The insert features a PVD-applied TiN coating under the KC730 grade, which delivers high wear resistance combined with moderate toughness across a range of workpiece materials. The triangular (T) insert shape provides three cutting edges and mounts via screw-on holding method. It has a 3\/8 inch inscribed circle, a 1\/64 inch corner radius (0.0156 inches), and a 7-degree relief angle with positive rake geometry. Insert length is 0.6496 inches (16.50 mm) and thickness is 5\/32 inches (0.1563 inches).\u003c\/p\u003e\u003cp\u003eThis insert is suited for finishing passes in turning, facing, and boring operations on CNC and manual lathes used in job shops, production machining, and maintenance environments. It is particularly effective when machining steel (P-grade), stainless steel (M-grade), and cast iron (K-grade) components. The HP chip breaker geometry is optimized for finishing cuts with a maximum depth of cut of 0.0492 inches (1.25 mm). The positive rake angle of 15 degrees reduces cutting forces, making it a practical choice for light-duty finishing on both rigid and moderately compliant setups. Machinists and CNC programmers working to tight tolerances will recognize the G tolerance classification, which ensures consistent insert-to-insert dimensional accuracy.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\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\u003eHP chip breaker geometry engineered for finishing operations at shallow depths of cut\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (15 degrees) and honed cutting edge reduce cutting forces and improve surface finish\u003c\/li\u003e\n\u003cli\u003eThree cutting edges per insert with screw-on holding for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eG tolerance classification provides consistent dimensional accuracy across inserts\u003c\/li\u003e\n\u003cli\u003eMeets ANSI and ISO standards; compatible with standard TCGT-style screw-on toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard TCGT screw-on insert toolholders accepting a 3\/8 inch inscribed circle triangular insert.

Before indexing or replacing the insert, power down and lock out the machine spindle per applicable shop lockout\/tagout procedures. Seat the insert fully on the toolholder pocket and tighten the screw-on fastener to the toolholder manufacturer's specified torque. Inspect the cutting edge and seat for debris or damage before resuming cuts. Handle carbide inserts with care to avoid chipping the honed edge prior to use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TCGT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TCGT16T304\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 (PVD process)\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: T - Triangle\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: 5\/32 inches (0.1563 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\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 15 degrees (positive)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: HP (Finishing)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inches (1.25 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: G\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\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\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0097 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: 1162005\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51731994345778,"sku":"1162005","price":253.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c782b6c9f4e2d2d1aea2315092e8195.jpg?v=1788737794","url":"https:\/\/voomisupply.com\/products\/kennametal-1162005-tcgt3251hp-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
