It is a square-shaped, single-sided insert with a 90-degree included angle, four cutting edges, and a positive rake geometry. The TiAlN PVD coating and submicron carbide substrate are matched to demanding milling applications across a broad range of workpiece materials. The insert seats in a screw-clamped pocket and is sized at 0.4016 inches wide and 0.1670 inches thick, with a corner radius of 0.0315 inches (1\/32 inch). It is installed by licensed machinists and CNC tooling professionals in production milling operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling steel, stainless steel, cast iron, superalloys, titanium, and hard materials, covering ISO material groups P, M, K, S, and H. The HQ chip breaker geometry promotes controlled chip formation across these material classes. The T-Land cutting edge style provides edge stability under interrupted cuts and variable feed conditions. The insert is right-hand oriented and belongs to ISCARs HELIQUAD series, making it applicable in face milling, shoulder milling, and similar toolpaths where consistent depth-of-cut control is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC908 grade: submicron solid carbide substrate with TiAlN PVD coating for extended tool life in steel and hard materials\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges on a square single-sided insert body for cost-effective edge utilization\u003c\/li\u003e\n  \u003cli\u003eHQ chip breaker with T-Land edge style for stable, controlled cutting across multiple material groups\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry reduces cutting forces and heat generation at the workpiece interface\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.3150 inches with an effective cutting edge length of 0.3701 inches\u003c\/li\u003e\n  \u003cli\u003eScrew-clamped insert holding method compatible with HELIQUAD series cutter bodies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with ISCAR HELIQUAD series cutter bodies designated FSB, SSB, SPK, F90SP, and E90SP that accept SPMT 100408 pocket geometry.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Disengage and lock out the machine spindle before seating or removing inserts. Use the correct torque driver and clamping screw specified by the cutter body manufacturer to avoid insert rocking or screw damage. Inspect the pocket seating surface for chips or debris before installing a new insert to ensure full contact and accurate edge positioning.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: SPMT 100408TR-HQ-M IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: SPMT 100408TR-HQ-M\u003c\/li\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: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Submicron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.4020 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.4016 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1670 inches\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\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.3701 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3150 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: T-Land\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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\u003eSeries\u003c\/strong\u003e: HELIQUAD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5604294\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51737055101234,"sku":"5604294","price":244.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ba44d1eb8159d33e92fae6dad5348ac.jpg?v=1788783678","url":"https:\/\/voomisupply.com\/products\/iscar-5604294-milling-insert-spmt-100408tr-hq-m-ic908","provider":"Voomi Supply","version":"1.0","type":"link"}
