This uncoated insert carries the HT10 manufacturer grade and features a 90-degree square shape with a 1\/2-inch inscribed circle and a 1\/32-inch (0.0312 inch) corner radius. The neutral hand orientation makes it suitable for both left- and right-hand toolholders. Clamped into a compatible toolholder, it delivers a positive rake geometry and an 11-degree relief angle, reducing cutting forces and heat buildup during finishing and semi-finishing passes. It is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis insert belongs to the HERTEL KENDEX series and is intended for turning applications on non-ferrous metals and stainless or alloyed steels. Primary workpiece material classifications are N and S; secondary classifications are K and M, covering cast iron and medium-carbon alloy steels. The maximum depth of cut is 0.0492 inch (1.25 mm), making this insert best suited for finishing and light semi-finishing operations rather than heavy roughing. It is sold individually with a minimum order quantity of 10 units per order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction, uncoated, material grade C2 for sharp-edge retention on non-ferrous and alloyed workpieces\u003c\/li\u003e\n  \u003cli\u003eSPMR422 insert style with positive rake and 11-degree relief angle to reduce cutting forces\u003c\/li\u003e\n  \u003cli\u003e1\/2-inch inscribed circle and 1\/8-inch insert thickness for rigid seating in standard SPMR toolholders\u003c\/li\u003e\n  \u003cli\u003e1\/32-inch corner radius for controlled surface finish on finishing passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand — fits both left-hand and right-hand toolholder configurations\u003c\/li\u003e\n  \u003cli\u003eClamp-style holding method with tolerance code M and clearance code P for consistent indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in SPMR-style clamp-type toolholders that accept a 1\/2-inch inscribed circle square insert.

Use the correct torque for the clamp screw per the toolholder manufacturer specifications — do not overtighten, as this can fracture the carbide body. Inspect the pocket seat and clamp for wear or debris before seating a new insert. Follow applicable shop safety and machine-guarding standards during service.\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\u003eManufacturer Grade\u003c\/strong\u003e: HT10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Square (Shape Code S)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/2 inch (0.5000 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0312 inch)\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: N, S\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: K, M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 10\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: 1000407\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51732834484530,"sku":"1000407","price":275.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30455de239c962014500943eadb38a6e.jpg?v=1788747347","url":"https:\/\/voomisupply.com\/products\/hertel-1000407-spmr422-ht10-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
