It carries the TPCG321 insert style designation and is manufactured in grade KC5010, a micrograin carbide substrate with a PVD-applied TiAlN coating for improved wear resistance and thermal stability at elevated cutting speeds. The insert features a 60-degree included angle in a triangular shape, a corner radius of 0.015 inches (1\/64 inch), an inscribed circle of 0.375 inches (3\/8 inch), and a thickness of 0.127 inches (1\/8 inch). The 11-degree relief angle and left-hand orientation make it suited for specific bore geometry requirements in ferrous and non-ferrous machining.\u003c\/p\u003e\u003cp\u003eThis insert is used in internal boring applications on CNC turning centers, manual lathes, and dedicated boring machines in industrial manufacturing environments. The left-hand configuration makes it appropriate for right-to-left tool travel or specific spindle orientations. It is typically installed by machinists and CNC operators in job shops, production machining facilities, and aerospace or automotive component manufacturing cells where tight bore tolerances are required. The TiAlN coating extends tool life in dry or minimal-lubrication cutting conditions.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide substrate for high edge integrity and fracture resistance\u003c\/li\u003e\n\u003cli\u003ePVD TiAlN coating provides heat resistance and extended wear life in dry cutting\u003c\/li\u003e\n\u003cli\u003eTPCG321 insert style with 60-degree triangle shape and 11-degree relief angle\u003c\/li\u003e\n\u003cli\u003eLeft-hand insert orientation for specific boring bar and toolholder configurations\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.015 inches balances surface finish quality with edge strength\u003c\/li\u003e\n\u003cli\u003eManufacturer grade KC5010 suited for general-purpose and finishing boring operations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in TPCG-style boring bar toolholders and insert seats that accept a 321-size triangular insert with a 0.130-inch hole diameter and left-hand orientation.

Power down and lock out the machine spindle before changing inserts. Use the correct torque driver or insert clamp hardware specified by the toolholder manufacturer — do not overtighten or substitute fasteners. Inspect the insert seat and clamp for debris or wear before seating the new insert to ensure proper support and repeatability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TPCG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 321\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.127 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.130 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1937630\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51732883931442,"sku":"1937630","price":221.92,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c3fdf93eff4c3f9a00c0ad7aa63bc5f6.jpg?v=1788748019","url":"https:\/\/voomisupply.com\/products\/kennametal-1937630-tpcg321-kc5010-boring-insert-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
