This single-sided, square-shaped insert features four cutting edges with a neutral rake angle, a T-Land cutting edge style, and an 11-degree relief angle. The uncoated, bright finish fine-grain carbide substrate in grade HX is suited for applications where coating is not required or where sharp edge integrity is the priority. The insert measures 3\/8 inches in both length and width, with a thickness of 1\/8 inches, and a maximum depth of cut of 0.3750 inches.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for milling cast iron, non-ferrous metals, superalloys, and titanium. It is used in production machining environments by machinists, tooling technicians, and CNC operators working with indexable face mills or shoulder mills. The SPMX-09 series insert fits toolholders within the R215.39, R215.49-3, and R417.19-3 cutter series. The chip breaker designation is 75. Typical applications include face milling, shoulder milling, and contour operations on these material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide fine-grain HX grade substrate with bright uncoated finish for sharp, consistent cutting edges\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and four usable cutting edges per insert\u003c\/li\u003e\n  \u003cli\u003eT-Land cutting edge style with neutral rake and 11-degree relief angle for stable chip formation\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3750 inches; inscribed circle diameter of 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003eScrew-held, single-sided insert with neutral hand for flexible toolholder mounting\u003c\/li\u003e\n  \u003cli\u003eISO-coded SPMX0903AP-75 with compatibility across R215.39, R215.49-3, and R417.19-3 cutter series\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with SECO cutter series R215.39, R215.49-3, and R417.19-3.

Power down and lock out the machine spindle before changing or indexing inserts. Use the correct torx or hex key specified by the cutter body manufacturer to torque the clamping screw — do not overtighten or substitute fasteners. Inspect the insert pocket and seating surface for debris or damage 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: SPMX\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\u003eMaterial Grade\u003c\/strong\u003e: Fine Grain\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 0903\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: SPMX-09\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1\/8 inches (0.1252 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1378 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.3750 inches\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 Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Neutral)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: 75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double Sided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Application\u003c\/strong\u003e: Cast Iron, Non-Ferrous Metal, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: R215.39, R215.49-3, R417.19-3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SPMX0903AP-75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SPMX0903AP-75\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 74018150\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51563674042674,"sku":"74018150","price":229.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7a5f0e1b491d75e8770f347f6a24acd3.jpg?v=1786500961","url":"https:\/\/voomisupply.com\/products\/seco-74018150-milling-insert-spmx0903ap-75-hx-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
