It carries an HC335 grade designation and features a multilayer CVD coating of TiC, TiCN, and TiN applied over a solid carbide substrate. The insert has a 0.5 inch inscribed circle, a 1\/32 inch (0.0310 inch) corner radius, and a square shape with a 90-degree included angle. It holds a neutral hand orientation, making it compatible with right-hand or left-hand toolholders. Machinists and CNC operators install this insert for precision turning applications where coating durability and edge retention are required.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning ferrous metals classified under ISO material group P (carbon and alloy steels) and group M (stainless steels), covering a broad range of general-purpose turning, facing, and light profiling work. It fits the KENDEX series toolholder system and is held in place via a clamp-style holding method. The positive rake geometry reduces cutting forces and heat generation, which is advantageous when machining tougher alloys or when minimizing deflection on slender workpieces. The maximum depth of cut is 1.25 mm (0.0492 inch), making it appropriate for finishing and semi-finishing passes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eHC335 grade solid carbide substrate with multilayer CVD coating: TiC, TiCN, and TiN\u003c\/li\u003e\n  \u003cli\u003eSquare insert shape with 90-degree included angle and neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003e0.5 inch inscribed circle with 1\/32 inch corner radius for controlled edge geometry\u003c\/li\u003e\n  \u003cli\u003ePositive rake geometry reduces cutting forces during steel and stainless turning\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method compatible with KENDEX series toolholders\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inch) for finishing and semi-finishing applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with KENDEX series clamp-style toolholders accepting SPG-style inserts with a 0.5 inch inscribed circle, 1\/8 inch thickness, and clearance code P.

Power down or place the machine in an e-stop state before changing inserts, and use proper insert-handling tools to avoid contact with cutting edges. Ensure the toolholder pocket and clamp are free of chips and debris before seating the insert. Verify clamp torque per the toolholder manufacturer specifications before resuming cutting operations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPG422\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC335\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: TiC, TiCN, TiN (CVD Process)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (90-degree included angle)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches (0.5000 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches decimal)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0310 inches decimal)\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\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\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\u003eHolding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Steels)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: M (Stainless Steels)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: HERTEL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1000395\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752131887410,"sku":"1000395","price":319.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b131cf9b073350af5f60a8588b61bc4b.jpg?v=1788926073","url":"https:\/\/voomisupply.com\/products\/hertel-1000395-turning-insert-spg422-hc335-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
