The insert carries a dual PVD coating of TiAlN and TiN, which extends tool life at elevated cutting temperatures. It features a rectangular shape with a positive rake geometry and a honed cutting edge, promoting clean chip formation and reduced cutting forces. With four usable cutting edges and a right-hand orientation, it delivers consistent performance across multiple indexing cycles. This insert is used by machinists and CNC tooling specialists in precision milling operations on ferrous and exotic workpiece materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling applications involving steel, stainless steel, superalloys, and titanium, corresponding to ISO material groups P, M, and S. It is compatible with the Mill 4-12 cutter series and is held in place by a screw-clamp method. The GE chip breaker geometry supports controlled chip evacuation during high-feed or high-speed passes. Typical installation scenarios include face milling, shoulder milling, and slot milling on CNC machining centers in production or job-shop environments. The ANSI and ISO code for this insert is LNGQ120608ERGEKT4.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with PVD-applied TiAlN and TiN dual coating for thermal and wear resistance\u003c\/li\u003e\n  \u003cli\u003eFour cutting edges on a single-sided, right-hand insert maximizes cost per edge\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle with honed cutting edge reduces cutting forces on difficult materials\u003c\/li\u003e\n  \u003cli\u003eGE chip breaker geometry designed for steel, stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eScrew-held mounting method ensures secure seating and repeatable indexing\u003c\/li\u003e\n  \u003cli\u003eConforms to ANSI and ISO standards under code LNGQ120608ERGEKT4\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCompatible with the Kennametal Mill 4-12 cutter series.

Always power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torx or hex key to the cutter body manufacturer's specified seating procedure when securing the clamp screw  -  do not overtighten or use impact tools. Inspect the insert pocket and seating surface for debris or damage before each insert is seated to ensure proper contact and runout control.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: LNGQ\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: KCSM40\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Rectangle\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: TiAlN and TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\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 Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: GE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0.00 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.2500 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5270 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0312 inches (1\/32 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.5270 inches (13.39 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 0.5118 inches (13.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1929 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 120608\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI\/ISO Code\u003c\/strong\u003e: LNGQ120608ERGEKT4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: Mill 4-12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys and Titanium\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: 0.0192 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 6525755\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KENNAMETAL","offers":[{"title":"Default Title","offer_id":51743442698546,"sku":"6525755","price":347.67,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f50e98a5909674845dcbe2f07b97bc11_57724d47-eedc-4cd6-a74f-c2e67febd111.jpg?v=1788847088","url":"https:\/\/voomisupply.com\/products\/kennametal-6525755-milling-insert-kcsm40-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
