Carrying the TT8125B manufacturer grade, this insert features a CVD-applied multilayer coating of TiCN, Al2O3, and TiN, delivering wear resistance and thermal barrier performance in continuous and interrupted cut applications. The 80-degree diamond insert shape (CNMG, Insert Shape Code C) provides two high-strength cutting edges per corner, yielding four usable cutting edges per insert. With a 0.635-inch insert length and a 5\/8-inch inscribed circle, it fits standard CNMG 542-series toolholders. The MT chip breaker geometry is suited for medium turning conditions on steel.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for CNC lathes and turning centers in production environments where steel is the primary workpiece material. The neutral hand orientation allows use in both right-hand and left-hand toolholder configurations. The 0.031-inch corner radius balances surface finish capability with edge strength, making it appropriate for medium-depth roughing and semi-finishing passes. A maximum depth of cut of 0.256 inches supports moderate material removal rates. Machinists and CNC operators in job shops, OEM manufacturing, and tool-and-die environments will encounter this insert as a standard-replacement or upgrade option for steel turning operations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCVD multilayer coating: TiCN, Al2O3, and TiN for extended tool life on steel\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape provides strong cutting edge geometry with four usable edges\u003c\/li\u003e\n  \u003cli\u003eMT chip breaker optimized for medium turning conditions\u003c\/li\u003e\n  \u003cli\u003eNeutral hand insert fits both right-hand and left-hand CNMG 542-series toolholders\u003c\/li\u003e\n  \u003cli\u003e0.031-inch corner radius suitable for medium-roughing and semi-finishing passes\u003c\/li\u003e\n  \u003cli\u003eClamp-style insert holding method compatible with standard CNMG toolholder clamping systems\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for CNMG 542-series toolholders.

Inspect the toolholder pocket and clamping screw for wear or damage before seating the insert. Use the appropriate torx or hex key to torque the clamp screw per the toolholder manufacturer specification. Rotate or index to the next cutting edge only after confirming the previous edge has reached the end of its serviceable life.\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\u003eSeries\u003c\/strong\u003e: CNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 542\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CNMG160608MT TT8125B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: TT8125B\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Layers\u003c\/strong\u003e: TiCN, Al2O3, Titanium Nitride (TiN)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (80 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Negative\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: 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: MT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.635 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.250 inches (1\/4 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.625 inches (5\/8 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: 0.256 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 Holding Method\u003c\/strong\u003e: Clamp\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material Code\u003c\/strong\u003e: P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWiper Edge\u003c\/strong\u003e: No\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: 6212684\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"INGERSOLL CUTTING TOOLS","offers":[{"title":"Default Title","offer_id":52013420642610,"sku":"6212684","price":46.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8d7b25e10dbb4af2c53b952cfcfba0db_da9a7d02-3c83-488d-97c4-81e058711ffc.jpg?v=1790006188","url":"https:\/\/voomisupply.com\/products\/ingersoll-cutting-tools-6212684-turning-insert-cnmg542mt","provider":"Voomi Supply","version":"1.0","type":"link"}
