The insert features a 90-degree square shape with a 0.031-inch corner radius and a 9.52 mm (0.375 inch) length and width, with a thickness of 5.00 mm (0.197 inch). The IC830 grade uses a PVD-applied TiAlN\/AlTiN\/TiN multilayer coating marketed under ISCAR's SumoTec designation, providing a combination of wear resistance and toughness suited for interrupted and continuous cuts. Licensed machinists and toolroom technicians install this insert in compatible ChamTurn toolholders for finish to medium machining passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is optimized for turning steel (ISO P), stainless steel (ISO M), special and super alloys (ISO S), and hardened materials (ISO H). The SM chip breaker geometry supports finishing and medium machining operations with a maximum depth of cut of 3.00 mm (0.118 inch). It carries a negative side clearance and is suitable for applications demanding moderate to high wear resistance with maintained toughness. Typical use cases include shaft turning, facing, and profiling operations in production machining environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIC830 grade with PVD-applied SumoTec TiAlN\/AlTiN\/TiN multilayer coating for extended tool life on steel and stainless steel\u003c\/li\u003e\n  \u003cli\u003eSM chip breaker geometry supports both finishing and medium machining chip control\u003c\/li\u003e\n  \u003cli\u003e90-degree square insert shape (S) with negative side clearance for rigid, stable cutting\u003c\/li\u003e\n  \u003cli\u003e0.031-inch (0.80 mm) corner radius balances surface finish quality with edge strength\u003c\/li\u003e\n  \u003cli\u003eCompatible with ISO P, M, S, and H workpiece material groups\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 3.00 mm (0.118 inch) for controlled material removal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in ISCAR ChamTurn toolholders accepting SC45MT-style square inserts with ANSI and ISO size code 100508.

Use the correct torque wrench and clamping screw specified by the toolholder manufacturer when seating the insert; do not overtighten. Inspect the insert pocket and clamping components for wear or debris before seating a new insert. Verify insert orientation for right-hand cutting direction before resuming operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SC45MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: S - Square, 90 Degree Included Angle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC830\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN \/ AlTiN \/ TiN (SumoTec PVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: SM (Finishing and Medium Machining)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.52 mm \/ 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Width\u003c\/strong\u003e: 9.52 mm \/ 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5.00 mm \/ 0.197 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.80 mm \/ 0.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 4.50 mm \/ 0.177 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.00 mm \/ 0.118 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Super Alloys (S), Hardened Materials (H)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: SC45MT100508\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: SC45MT 100508-SM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: ChamTurn\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Size Code\u003c\/strong\u003e: 100508\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 3308175\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51742809063730,"sku":"3308175","price":223.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d87211c48b901db420630f618951c74.jpg?v=1788839523","url":"https:\/\/voomisupply.com\/products\/iscar-3308175-sc45mt100508-sm-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
