It features a 55-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and an 11-degree relief angle, making it suited for finishing and light machining operations. The insert measures 0.6104 inches in length with a 0.25-inch inscribed circle and a 0.0039-inch corner radius. With two cutting edges and a screw-on holding method, this insert is installed by machinists and CNC tooling technicians on turning, facing, boring, back turning, and back boring applications.\u003c\/p\u003e\u003cp\u003eThis insert is designed for use on steel, stainless steel, and superalloys and titanium as primary workpiece materials, with secondary suitability for stainless steel and high-temperature alloys. The KC730 grade delivers high to moderate wear resistance combined with adequate toughness across these material categories. It is well suited for production turning on CNC lathes and machining centers where consistent surface finish and close tolerances are required. The LF chip breaker geometry supports controlled chip formation during light-pass finishing cuts with a maximum depth of cut of 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\u003e55-degree diamond insert shape with positive rake and positive side clearance for light, efficient cutting\u003c\/li\u003e\n\u003cli\u003eLF chip breaker optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003eTwo usable cutting edges per insert for extended tooling value\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method with ANSI code DPGT21502 and ISO code DPGT070201\u003c\/li\u003e\n\u003cli\u003eMulti-use capability across turning, facing, boring, back turning, and back boring\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-on OEM-style replacement turning insert conforming to ANSI standard DPGT21502 and ISO standard DPGT070201, compatible with toolholders accepting DPGT-style inserts with a 0.1102-inch hole diameter and 0.25-inch inscribed circle.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified CNC machinists or tooling technicians. Power down and lock out the machine before indexing or replacing inserts. Use the appropriate torx or hex key to secure the clamping screw to the toolholder without overtightening, which can crack the carbide substrate. Verify insert seating and edge orientation against the toolholder pocket before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DPGT21502\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DPGT070201\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.6104 inches (7.75 mm)\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: 0.0039 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1102 inches\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\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake\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\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, 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: 0.0031 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: 1161933\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51748265197874,"sku":"1161933","price":197.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9c32a17025959203e33f65a83dcf5f5.jpg?v=1788891390","url":"https:\/\/voomisupply.com\/products\/kennametal-1161933-turning-insert-dpgt21-50lf-kc730","provider":"Voomi Supply","version":"1.0","type":"link"}
