It carries an 80-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and a positive side clearance, making it suited for finishing and light machining operations. The insert measures 6.45 mm (0.2539 inches) in length with a 0.25-inch inscribed circle, a corner radius of 0.0079 inches (1\/128 inch), and an insert thickness of 0.0938 inches (3\/32 inch). The LF chip breaker is designed to manage chip flow during light cuts and finishing passes. Machinists and CNC operators working in job shops or production environments install these inserts on screw-on style toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is designed for turning, facing, and boring operations. Its KC730 grade targets steel (P), stainless steel (M), and cast iron (K) workpiece materials with a high-wear-resistance to moderate-toughness profile. Secondary applications include superalloys and titanium (S and M material codes). The maximum depth of cut is 1.25 mm (0.0492 inches), keeping the insert in its intended finishing range. It conforms to ANSI insert code CPGT21505 and ISO insert code CPGT060202, allowing straightforward cross-referencing to compatible toolholders from various manufacturers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with TiN PVD coating delivers high wear resistance across steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (CPGT) shape with positive rake and positive side clearance reduces cutting forces on finishing passes\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for finishing and light machining — maximum depth of cut 1.25 mm\u003c\/li\u003e\n\u003cli\u003eScrew-On (hole-type) holding method with 0.1142-inch hole diameter for secure, repeatable clamping\u003c\/li\u003e\n\u003cli\u003eDual cutting edges extend usable tool life per insert\u003c\/li\u003e\n\u003cli\u003eConforms to ANSI and ISO standards — ANSI CPGT21505, ISO CPGT060202\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-on style replacement turning insert conforming to ANSI insert code CPGT21505 and ISO insert code CPGT060202, compatible with toolholders engineered for CPGT-geometry inserts with a 0.25-inch inscribed circle and screw-lock mounting.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before changing inserts. Seat the insert fully in the pocket and torque the clamping screw according to the toolholder manufacturer's specification — do not estimate or exceed the recommended value. Inspect the insert pocket for wear, chips, or debris before seating a new insert, as a damaged pocket will affect cutting performance and surface finish.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPGT21505\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPGT060202\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\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)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive, 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 6.45 mm (0.2539 inches)\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: 0.0079 inches (1\/128 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1142 inches (2.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\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: 0.0022 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: 1161906\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51753229779250,"sku":"1161906","price":194.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63de5c22ca287d86c30fe8e8fbc22d2e.jpg?v=1788934126","url":"https:\/\/voomisupply.com\/products\/kennametal-1161906-turning-insert-kc730-tin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
