Designed for screw-on toolholders, this neutral-hand insert features an 80-degree diamond shape with a positive rake angle of 5 degrees and a honed cutting edge. At 9.67 mm in length with a 3\/8-inch inscribed circle and a 1\/32-inch corner radius, it delivers controlled chip formation through the LF chip breaker geometry. Two cutting edges are available per insert. Machinists and CNC operators working in high-production turning environments rely on this insert for consistent tool life on difficult-to-machine materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning, facing, and boring operations on steel, stainless steel, superalloys, and titanium. The TiAlN PVD coating provides thermal resistance and wear protection suited to these primary workpiece material groups. The LF chip breaker geometry promotes efficient chip evacuation during light-to-moderate depth-of-cut passes, with a maximum depth of cut of 0.0492 inch (1.25 mm). It is well-suited for both roughing approaches near that limit and precision finishing passes where edge integrity is critical. The KC5010 grade is a Kennametal designation optimized for these ISO material groups.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTiAlN PVD coating for thermal and wear resistance on steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eLF chip breaker geometry for controlled chip evacuation during turning, facing, and boring\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with positive 5-degree rake for reduced cutting forces\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style for edge stability and consistent surface finish\u003c\/li\u003e\n  \u003cli\u003eScrew-on holding method compatible with standard CCMT toolholders\u003c\/li\u003e\n  \u003cli\u003eTwo usable cutting edges per insert for extended tool economy\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in screw-on CCMT-style toolholders accepting a 3\/8-inch inscribed circle insert.

Ensure the machine spindle is fully stopped and the toolholder is secure in the turret before seating or rotating the insert. Inspect the insert pocket for chips or debris before installation to ensure proper seating and avoid insert rocking. Rotate to the second cutting edge only after the first edge shows wear; do not reuse edges that show chipping or thermal cracking.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT3252LF\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\u003eChip Breaker\u003c\/strong\u003e: LF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degree)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\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\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 9.67 mm (0.3808 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 5\/32 inch (0.1563 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/32 inch (0.0313 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1732 inch (4.40 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.0492 inch (1.25 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\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\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\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: 0.0079 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 (Minimum Order Quantity: 5)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 1870986\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51727737291058,"sku":"1870986","price":213.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2ebc4fcd903c5cced3c9e1c586cc2b6a.jpg?v=1788681444","url":"https:\/\/voomisupply.com\/products\/kennametal-1870986-turning-insert-ccmt3252lf-kc5010","provider":"Voomi Supply","version":"1.0","type":"link"}
