It carries the ANSI insert code TPU321 and ISO code TPU160304, with a triangular shape (60-degree included angle) offering three usable cutting edges. The insert features a multilayer CVD coating of TiC, TiCN, and TiN over a KC850 carbide grade substrate, delivering moderate wear resistance combined with toughness across a broad range of workpiece materials. It has a neutral hand orientation and a positive rake and side clearance geometry with a flat-top chip breaker and honed cutting edge style.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations in both light and moderate material removal applications. The KC850 grade targets steel and stainless steel as primary workpiece materials (ISO P and M classifications), with strong capability in cast iron (K) and special or super alloys (S) as well. It is appropriate for production machining environments where consistent edge life across varying material grades is required. The flat-top chip breaker geometry handles continuous and semi-interrupted cuts without a chip groove, making it a straightforward choice for general-purpose turning in job shops and manufacturing facilities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTriangular TPU insert shape with 60-degree included angle and three cutting edges per insert\u003c\/li\u003e\n\u003cli\u003eKC850 grade with multilayer CVD TiC, TiCN, and TiN coating for wear resistance and toughness balance\u003c\/li\u003e\n\u003cli\u003ePositive rake and positive side clearance (clearance code P) for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eFlat-top chip breaker with honed cutting edge for stable performance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation compatible with standard TPU-style toolholders using clamp-style insert holding\u003c\/li\u003e\n\u003cli\u003eMulti-use application covering turning, facing, and boring in a single insert geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in KENDEX-series TPU-style toolholders that accept TPU321 inserts per ANSI and ISO standards.

Verify the toolholder pocket is clean and free of debris before seating the insert to avoid rocking or uneven contact. Clamp torque should follow the toolholder manufacturer specification for the clamp screw size used. Do not exceed the maximum depth of cut of 0.0492 inches (1.25 mm) specified for this insert geometry.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPU321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPU160304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: KENDEX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (T), 60-degree included angle\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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiC, TiCN, TiN (Multilayer CVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Rake)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Special and Super Alloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0116 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: KENNAMETAL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 1162775\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51738884702514,"sku":"1162775","price":171.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b1dba449e62cb7d04d36d3f89dedfba5.jpg?v=1788806167","url":"https:\/\/voomisupply.com\/products\/kennametal-1162775-tpu321-kc850-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
