This triangle-shaped insert carries the HC335 manufacturer grade and features a three-layer CVD coating — TiC, TiCN, and TiN — applied in sequence to improve wear resistance and extend cutting life. It has a neutral hand orientation, a 3\/64-inch (0.0470-inch) corner radius, and a 60-degree included angle. The inscribed circle measures 1\/2 inch (0.5000 inch), and insert thickness is 3\/16 inch (0.1875 inch). Insert length is 22 mm (0.8661 inch). It is part of the KENDEX series and is installed by machining professionals in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on ferrous metals, including steels and stainless steels, corresponding to ISO material categories P and M. It uses a clamp-style holding method (Clearance Code P, Tolerance Code G) and a positive rake geometry. Maximum depth of cut is 1.25 mm (0.0492 inch), making it appropriate for finishing and light-to-medium roughing passes. It fits standard TPG-style toolholders used in general-purpose turning. The chip breaker designation is N (no chip breaker), which is typical for finishing grades where edge sharpness is the priority.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eHC335 grade solid carbide with CVD-applied TiC, TiCN, and TiN multilayer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eTPG433 style with triangle insert shape (60-degree included angle) and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003ePositive rake geometry suited for finishing and light-to-medium cutting passes\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding with Tolerance Code G for consistent seating and dimensional accuracy\u003c\/li\u003e\n\u003cli\u003eRated for ISO P and M workpiece materials — carbon steels and stainless steels\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inch) for controlled finishing operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard TPG-style clamp toolholders accepting a 1\/2-inch inscribed circle triangle insert.

Power down and lock out the machine spindle before changing inserts. Use the appropriate torque wrench and clamping hardware specified by the toolholder manufacturer — do not overtighten the clamp screw, as this can fracture the carbide substrate. Inspect the toolholder pocket and clamp for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPG433\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60-degree included angle)\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\/Finish\u003c\/strong\u003e: TiC, TiCN, TiN (CVD process)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 3\/16 inch (0.1875 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 22 mm (0.8661 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 3\/64 inch (0.0470 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inch)\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: 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\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\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: 0.5 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: 1000691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51752345665842,"sku":"1000691","price":394.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f37a196d8341f6fc90cac179909e277.jpg?v=1788927605","url":"https:\/\/voomisupply.com\/products\/hertel-1000691-turning-insert-tpg433-hc335-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
