It is a 55-degree diamond (rhombic) shaped insert designed for finishing and light machining operations on a CNC or manual lathe. The insert carries a neutral hand orientation, a positive rake angle of 5 degrees, a 7-degree relief angle, and a honed cutting edge style. With a 0.0039-inch corner radius and a maximum depth of cut of 0.0492 inches, it is optimized for close-tolerance, fine-surface-finish work rather than heavy stock removal. Two cutting edges are available per insert, and the screw-on holding method provides secure, repeatable seating in compatible toolholders.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations in both shop and production environments. Its KC730 grade targets steel, stainless steel, cast iron, and superalloys and titanium, offering high to moderate wear resistance with adequate toughness across those material families. Typical applications include finishing passes on precision components in aerospace, automotive, and general machining where consistent surface finish and dimensional accuracy are required. The LF chip breaker geometry is matched to light feeds and shallow depths of cut common in these finishing scenarios.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e55-degree diamond (DCGT) insert shape with positive rake and positive side clearance for low cutting forces\u003c\/li\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\u003eLF chip breaker geometry engineered for finishing and light machining chip control\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping during fine finishing passes\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method for rigid, repeatable positioning in toolholders\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert, reducing per-edge tooling cost\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in screw-on DCGT-style toolholders accepting a 1\/4-inch inscribed circle insert.

Use the appropriate Torx or hex key to torque the clamping screw per the toolholder manufacturer's recommendation — do not use impact drivers. Inspect the insert pocket and seating surfaces for chips or debris before installing a new insert, as contamination can affect edge height repeatability and surface finish. Verify correct insert orientation (neutral hand) relative to the toolholder before resuming cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCGT21502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCGT070201\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: D - Diamond (Rhombic) 55 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\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and 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: 7 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\u003eCorner Radius\u003c\/strong\u003e: 0.0039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2500 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 7.75 mm (0.6104 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\u003eInsert Width\u003c\/strong\u003e: 0.2500 inches (1\/4 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: 0.0492 inches (1.25 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\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, 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: 0.0029 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\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: 1161872\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755105517874,"sku":"1161872","price":203.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a6eedf3efa7c76edf2ae9e672f54d27c.jpg?v=1788951185","url":"https:\/\/voomisupply.com\/products\/kennametal-1161872-dcgt21-50lf-kc730-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
