Designated by ANSI code TPGH321 and ISO code TPGH160304, it features a 60-degree triangular shape, a 3\/8 inch (0.3750 inch) inscribed circle, a 1\/64 inch (0.0156 inch) corner radius, and an insert thickness of 1\/8 inch (0.1250 inch). The LF chip breaker geometry and honed cutting edge make this insert well-suited for controlled, consistent chip formation in finishing passes. It is held by screw clamping and offers three usable cutting edges per insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for turning, facing, and boring applications on CNC turning equipment in both production and job-shop environments. It is rated for primary workpiece materials including steel (P), stainless steel (M), cast iron (K), aluminum and non-ferrous materials (N), superalloys and titanium (S), and hardened materials (H). The KCU10 grade delivers high to moderate wear resistance with appropriate toughness across these material groups. Typical users include CNC machinists and toolroom technicians working with a screw-on insert toolholder system compatible with TPGH321 geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTiAlN PVD coating provides strong oxidation resistance and wear life in steel and stainless steel cutting\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003eTriangular insert shape with 11-degree relief angle and positive rake for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eThree cutting edges per insert for extended tooling economy\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.2163 inches supports light-to-moderate material removal\u003c\/li\u003e\n\u003cli\u003eCompliant with both ANSI and ISO insert standards for broad toolholder compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on style toolholders accepting TPGH321 (ANSI) or TPGH160304 (ISO) triangular inserts with a 0.1310 inch hole diameter.

Use the appropriate Torx or socket-head screw driver to seat the insert securely against the toolholder pocket without overtightening. Inspect the pocket seating surface for chips or debris before installing a new edge. Verify tool offset and perform a test cut before returning the machine to full production feed rates.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPGH321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPGH160304\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (AlTiN)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Triangle (60 degrees included angle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 16.50 mm (0.6496 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\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1310 inches (3.33 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2163 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Aluminum and Non-Ferrous, Superalloys and Titanium, Hardened Materials\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\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: 0.01 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: 4053344\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51740654108978,"sku":"4053344","price":205.72,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4dc82209f1324f1622776f36aa24dbe5.jpg?v=1788826496","url":"https:\/\/voomisupply.com\/products\/kennametal-4053344-turning-insert-tpgh321-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
