It carries the NPR132F insert style designation and is manufactured to the KNGX150408R20 ISO code. The grade KC5010 substrate features an AlTiN coating applied via PVD process, delivering wear resistance and thermal stability during high-speed cutting operations. The insert has a negative rake angle of 10 degrees, a 55-degree included angle, and a 0.80 mm corner radius, making it well suited to profiling contours and general turning passes where edge sharpness and finish quality matter. Licensed machinists and CNC tooling technicians are the primary installers of this insert.\u003c\/p\u003e\u003cp\u003eThis insert is intended for profiling and turning applications across a wide range of workpiece materials including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It covers ISO material grades P10, P20, M10, M20, K05, K10, K15, K20, N10, N20, S10, S20, and H10. Typical install scenarios include finish and semi-finish turning on Swiss-style lathes, gang tooling setups, and standard CNC turning centers where the Top Notch screw-clamping system is in use. The right-hand cutting orientation suits conventional tool post and turret configurations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5010 grade carbide substrate with AlTiN PVD coating for extended tool life on ferrous and difficult-to-machine materials\u003c\/li\u003e\n\u003cli\u003eNPR132F style with KNGX150408R20 ISO designation for precise tool library matching\u003c\/li\u003e\n\u003cli\u003e4 usable cutting edges maximize cost-per-edge value\u003c\/li\u003e\n\u003cli\u003e0.80 mm corner radius balances surface finish quality with edge strength during profiling passes\u003c\/li\u003e\n\u003cli\u003eNegative rake geometry with 0-degree relief angle suits screw-clamp Top Notch toolholders\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.1663 inches supports both roughing profiles and finishing contours\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with Top Notch series screw-clamp toolholders accepting NPR132F style inserts. Also cross-referenced to the KNGX150408R20 ISO standard insert designation. Confirm toolholder pocket geometry and screw torque specification with the toolholder documentation before use.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a machinist or CNC tooling technician. Power down and lock out the spindle before changing inserts. Seat the insert fully into the pocket and tighten the clamping screw to the torque value specified in the Top Notch toolholder documentation — do not estimate or substitute torque values. Inspect the pocket seat for chips or debris before seating a fresh edge, as contamination under the insert face will alter depth-of-cut accuracy and can fracture the carbide.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: NPR132F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: KNGX150408R20\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KC5010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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\u003eShape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3730 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.4990 inches (12.70 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Length\u003c\/strong\u003e: 0.4990 inches (15.44 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.1663 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 55 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees (Negative)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: Common\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Top Notch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Material Grades\u003c\/strong\u003e: P10, P20, M10, M20, K05, K10, K15, K20, N10, N20, S10, S20, H10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplications\u003c\/strong\u003e: Profiling, Turning\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.022 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 1849251\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51736166531378,"sku":"1849251","price":238.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5d8dd37d370db75dc94fc447f3aa064e.jpg?v=1788776297","url":"https:\/\/voomisupply.com\/products\/kennametal-1849251-npr132f-kc5010-carbide-profiling-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
