Manufactured to grade 235 with a CVD-applied TiCN and TiN dual coating, this insert delivers wear resistance suited to demanding cutting environments. It features a square shape with a 90-degree included angle, four cutting edges, and a corner radius of 0.0591 inches (1.50 mm). The positive rake geometry at 15 degrees and the WM chip breaker promote controlled chip flow during face milling, shoulder milling, and similar operations. Installation and replacement are handled by licensed machinists and CNC setup technicians.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in milling cutters that accept SEKR-style square inserts with a 12.70 mm inscribed circle (0.5000 inches). It is suited to both residential machine shops and commercial production environments where P- and M-category workpiece materials — steel and stainless steel — are regularly machined. The insert size code is 1203, and it carries ANSI and ISO designations of SEKR 12 03 AZ-WM 235, making direct catalog cross-referencing straightforward. The neutral hand orientation allows use in standard cutter bodies without handedness restrictions. Maximum depth of cut reaches 0.2520 inches (6.40 mm).\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiCN and TiN dual coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges per insert with single-sided geometry, maximizing insert value per unit\u003c\/li\u003e\n  \u003cli\u003ePositive 15-degree rake angle reduces cutting forces and heat generation at the workpiece interface\u003c\/li\u003e\n  \u003cli\u003eWM chip breaker geometry promotes controlled chip formation across a range of feed rates\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0591 inches (1.50 mm) provides edge strength while reducing surface stress concentrations\u003c\/li\u003e\n  \u003cli\u003eANSI and ISO dual-standard designation (SEKR 12 03 AZ-WM 235) supports cross-platform cutter compatibility verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in indexable milling cutter bodies that accept SEKR-series square inserts with a 1203 insert size code and a 0.5000-inch inscribed circle.

Before indexing or replacing inserts, ensure the machine spindle is fully stopped, locked out, and the cutter body is secured in a vise or fixture. Use the correct torx or hex key specified by the cutter body manufacturer for the clamping screw — do not substitute tools. Inspect the pocket seat and clamping components for wear or debris before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SEKR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: 235\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square\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 and TiN (CVD process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1203\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 (9.60 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches (3.17 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0591 inches (1.50 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2520 inches (6.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 20 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Corner Rounded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SEKR 12 03 AZ-WM 235\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SEKR 12 03 AZ-WM 235\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23291601\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.15 pounds\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\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: 5749679\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SANDVIK COROMANT","offers":[{"title":"Default Title","offer_id":51733349794098,"sku":"5749679","price":423.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dc36c3933678ca7998bf2b8429d25d42.jpg?v=1788754526","url":"https:\/\/voomisupply.com\/products\/sandvik-coromant-5749679-milling-insert-grade-235-sekr","provider":"Voomi Supply","version":"1.0","type":"link"}
