Built from solid carbide and CVD-coated with a TiCN, Al2O3, and TiN multilayer system, this insert delivers high thermal resistance and wear protection during demanding turning operations. The ANSI designation is CNMG542EM TT9215, grade TT9215. It features a 5\/8-inch inscribed circle, a 0.031-inch corner radius, and an 80-degree diamond shape. Licensed machinists and CNC operators install this insert in clamp-style toolholders for high-accuracy turning passes on difficult-to-machine materials.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for turning stainless steel, super-alloys, and titanium, where heat and work-hardening are primary concerns. The EM chip breaker geometry and negative rake design help control chip formation and cutting forces in these demanding material categories. It is suited for both roughing and semi-finishing passes where a maximum depth of cut up to 0.250 inches is required. The neutral hand orientation makes it compatible with a wide range of standard CNMG-format toolholders used in production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD-applied TiCN, Al2O3, and TiN multilayer coating for high wear and heat resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) with neutral hand orientation\u003c\/li\u003e\n  \u003cli\u003eEM chip breaker geometry optimized for stainless steel, super-alloys, and titanium\u003c\/li\u003e\n  \u003cli\u003eNegative rake and 0-degree relief angle (Clearance Code N) for stable clamped cutting\u003c\/li\u003e\n  \u003cli\u003eFour usable cutting edges per insert for extended tool life and lower cost per edge\u003c\/li\u003e\n  \u003cli\u003eMaximum depth of cut of 0.250 inches; 0.031-inch corner radius for controlled surface finish\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement for CNMG542 series clamp-style turning insert toolholders accepting a 5\/8-inch inscribed circle, 1\/4-inch thick diamond insert.

Power down and lock out the machine spindle before changing or indexing any insert. Use the appropriate torque wrench and clamp screw specified by the toolholder manufacturer when seating the insert to prevent insert rocking or premature failure. Inspect the insert pocket and clamp for wear or debris before seating a new cutting edge.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CNMG542EMTT9215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160608EM TT9215\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT9215\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: TiCN, Al2O3, TiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees, Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.250 inches\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: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees (Clearance Code N)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTolerance Code\u003c\/strong\u003e: M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EM\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Super-alloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 542\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\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: INGERSOLL CUTTING TOOLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5521726\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":51972356604210,"sku":"5521726","price":45.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e92dd7bce49d62c0ddd85148bb6cdd6a_cd1ad4f9-3f26-482b-8a63-1710b9732a43.jpg?v=1789966801","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-5521726-turning-insert-cnmg542em","provider":"Voomi Supply","version":"1.0","type":"link"}
