The insert features a TiAlN coating applied via PVD process, delivering high wear resistance across a range of workpiece materials. It carries an 80-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and a 7-degree relief angle, producing clean surface finishes with reduced cutting forces. The 1\/64-inch corner radius and honed cutting edge style make this insert well suited for fine finishing passes where dimensional accuracy and surface quality are priorities. Licensed machinists and CNC operators are the primary installers of this insert.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for turning, facing, and boring operations on steel, stainless steel, cast iron, superalloys, titanium, and aluminum. The LF chip breaker geometry is optimized for finishing and light machining, providing reliable chip control at tighter depths of cut. The neutral hand orientation allows use in standard right-hand turning toolholders that accept CCGT-style screw-on inserts. Maximum depth of cut is 0.0845 inches. The KCU10 grade offers high to moderate wear resistance and toughness across ISO material groups P, M, K, N, S, and H, making it a versatile choice for shops running mixed-material production work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN coating via PVD process for high wear resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with positive rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry optimized for finishing and light machining operations\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style improves edge strength on fine finishing passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation fits standard CCGT screw-on toolholders\u003c\/li\u003e\n  \u003cli\u003e2 cutting edges per insert; screw-on holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on CCGT-style turning toolholders.

Use the appropriate torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque range for screw-on inserts. Inspect the insert pocket and seating surface for chips or debris before indexing to a fresh cutting edge. Do not run the insert beyond visible wear limits, as edge breakdown on finishing inserts can rapidly degrade workpiece surface finish and dimensional tolerances.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCGT2151\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCGT060204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCU10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN (PVD Process)\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\u003eIncluded Angle\u003c\/strong\u003e: 80 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: 5 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0845 inches\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\u003eNumber of Cutting 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\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing; Light Machining\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel; Stainless Steel; Superalloys and Titanium; Cast Iron; Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: 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: 0.003 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: 4045138\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727250194738,"sku":"4045138","price":194.79,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a7ece123d61c7330dd8f89c336742928.jpg?v=1788675404","url":"https:\/\/voomisupply.com\/products\/kennametal-4045138-turning-insert-ccgt2151lf-kcu10-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
