It carries an 80-degree diamond (rhombic) shape with a neutral hand orientation and a positive rake angle of 5 degrees. The insert measures 9.67 mm (0.3808 inches) in length with a 3\/8-inch inscribed circle and a 1\/64-inch corner radius. The LF chip breaker is optimized for finishing and light machining operations, and the honed cutting edge style helps protect the edge during those light cuts. Licensed machinists and CNC turning specialists are the primary installers and users of this insert in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel, stainless steel, and cast iron workplates, as well as secondary applications in superalloys and titanium. The KC730 grade delivers high wear resistance balanced with moderate toughness, making it a reliable choice across P, M, and K workpiece material groups. The screw-on holding method provides secure clamping in compatible toolholders, and the insert delivers two usable cutting edges per unit. It is designed for light-depth finishing passes, with a maximum depth of cut of 1.25 mm (0.0492 inches).\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 grade with TiN PVD coating for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake and positive side clearance\u003c\/li\u003e\n\u003cli\u003eLF chip breaker optimized for finishing and light machining applications\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style for consistent performance on light cuts\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; screw-on holding method for secure toolholder engagement\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 1.25 mm (0.0492 inches) for fine finishing passes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on CPMT-style toolholders compatible with ANSI insert code CPMT3251 and ISO insert code CPMT09T304.

Power down and lock out the machine before seating or removing the insert. Use the correct screw torque driver recommended by the toolholder manufacturer to secure the screw-on insert without over-torquing the clamping screw. Inspect the pocket and seating surface for chips or debris before installing a new insert edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPMT3251\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPMT09T304\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\/Finish\u003c\/strong\u003e: TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF (Finishing \/ Light Machining)\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\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\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.67 mm (0.3808 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 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\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inches (4.40 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\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, 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: 0.022 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: 1161918\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727932686642,"sku":"1161918","price":213.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f3d9d33183048822780ab7f3d233328e.jpg?v=1788684699","url":"https:\/\/voomisupply.com\/products\/kennametal-1161918-turning-insert-cpmt32-51lf-kc730","provider":"Voomi Supply","version":"1.0","type":"link"}
