It features a 60-degree triangular shape with a positive rake geometry and a neutral hand orientation. The insert carries a multi-layer CVD coating of TiC, TiCN, and TiN under manufacturer grade HC335, which supports wear resistance and thermal stability during interrupted and continuous turning operations. The inscribed circle measures 3\/8 inches and the corner radius is 1\/64 inches. Insert length is 0.6496 inches (16.50 mm) and insert thickness is 1\/8 inches. It is held by a clamp-style toolholder and belongs to the KENDEX series.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning applications on P-class primary workpiece materials (carbon and alloy steels) and M-class secondary workpiece materials (stainless steels). Material grades C5 and C6 indicate suitability for finishing to semi-finishing passes on steels where controlled chip formation is required. The maximum depth of cut is 0.0492 inches (1.25 mm), making it appropriate for light to medium finishing operations. The R chip breaker geometry is designed to manage chip flow in these material types. Machinists and CNC setup technicians working in production turning environments are the primary installers of this insert.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate with CVD-applied TiC, TiCN, and TiN multi-layer coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eTPMR321 insert style with 60-degree triangular shape and positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard clamp-style TPMR toolholders\u003c\/li\u003e\n\u003cli\u003eCorner radius of 1\/64 inches (0.0156 inches) for tight-tolerance finishing cuts\u003c\/li\u003e\n\u003cli\u003eR chip breaker geometry optimized for steel and stainless steel turning\u003c\/li\u003e\n\u003cli\u003eKENDEX series with clearance code P and tolerance code M for consistent seating and repeatability\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in clamp-style TPMR-series toolholders accepting a 3\/8-inch inscribed circle triangular insert.

Before changing inserts, ensure the machine spindle is fully stopped and the toolholder is secured or removed from the turret per shop lockout\/tagout procedures. Use the appropriate torque wrench and clamp hardware specified by the toolholder manufacturer when seating the insert. Inspect the insert pocket and clamp for wear or debris before seating a new insert to ensure proper contact and prevent premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPMR321\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 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 (CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6496 inches (16.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/8 inches (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inches (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\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\u003eChip Breaker\u003c\/strong\u003e: R\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: M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: P (Carbon and Alloy 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\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: 1000696\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HERTEL","offers":[{"title":"Default Title","offer_id":51750025593138,"sku":"1000696","price":269.44,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c1fda56852b6c3eb48c818d31e9e9f21.jpg?v=1788913195","url":"https:\/\/voomisupply.com\/products\/hertel-1000696-turning-insert-tpmr321-hc335-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
