It features a physical vapor deposition (PVD) TiAlN coating engineered for high wear resistance across steel, stainless steel, and cast iron applications. The insert has an 80-degree trigon (W-shape) geometry with a positive rake angle of 5 degrees and a 7-degree relief angle, giving it a clean shearing action suited to finishing and light machining passes. With an inscribed circle of 0.25 inches and a corner radius of 0.0156 inches, it delivers tight tolerances on finish cuts. Machinists and CNC operators install this insert in compatible screw-on toolholders for turning, facing, and boring operations.\u003c\/p\u003e\u003cp\u003eThis insert is designed for finishing and light machining cycles on steel, stainless steel, superalloys, and titanium, corresponding to material codes P, M, K, N, and S. Its positive side clearance and honed cutting edge style reduce cutting forces, making it well suited to thin-wall parts, close-tolerance diameters, and materials sensitive to heat buildup. The maximum depth of cut is 1.25 mm (0.0492 inches), placing it firmly in the finishing envelope. Three cutting edges per insert extend tool life and reduce per-edge cost in high-cycle production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eKC5010 grade with PVD TiAlN coating for high wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003e80-degree trigon insert shape (WCMT) with positive rake and positive side clearance\u003c\/li\u003e\n\u003cli\u003eThree usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003cli\u003eLF chip breaker geometry optimized for finishing and light machining operations\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style reduces micro-chipping on difficult-to-machine alloys\u003c\/li\u003e\n\u003cli\u003eScrew-on holding method provides rigid, repeatable seating in the toolholder pocket\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a screw-on turning insert conforming to ANSI designation WCMT2151 and ISO designation WCMT110204, fitting standard WCMT-style toolholders that accept a 0.25-inch inscribed circle insert with screw-on retention.

Use the correct torx or hex key to the toolholder manufacturer's recommended seating procedure when tightening the clamping screw — do not over-torque, as carbide inserts are brittle and will crack under excessive clamp load. Inspect the pocket seat and clamping screw threads for chips or debris before seating a new insert. Dispose of used inserts according to applicable shop safety protocols for sharp carbide waste.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: WCMT2151\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: WCMT110204\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: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\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 Shape\u003c\/strong\u003e: W - Trigon 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0156 inches (1\/64 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 4.34 mm (0.3418 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches (3\/32 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 2.80 mm (0.1102 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 1.25 mm (0.0492 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Finishing and Light Machining\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw-On\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: C3, C4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\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: 1871041\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51755881333042,"sku":"1871041","price":184.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a29d71f2480ec107bc452e0fd434b71d.jpg?v=1788961021","url":"https:\/\/voomisupply.com\/products\/kennametal-1871041-turning-insert-wcmt2151lf-kc5010-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
