It carries the SPMT0808-BR 4425 designation and features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN for wear resistance and thermal stability when cutting steel. The insert measures 8.90 mm inscribed circle (0.3504 inches), 3.00 mm thick (0.1181 inches), and has a 0.80 mm corner radius (0.0315 inches). With a positive rake geometry and an 11-degree relief angle, this insert is suited for general-purpose steel machining at moderate to high cutting speeds.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in the CoroBore 111 series boring system. It fits clamp and screw-style insert holders and is rated with a primary workpiece material code of P, meaning it is optimized for machining steel grades including unalloyed, low-alloy, and high-alloy carbon steels. The BR chipbreaker geometry is designed for controlled chip formation across a range of depths of cut and feed rates, making it a reliable choice for production boring on CNC lathes and machining centers. Four neutral cutting-direction edges are available per insert.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer TiCN\/Al2O3\/TiN coating for extended tool life in steel cutting\u003c\/li\u003e\n  \u003cli\u003eSquare SPMT insert shape with 4 usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with 11-degree relief angle for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eBR chipbreaker for controlled chip evacuation at moderate feeds\u003c\/li\u003e\n  \u003cli\u003eCompatible with clamp and screw insert-holding methods\u003c\/li\u003e\n  \u003cli\u003eNeutral cutting direction suits a wide range of boring configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with the CoroBore 111 boring system.

Use the correct torque driver or wrench specified by the toolholder manufacturer when securing the clamping screw — do not overtighten by hand. Inspect the insert seat and clamping pocket for chips or debris before seating the insert. Index or replace the insert when measurable flank wear or surface-finish degradation is observed; do not continue running a failed edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\/Al2O3\/TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 8.90 mm (0.3504 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 3.00 mm (0.1181 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm (0.0315 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: BR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp; Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (Code P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 3.74 inches (L) x 1.58 inches (W) x 0.55 inches (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SPMT0808-BR 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SPMT0808-BR 4425\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 7860968\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51755417436466,"sku":"7860968","price":308.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/eaf328625582832c2512aea7e8887608.jpg?v=1788954808","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-7860968-boring-insert-spmt0808br-4425","provider":"Voomi Supply","version":"1.0","type":"link"}
