li\u003e\n  \u003cli\u003eStraight tooth form and straight rake angle for controlled, predictable cuts\u003c\/li\u003e\n  \u003cli\u003eContour cutting capable, suitable for curved and irregular cut profiles\u003c\/li\u003e\n  \u003cli\u003e100-foot coil yields multiple custom-length blades from a single stock unit\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a coil stock replacement for band saws accepting 3\/4-inch wide blades with a 0.032-inch blade thickness.

Disconnect and lock out the band saw from its power source before installing or tensioning any blade. Verify that blade width, thickness, and tooth set are compatible with the saw's guide assemblies and blade guards before running the machine. Follow the saw manufacturer's tensioning guidelines and confirm blade tracking before resuming production cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Material\u003c\/strong\u003e: Carbon Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Width\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Thickness\u003c\/strong\u003e: 0.032 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoil Length\u003c\/strong\u003e: 100 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTeeth Per Inch (TPI)\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch Pattern\u003c\/strong\u003e: Constant\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: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBack Type\u003c\/strong\u003e: Flexible\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Toothed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContour Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTip\/Edge Material\u003c\/strong\u003e: Carbon Steel (no added tip material)\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: 13840\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"STARRETT","offers":[{"title":"Default Title","offer_id":51544482808114,"sku":"13840","price":496.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1286cf999cb954395876c767772f64f9.jpg?v=1785927650","url":"https:\/\/voomisupply.com\/products\/starrett-13840-band-saw-blade-coil-3-4-in-100-ft-6-tpi","provider":"Voomi Supply","version":"1.0","type":"link"}
