This single-tipped, screw-on insert features an 80-degree diamond (rhombic) shape with a positive rake angle and positive side clearance, delivering sharp cutting-edge geometry optimized for high-precision material removal. With a 0.25-inch inscribed circle, a 6.45 mm insert length, and a 0.0079-inch corner radius, it is engineered for fine-tolerance turning, facing, and boring operations. Licensed machinists and CNC tooling technicians specify this insert for demanding production environments where tool life and surface finish consistency are critical.\u003c\/p\u003e\n\u003cp\u003eThis PCD insert is suited for high-speed turning, facing, and boring of non-ferrous metals and select superalloys on CNC lathes and turning centers. Its flat-top chip breaker geometry and uncoated bright finish make it particularly effective in aluminum, copper, and other non-ferrous workpiece materials where built-up edge must be minimized. The KD1400 grade provides high wear resistance in both N-class (aluminum and non-ferrous) and S-class (special and superalloy) material categories, making it versatile across multiple workpiece families in production turning environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePolycrystalline diamond (PCD) insert material for high wear resistance in non-ferrous and superalloy turning\u003c\/li\u003e\n  \u003cli\u003eCPGW21505FST industry standard number; conforms to both ANSI and ISO insert geometry standards\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) insert shape with positive rake and positive side clearance for sharp, low-force cutting\u003c\/li\u003e\n  \u003cli\u003eFlat-top chip breaker design with sharp cutting edge style for clean chip formation in ductile materials\u003c\/li\u003e\n  \u003cli\u003eScrew-on insert holding method for secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n  \u003cli\u003eSingle tipped; multi-use application covering turning, facing, and boring operations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on style toolholders accepting CPGW-geometry inserts with a 0.1102-inch (2.80 mm) hole diameter and a 0.25-inch inscribed circle.

Power down and de-energize the machine tool completely before indexing or replacing any insert. Use the appropriate torque wrench and screw specified by the toolholder manufacturer when securing the screw-on insert to avoid over-torquing the clamping screw. PCD inserts are extremely hard and brittle at the cutting edge — handle carefully to prevent chipping prior to installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Diamond (PCD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KD1400\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CPGW21505\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CPGW060202\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CPGW21505FST\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\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: 0.1102 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\u003eRake Angle\u003c\/strong\u003e: 0 degrees (Positive Rake)\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\u003eChip Breaker\u003c\/strong\u003e: Flat Top\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Sharp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal; Special and Super Alloys\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: N05; N15\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\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: 3659968\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51746225258802,"sku":"3659968","price":185.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/654578cbe757c4d2bcfdc21a4b5320fd.jpg?v=1788867330","url":"https:\/\/voomisupply.com\/products\/kennametal-3659968-pcd-turning-insert-cpgw21505fst-kd1400","provider":"Voomi Supply","version":"1.0","type":"link"}
