This single-sided, square-shaped insert carries grade 4040 carbide substrate with a multilayer CVD coating of TiCN, Al2O3, and TiN applied for wear resistance and extended tool life. It measures 3\/8 inch in length and width with a thickness of 5\/32 inch, a 1\/32 inch corner radius, and a 3\/8 inch inscribed circle. The insert features a neutral hand orientation, positive rake geometry, and a WL chip breaker for controlled chip evacuation. It is held in the toolholder by screw clamping. Installation and tool management are handled by machinists and CNC tooling technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling steel, stainless steel, and cast iron workpiece materials, corresponding to ISO material codes P, M, and K. The positive rake and WL chip breaker geometry support stable cutting action across these material groups, making it applicable in both roughing and semi-finishing passes. The 11-degree relief angle reduces friction at the cutting edge, and the maximum depth of cut reaches 0.3425 inches. The insert is compatible with SPMT-style toolholders that accept a 09T308 insert seat. It conforms to both ANSI and ISO standards under code SPMT 09 T3 08-WL 4040.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide grade 4040 substrate with multilayer CVD TiCN, Al2O3, and TiN coating\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 4 cutting edges and neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eWL chip breaker for controlled chip formation in steel and cast iron\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry with 11-degree relief angle for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3425 inches\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ANSI\/ISO code SPMT 09 T3 08-WL 4040\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SPMT-style milling toolholders accepting an 09T308 insert seat.

Use the appropriate torx or hex key to secure the clamping screw to the toolholder seat; do not overtighten. Inspect the insert pocket and seating surface for chips or debris before seating a new insert. Follow the toolholder manufacturer's torque specifications for the clamping screw.\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: 4040\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\u003eChip Breaker\u003c\/strong\u003e: WL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 09T308\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1563 inches (5\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1575 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3425 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: SPMT 09 T3 08-WL 4040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.1 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: SANDVIK COROMANT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5751066\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51736224694578,"sku":"5751066","price":457.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d44dcbeff211c2643cf781ef2c5b146_8f18b2c7-c963-461e-bc2a-dd31f6520e52.jpg?v=1788776614","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5751066-spmt-09t308-milling-insert-4040","provider":"Voomi Supply","version":"1.0","type":"link"}
