Manufactured to grade KC850 with a CVD-applied multilayer coating of TiC, TiCN, and TiN, this insert delivers wear resistance and thermal stability across a wide range of workpiece materials. The insert carries an NGP style designation, a left-hand cutting orientation, and a 3.18 mm cutting width with a maximum depth of cut of 2.79 mm. It is intended for installation by machinists and tool-room technicians working on production turning applications.\u003c\/p\u003e\u003cp\u003eThis insert is suited for external grooving, face grooving, and light parting operations on steel and cast iron workpieces in both production and job-shop environments. The KC850 grade with CVD multilayer coating is optimized for continuous and light interrupted cuts at moderate-to-high cutting speeds. Insert size 2125 fits Top Notch series toolholders designed for that insert geometry. The positive rake angle of 5 degrees reduces cutting forces, making it appropriate for medium-duty turning setups where surface finish and dimensional consistency are priorities.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide substrate, KC850 grade, material grades C5 and C6\u003c\/li\u003e\n\u003cli\u003eCVD multilayer TiC, TiCN, and TiN coating for wear and heat resistance\u003c\/li\u003e\n\u003cli\u003eLeft-hand cutting orientation, NGP insert style\u003c\/li\u003e\n\u003cli\u003e3.18 mm cutting width with a maximum depth of cut of 2.79 mm\u003c\/li\u003e\n\u003cli\u003ePositive rake angle of 5 degrees to reduce cutting forces\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.19 mm for controlled edge definition\u003c\/li\u003e\n\u003cli\u003eTop Notch series compatibility for secure, repeatable seating\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in Top Notch series toolholders that accept the NGP 2125 insert size.

Ensure the machine spindle is fully stopped and the turret is indexed to a safe position before removing or seating the insert. Use the appropriate torx or hex key specified for the Top Notch toolholder clamp to secure the insert without over-torquing the clamping screw. Inspect the toolholder pocket for chips or debris before seating the new insert to ensure proper contact and accurate tool offset.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NGP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: 2125\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Left 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: KC850\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C5, C6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: TiC, TiCN, TiN\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: 2.79 mm (0.1098 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut Range\u003c\/strong\u003e: 2.00 mm to 3.00 mm (0.1000 to 0.1500 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\u003eInsert Height\u003c\/strong\u003e: 0.2190 inches\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\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\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\u003eWeight\u003c\/strong\u003e: 0.0071 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: 1114931\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743923011890,"sku":"1114931","price":273.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/690339e2c5d5077066b89495343e395d.jpg?v=1788851357","url":"https:\/\/voomisupply.com\/products\/kennametal-1114931-ngp2125-kc850-grooving-insert-left-hand","provider":"Voomi Supply","version":"1.0","type":"link"}
