It carries the KC730 grade with a PVD-applied TiN coating and a negative rake geometry, making it well suited for demanding cutting applications. The insert measures 0.125 inches thick with a corner radius of 0.0312 inches (0.79 mm) and an inscribed circle of 0.249 inches. Four cutting edges extend usable tool life per insert. Licensed machinists and CNC turning specialists install and index this insert as part of routine tooling maintenance on production turning operations.\u003c\/p\u003e\u003cp\u003eThis insert is intended for profiling and turning operations on steel, stainless steel, superalloys, and titanium, corresponding to ISO work material codes P, M, and S. Material grades P10, P20, M10, M20, S10, and S20 are covered. It is a left-hand insert and is held in the toolholder by a screw clamping method. Typical applications include contour turning, shoulder turning, and form profiling on short-run and production parts in job shop and manufacturing environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC730 carbide grade with PVD TiN coating for extended wear resistance on steel and superalloys\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry with 0 degree relief angle for stable cutting edge on interrupted and continuous cuts\u003c\/li\u003e\n\u003cli\u003eFour usable cutting edges per insert to reduce per-edge tooling cost\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0312 inches (0.79 mm) for fine profiling detail\u003c\/li\u003e\n\u003cli\u003eScrew-clamp insert holding method for secure, repeatable indexing\u003c\/li\u003e\n\u003cli\u003eParallelogram insert shape with 55 degree included angle for profiling clearance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders accepting the NPL52 insert style.

Use the appropriate Torx or hex key to seat the clamping screw to the toolholder manufacturer's specified torque range — do not overtighten, as this can fracture the carbide body. Verify insert seating and orientation before resuming the cut. Handling carbide inserts with bare hands can introduce contaminants to seating surfaces; use clean gloves or a soft cloth.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPL\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 52\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC730\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grades\u003c\/strong\u003e: P10, P20, M10, M20, S10, S20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\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\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\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: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1250 inches (3.18 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.3770 inches (9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Length\u003c\/strong\u003e: 0.3770 inches (11.60 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth (Inscribed Circle)\u003c\/strong\u003e: 0.2490 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (0.79 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1257 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: KCGX110308L15\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0098 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1163218\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51730830524722,"sku":"1163218","price":187.56,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/53e60e8e1d1b66205ccc2f88f8632d05.jpg?v=1788723543","url":"https:\/\/voomisupply.com\/products\/kennametal-1163218-npl52-kc730-profiling-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
