The insert features a Physical Vapor Deposition (PVD) titanium nitride (TiN) coating that delivers high wear resistance across a range of workpiece materials. With a 60-degree triangular shape, positive rake angle of 5 degrees, and a honed cutting edge, the 1162892 is engineered for finish to medium machining operations. Three cutting edges per insert extend tool life. The inscribed circle measures 0.25 inches, insert length is 0.4331 inches (11 millimeters), and the corner radius is 0.0313 inches (1\/32 inch). Mounting is by screw-on method, consistent with standard toolholders using the TPGM insert style.\u003c\/p\u003e\n\u003cp\u003eThis insert is suited for turning, facing, and boring operations in both small and large shop environments. Its KC730 grade targets steel (P), stainless steel (M), cast iron (K), superalloys, and titanium workpiece materials, covering a broad range of production turning applications. The medium chip breaker profile handles moderate feed rates and depths of cut up to 0.0492 inches (1.25 millimeters). The neutral hand orientation allows use in standard TPGM-compatible screw-on toolholders. Typical users include CNC machinists, toolroom operators, and production turning technicians who require consistent, repeatable edge performance across material types.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eKC730 grade with PVD TiN coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n  \u003cli\u003eTPGM geometry: 60-degree triangle, positive rake, 11-degree relief angle, positive side clearance\u003c\/li\u003e\n  \u003cli\u003eThree usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces micro-chipping in interrupted and continuous cuts\u003c\/li\u003e\n  \u003cli\u003eMedium chip breaker profile suited for moderate feed and depth-of-cut conditions\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method compatible with standard TPGM-style toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on TPGM-style turning toolholders conforming to ANSI insert code TPGM2152 and ISO insert code TPGM110208.

Power down and lock out the machine spindle before seating or replacing inserts. Use the manufacturer-specified torx or hex key to secure the clamping screw to the recommended seat; do not overtighten, as carbide inserts are brittle and can fracture under excess clamping force. Inspect the insert pocket and seating surface for chips or debris before mounting a new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TPGM2152\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TPGM110208\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle (60 degrees included angle)\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: KC730\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiN (Titanium Nitride)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4331 inches (11.00 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches (1\/32 inch)\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: Medium Machining (Common)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches (2.80 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 millimeters)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0031 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1162892\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51744542294322,"sku":"1162892","price":214.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/39685f3b4f61b23fa160d835930c3a05.jpg?v=1788857840","url":"https:\/\/voomisupply.com\/products\/kennametal-1162892-turning-insert-tpgm21-52-kc730-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
