It carries the T400D manufacturer grade and features a PVD-applied TiAlN and TiN dual coating for extended tool life across a wide range of workpiece materials. The insert has a square shape with a 90-degree included angle, an 11-degree relief angle, and a 0.5-inch (12.70 mm) inscribed circle diameter. Thickness is 0.156 inches. The C1 chipbreaker geometry is built to manage chip flow in demanding drilling applications. Installation is performed by qualified machinists and tooling technicians in CNC and conventional drilling setups.\u003c\/p\u003e\u003cp\u003eThis insert is suited for universal material grades covering cast iron, non-ferrous metals, stainless steel, steel, and superalloys, corresponding to ISO material groups H, K, M, N, P, and S. It is intended for use in Perfomax series indexable drill bodies that accept the SPGX 12T3 insert size. Typical applications include through-hole and blind-hole drilling in production machining environments, both job shop and high-volume manufacturing. The PVD TiAlN and TiN coating combination provides thermal resistance and wear protection across these diverse material categories.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSPGX insert style with square geometry and 90-degree included angle\u003c\/li\u003e\n\u003cli\u003eT400D grade with PVD-applied TiAlN and TiN dual coating for broad material compatibility\u003c\/li\u003e\n\u003cli\u003eC1 chipbreaker geometry for controlled chip formation during drilling\u003c\/li\u003e\n\u003cli\u003e11-degree relief angle reduces cutting edge friction and heat buildup\u003c\/li\u003e\n\u003cli\u003e0.5-inch (12.70 mm) inscribed circle, 0.156-inch thickness — fits SPGX 12T3 seat size\u003c\/li\u003e\n\u003cli\u003eUniversal primary workpiece material rating covering ISO groups H, K, M, N, P, and S\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in SECO Perfomax series indexable drill bodies that accept SPGX 12T3 insert seats with a 0.5-inch inscribed circle.

Power down and de-energize the machine spindle before indexing or replacing inserts. Use the correct Torx or drive key as specified for the clamp screw to avoid seat damage. Handle carbide inserts with care — edges are sharp and the substrate is brittle under impact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPGX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: T400D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Perfomax\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.156 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: C1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Universal (ISO H, K, M, N, P, S)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 12T3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74077375\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51561885565234,"sku":"74077375","price":378.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b6cff29dd925980de2465292d765381f.jpg?v=1786469504","url":"https:\/\/voomisupply.com\/products\/seco-74077375-indexable-drill-insert-spgx12c1-t400d-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
