It carries the NG3M450K designation within the Top Notch series and is coated via a PVD process for wear resistance. The insert delivers a 4.5 mm cutting width, a maximum depth of cut of 3.81 mm, and a positive rake angle of 10 degrees, making it well suited for consistent chip control in medium to semi-finish grooving applications. The KC730 grade falls within the C2, C3, and C4 material grades, targeting a range of steel and alloy machining applications. Machinists and CNC operators in production and job-shop environments typically specify this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for right-hand grooving operations on lathes and turning centers using Top Notch compatible toolholders. With a 0.32 mm corner radius, a 55-degree included angle, and a K-style chip breaker, it is suited for controlled chip evacuation during groove profiling. The metric insert size designation is 3M450, and the measurement type is metric. It is a single-use, non-multi-use insert without a full radius nose geometry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e4.5 mm cutting width with a maximum depth of cut of 3.81 mm\u003c\/li\u003e\n\u003cli\u003eKC730 grade solid carbide with PVD-applied TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 10 degrees for reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eK-style chip breaker for controlled chip formation in grooving operations\u003c\/li\u003e\n\u003cli\u003e0.32 mm corner radius and 55-degree included angle for precise groove geometry\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation for standard OD grooving setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series compatible grooving toolholders that accept NG-style inserts.

Power down and lock out the machine before seating or replacing the insert. Use the appropriate torx or hex key to secure the insert clamp to the manufacturer-specified procedure without over-torquing the clamping screw. Inspect the insert pocket and clamping components for wear or debris before seating a new insert.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3M450\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 4.5 mm (0.1772 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 3.81 mm (0.1500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 3.00 mm to 4.00 mm (0.1500 to 0.2000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.32 mm (0.0126 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\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 Grade\u003c\/strong\u003e: C2, C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\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\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-use Tool\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\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: 0.0198 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\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: 1152082\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727226044722,"sku":"1152082","price":257.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9208e3dad90238c773e0e9d3f46f2d43.jpg?v=1788674982","url":"https:\/\/voomisupply.com\/products\/kennametal-1152082-grooving-insert-ng3m450k-kc730-4-5mm","provider":"Voomi Supply","version":"1.0","type":"link"}
