Designated DCMT32.52LF under the ANSI system and DCMT11T308 under ISO, this insert features a 55-degree diamond (rhombic) shape with a positive rake angle of 5 degrees and a 7-degree relief angle. The KC730 grade carries a PVD-applied TiN coating optimized for high wear-resistance across a range of workpiece materials. With an LF chip breaker geometry, the insert is engineered for finishing and light machining passes where surface finish and edge control are critical. It is installed by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, boring, back turning, and back boring operations. Primary workpiece materials include steel, stainless steel, and cast iron, with secondary suitability for superalloys and titanium. The KC730 grade delivers high to moderate wear-resistance and toughness across these material groups, making it a versatile choice for shops running varied material types without frequent grade changes. The neutral hand orientation supports use in standard right-hand toolholders configured for DCMT-style screw-on insert seating.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eANSI code DCMT3252 \/ ISO code DCMT11T308 for cross-reference compatibility\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 optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003e55-degree diamond insert shape with positive rake and positive side clearance for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eScrew-on insert holding method ensures secure, repeatable seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003eTwo cutting edges per insert; honed cutting edge style for consistent edge integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DCMT-style screw-on turning toolholders conforming to ANSI and ISO standards for the 3252 \/ 11T308 insert size designation. Consult toolholder manufacturer specifications to confirm seat and clamp compatibility before installation.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the machine powered down and the spindle locked before seating or replacing the insert. Use a torx or hex key as specified by the toolholder manufacturer to secure the clamping screw — do not over-torque, as carbide inserts are brittle and can crack under excessive clamping force. Inspect the insert pocket and seating surfaces for chips or debris before seating the new insert. Follow applicable shop safety procedures and machine tool manufacturer guidelines when resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: DCMT3252\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: DCMT11T308\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\u003eChip Breaker\u003c\/strong\u003e: LF\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: 3\/8 inches (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inches (0.0313 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 11.63 mm (0.9156 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inches (0.1563 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\u003eRelief Angle\u003c\/strong\u003e: 7 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\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 Material\u003c\/strong\u003e: Solid Carbide\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium\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\u003eMulti-Use Applications\u003c\/strong\u003e: Turning, Facing, Boring, Back Turning, Back Boring\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: 0.0108 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: 1161929\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51750032310578,"sku":"1161929","price":170.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/923f20dc8f5e02186c55f57c8e446244.jpg?v=1788913258","url":"https:\/\/voomisupply.com\/products\/kennametal-1161929-dcmt32-52lf-kc730-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
