It features a TiAlN coating applied via PVD process, which provides heat resistance and extended tool life during interrupted and continuous cuts. The insert delivers a 4.8 mm cutting width, a maximum depth of cut of 3.81 mm, and a 0.57 mm corner radius, making it suited for medium to fine grooving work in steel, stainless steel, and cast iron. A positive rake angle of 10 degrees reduces cutting forces and promotes chip evacuation. This insert is installed by machinists and CNC tooling specialists in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThe 1817618 is intended for use in external grooving, face grooving, and light parting applications on turning equipment. Its KC5025 grade and K chip breaker geometry are well matched to applications requiring consistent chip control and surface finish. The right-hand orientation suits conventional lathe setups where the tool feeds from right to left. Typical use cases include groove-for-seal applications, undercuts, and step features on turned components in both high-volume production and precision one-off work. The insert style is NG with an included angle of 55 degrees and a 3-degree lead angle.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with TiAlN coating via PVD process for heat and wear resistance\u003c\/li\u003e\n  \u003cli\u003eKC5025 manufacturer grade suited for grooving in steel, stainless, and cast iron\u003c\/li\u003e\n  \u003cli\u003e4.8 mm cutting width with a maximum depth of cut of 3.81 mm\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle of 10 degrees reduces cutting forces and aids chip flow\u003c\/li\u003e\n  \u003cli\u003eK chip breaker geometry promotes controlled chip formation in medium to fine feeds\u003c\/li\u003e\n  \u003cli\u003eRight-hand insert orientation for standard lathe tool holder setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in Top Notch series tool holders that accept NG-style grooving inserts.

Always power down and lock out the machine spindle before changing inserts. Seat the insert fully into the Top Notch holder pocket and verify clamping torque per the holder manufacturer specification before resuming cuts. Inspect the insert seating surface and holder pocket for chips or debris prior to installation to prevent insert rocking or premature fracture.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5025\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 4.80 mm (0.1890 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: 0.57 mm (0.0225 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Height\u003c\/strong\u003e: 0.3440 inches\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: 10 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 3 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 3189\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0243 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23242105\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1817618\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51737514967346,"sku":"1817618","price":255.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a674567cdbb17757fecdafd5041c3f5.jpg?v=1788789570","url":"https:\/\/voomisupply.com\/products\/kennametal-1817618-grooving-insert-ng3189k-kc5025","provider":"Voomi Supply","version":"1.0","type":"link"}
