Manufactured to the KENDEX series standard, this insert carries a TiN (titanium nitride) coating applied via PVD process, which improves surface hardness and wear resistance during continuous and interrupted cuts. The triangular 60-degree geometry with a neutral hand orientation makes it a versatile choice for general-purpose turning. It features a 1\/4-inch inscribed circle and a 1\/64-inch corner radius, with an insert length of 11 mm (0.4331 inches) and a thickness of 1\/8 inch (0.1250 inches).\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning operations on stainless steel, non-ferrous metals, and high-temperature alloys, corresponding to workpiece material groups M, N, and S as primary, and K as secondary. The positive rake geometry and clamp-style holding method make it appropriate for finishing and light roughing passes where controlled chip formation and dimensional accuracy are priorities. It is sold individually but carries a minimum order quantity of 10 units, making it suitable for shop-stock replenishment in production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with TiN coating via PVD process for extended tool life\u003c\/li\u003e\n\u003cli\u003eTPG221 style with 60-degree triangular geometry and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003e1\/4-inch inscribed circle with 1\/64-inch corner radius for precision turning\u003c\/li\u003e\n\u003cli\u003ePositive rake angle for reduced cutting forces on compatible workpiece materials\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for secure, repeatable seating in the toolholder\u003c\/li\u003e\n\u003cli\u003eKENDEX series designation for compatibility with corresponding toolholders and insert pockets\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TPG221-style insert seats in KENDEX series toolholders.

Use the appropriate torx or hex key to secure the clamp to the manufacturer-recommended feel without over-torquing, which can crack the carbide. Inspect the insert pocket and clamp for wear or debris before seating a new insert. Follow your machine tool manufacturer guidelines and applicable shop safety procedures when handling sharp carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPG221\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 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: HC210\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0160 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11 mm (0.4331 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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\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: G\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: M, N, S\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 1001198\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51735396548914,"sku":"1001198","price":221.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c6c530b7f9582985b69c1d00000aaca0.jpg?v=1788772265","url":"https:\/\/voomisupply.com\/products\/hertel-1001198-tpg221-hc210-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
