Manufactured to the NG3094K insert style in the Top Notch series, it carries the KT315 manufacturer grade with a PVD-applied multilayer TiN\/TiCN\/TiN coating for improved wear resistance and surface finish on the workpiece. The insert delivers a cutting width of 0.094 inches (2.39 mm) and a maximum depth of cut of 0.150 inches (3.81 mm). A positive rake angle of 10 degrees and the K chip breaker geometry help control chip flow in medium to fine finishing cuts. Installed by machinists and CNC tooling technicians, this insert is a single-use, non-multi-use tooling component intended for right-hand cutting orientation.\u003c\/p\u003e\u003cp\u003eThis insert is suited for grooving operations on steel, stainless steel, and cast iron workpieces where cermet grade tooling excels in producing tight tolerances and good surface finishes at moderate to high cutting speeds. The Top Notch series tooling system is a common platform on production turning equipment. The insert fits standard Top Notch series grooving tool holders that accept the NG insert style and size 3094. Typical applications include external groove machining, undercut profiles, and recessing in both production and job-shop turning environments. The material grades C3 and C7 indicate suitability for finishing and light interrupted cuts on ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKT315 cermet grade with PVD multilayer TiN\/TiCN\/TiN coating for extended tool life\u003c\/li\u003e\n\u003cli\u003eCutting width of 0.094 inches (2.39 mm) for precise groove sizing\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.150 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003ePositive rake angle (10 degrees) with K chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0075 inches (0.19 mm) for defined groove wall transitions\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting orientation; single-use insert design\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement insert for Top Notch series grooving and parting tool holders that accept the NG insert style in size 3094.

Use the appropriate torx or hex key specified by the tool holder manufacturer to seat the insert — do not overtighten the clamping screw. Inspect the insert pocket and clamping surfaces for chips or debris before seating. Replace the insert at the first sign of edge wear or chipping to prevent workpiece damage or tool holder damage.\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: 3094\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KT315\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiN \/ TiCN \/ TiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.094 inches (2.39 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.150 inches (3.81 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0075 inches (0.19 mm)\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\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\u003eFull Radius\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3 \/ C7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMeasurement Type\u003c\/strong\u003e: Metric\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\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 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: 1855578\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736793940274,"sku":"1855578","price":262.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0c59016e49195b3924864cd808a54a39.jpg?v=1788780450","url":"https:\/\/voomisupply.com\/products\/kennametal-1855578-grooving-insert-ng3094k-kt315-cermet","provider":"Voomi Supply","version":"1.0","type":"link"}
