Running in the Top Notch series, it carries the NGD4125K insert style with a KCU25 manufacturer grade and an AlTiN coating applied via PVD process. The insert delivers a cutting width of 3.18 mm (0.1252 inches) and a maximum depth of cut of 6.35 mm (0.2500 inches), making it well suited for moderate-depth grooving work. The K chip breaker geometry and a corner radius of 0.19 mm (0.0075 inches) help control chip flow in demanding interrupted and continuous cuts. Machinists and CNC tool setters working in job shops and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis insert is intended for use in external grooving applications on metalcutting lathes and turning centers where a right-hand cutting orientation is required. The Top Notch series platform uses a clamp-style insert holding method, which provides secure seating during high-feed and high-speed passes. It is appropriate for use on steel, alloy steel, and similar workpiece materials where carbide grades in the C2 and C6 material grade range are recommended. The metric measurement type and 4125 insert size designation align with standard Top Notch toolholders configured for that seat size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction with AlTiN PVD coating for wear resistance and thermal stability\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width with maximum depth of cut range of 5.00 to 10.00 mm\u003c\/li\u003e\n\u003cli\u003eRight-hand insert orientation for standard external grooving setups\u003c\/li\u003e\n\u003cli\u003eK chip breaker geometry for controlled chip evacuation\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm for blending and radius grooving at tight tolerances\u003c\/li\u003e\n\u003cli\u003eClamp-style insert holding method for rigid, repeatable seating in Top Notch toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series clamping toolholders that accept insert seat size 4 and the NGD4125 insert style.

Power down and lock out the machine spindle before changing or indexing inserts. Use the appropriate torque-limiting screwdriver or clamp key specified for the Top Notch toolholder to seat the insert without over-clamping. Inspect the insert pocket and clamp for chips or debris before seating a new insert to ensure full and stable contact.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NGD\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: KCU25\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C2, C6\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: AlTiN\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: 3.18 mm (0.1252 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 6.35 mm (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 5.00 to 10.00 mm (0.2000 to 0.3000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Height\u003c\/strong\u003e: 11.51 mm (0.4530 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Width\u003c\/strong\u003e: 6.50 mm (0.256 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.19 mm (0.0075 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 4125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Seat Size\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFull Radius\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\u003ePackage Dimensions\u003c\/strong\u003e: 14.8 x 7.1 x 2.7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.055 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: 4109853\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51754335797554,"sku":"4109853","price":336.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/817f9f4d146307b3631d0addd8405e98_91e342da-d97a-44c8-8c51-2a14a594b457.jpg?v=1788944468","url":"https:\/\/voomisupply.com\/products\/kennametal-4109853-grooving-insert-kcu25-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
