Manufactured to the HC210 grade and coated with titanium nitride (TiN) via a PVD process, this insert delivers improved wear resistance and extended tool life compared to uncoated carbide. It features a 90-degree square shape with a neutral hand orientation, a 0.5 inch inscribed circle, and a 1\/64 inch (0.0156 inch) corner radius. It belongs to the KENDEX series and is held in place by a clamp-style toolholder. Installation and use are appropriate for machinists and tooling technicians working in production or job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations on stainless steel, non-ferrous metals, and superalloys, corresponding to ISO workpiece material groups M, N, and S, with secondary suitability for cast iron (group K). The SPG421 style and positive rake geometry make it well-matched for finish and semi-finish turning passes where controlled chip formation and surface quality are priorities. The maximum depth of cut is 1.25 mm (0.0492 inches), confirming its role in lighter, precision-oriented cuts rather than heavy roughing. Typical applications include shaft turning, facing, and contour work on mid-size CNC turning centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHC210 solid carbide grade with TiN coating applied via PVD process for improved surface hardness and wear resistance\u003c\/li\u003e\n\u003cli\u003eSPG421 insert style with positive rake geometry for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation for flexible toolholder compatibility\u003c\/li\u003e\n\u003cli\u003eSquare insert shape (90-degree included angle) with 1\/64 inch corner radius for defined edge geometry\u003c\/li\u003e\n\u003cli\u003eClamp-style holding method compatible with standard SPG toolholders\u003c\/li\u003e\n\u003cli\u003eSuitable for ISO material groups M, N, S (primary) and K (secondary)\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style toolholders that accept SPG421 geometry inserts.

Power down and lock out the machine spindle before changing inserts. Seat the insert fully in the pocket and secure the clamp to the toolholder manufacturer's specified procedure before resuming cuts. Inspect the insert edge condition regularly; do not continue cutting with a chipped or worn edge, as this can damage the workpiece or toolholder.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPG421\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (S)\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\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: N (None)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: M, N, S (Stainless Steel, Non-Ferrous, Superalloys)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: K (Cast Iron)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HERTEL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000411\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51749693751602,"sku":"1000411","price":318.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/36693265c0ec9c0aaa99f591dcb88133.jpg?v=1788909297","url":"https:\/\/voomisupply.com\/products\/hertel-1000411-spg421-hc210-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
