It carries the ANSI code TNMG331 and ISO code TNMG160404, identifying a triangular insert with a neutral hand orientation, a 0.40 mm (0.0157 inch) corner radius, and six usable cutting edges. The CVD coating and ACP15K grade deliver high wear resistance across a range of workpiece materials, making this insert a reliable choice for production turning environments where tool life and consistent surface finish are priorities.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel, stainless steel, and cast iron in both roughing and semi-finishing applications. The WM+ chip breaker geometry supports moderate feed rates and depths of cut up to 4.00 mm (0.1575 inches), helping control chip formation across varying cutting conditions. It is intended for use by machinists and CNC operators in job shops, production facilities, and maintenance machining environments. The negative side clearance (N clearance code, M tolerance code) is consistent with standard TNMG toolholders that use clamp, lever lock, pin, or screw holding methods.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD-coated ACP15K carbide grade for high wear resistance on steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert for extended tool life and lower per-edge cost\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker supports controlled chip evacuation at moderate feeds and depths\u003c\/li\u003e\n\u003cli\u003e0.40 mm corner radius for a balance of edge strength and surface finish capability\u003c\/li\u003e\n\u003cli\u003eCompatible with clamp, lever lock, pin, and screw-style TNMG toolholders\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits a wide range of turning toolholder setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TNMG331 (ISO: TNMG160404) indexable insert seats using clamp, lever lock, pin, or screw holding methods.

Power down and lock out the machine before indexing or replacing inserts. Seat the insert fully and evenly in the pocket before tightening the clamping mechanism to the toolholder manufacturer's specified method. Inspect the insert pocket and seating surface for chips or debris before each insert index to avoid seating errors that can cause premature edge failure.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG331\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG160404\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: TNMG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: T - Triangle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACP15K\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.40 mm (0.0157 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 4.76 mm (0.1874 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 9.53 mm (0.3752 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1512 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 4.00 mm (0.1575 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Lever Lock, Pin, Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel (P), Stainless Steel (M), Cast Iron (K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75283614\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51754410737970,"sku":"75283614","price":164.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f40d6d1193f820428b34edd4d167006_a81a5cb8-14f8-40f6-9e69-a024f2c37132.jpg?v=1788945135","url":"https:\/\/voomisupply.com\/products\/accupro-75283614-tnmg331-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
