Manufactured to the SPMR422 style with a 90-degree square shape, this insert features a CVD-applied multilayer coating of TiC, TiCN, and TiN in the HC335 manufacturer grade. The 0.5 inch inscribed circle and 0.0312 inch (1\/32 inch) corner radius suit a wide range of finish and semi-finish turning cuts. The insert uses a clamp-style holding method and is rated for a maximum depth of cut of 0.0492 inch (1.25 mm). It is installed and changed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning steel and stainless steel workpiece materials, corresponding to ISO material groups P (steel) and M (stainless steel), and carries material grades C5 and C6. The KENDEX series geometry with a positive rake angle and R-style chip breaker supports controlled chip evacuation during turning. Typical applications include shaft turning, facing, and contour operations on ferrous materials in both production and repair machining contexts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multilayer coating in HC335 grade\u003c\/li\u003e\n  \u003cli\u003eSPMR422 style, 90-degree square insert shape with positive rake geometry\u003c\/li\u003e\n  \u003cli\u003e0.5 inch inscribed circle and 0.125 inch insert thickness for rigid clamping\u003c\/li\u003e\n  \u003cli\u003e0.0312 inch corner radius suitable for finish and semi-finish turning passes\u003c\/li\u003e\n  \u003cli\u003eR-style chip breaker for controlled chip formation on P and M workpiece materials\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method compatible with standard SPMR toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in toolholders that accept SPMR-style inserts with a 0.5 inch inscribed circle.

Always power down and lock out the machine spindle before changing inserts. Seat the insert fully against the toolholder pocket and torque the clamp screw according to the toolholder manufacturer's specifications. Inspect the insert seat and clamp for wear or debris before installation to ensure proper seating and repeatability.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: SPMR422\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (90 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: HC335\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5000 inch (1\/2 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inch (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1250 inch (1\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: M (Stainless Steel)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\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: 1000397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51737581257010,"sku":"1000397","price":340.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ee3ce93ea8199b2e7946e5f543cb8520.jpg?v=1788790796","url":"https:\/\/voomisupply.com\/products\/hertel-1000397-turning-insert-spmr422-hc335-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
