It carries the ISO designation TNMG160408 and is manufactured in grade ACP25M with a CVD coating for extended wear resistance across a broad range of workpiece materials. The insert features a neutral hand orientation, a WM+ chip breaker geometry, and six usable cutting edges, delivering consistent performance per edge and lower cost per part. Corner radius measures 0.0315 inches (0.80 mm) and maximum depth of cut reaches 0.1575 inches (4.00 mm).\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning steel, stainless steel, and cast iron in production machining environments. The ACP25M grade spans high wear-resistance through high toughness for steel (P-code), and high wear-resistance through moderate wear-resistance and toughness for stainless steel (M-code) and cast iron (K-code). It fits toolholders accepting TNMG-style inserts with negative side clearance and is appropriate for light to medium roughing and semi-finishing passes. Machinists in job shops and production facilities running ferrous materials will find this insert a reliable choice for general-purpose turning work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCVD coating on ACP25M carbide grade for high wear-resistance across steel, stainless steel, and cast iron\u003c\/li\u003e\n\u003cli\u003eWM+ chip breaker geometry supports a wide range of feeds and depths on ferrous materials\u003c\/li\u003e\n\u003cli\u003eSix cutting edges per insert reduce tooling cost per part\u003c\/li\u003e\n\u003cli\u003eNeutral hand orientation fits standard TNMG toolholders with clamp, lever lock, pin, or screw holding methods\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0315 inches (0.80 mm) balances surface finish and edge strength\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.1575 inches (4.00 mm) suitable for semi-finishing to moderate roughing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for TNMG332 (ISO: TNMG160408) style toolholders accepting negative-rake triangular inserts with a hole diameter of 0.1512 inches and an inscribed circle of 0.3752 inches.

Use the appropriate torx or hex key specified by the toolholder manufacturer to seat and secure the insert without overtightening. Inspect the toolholder pocket and clamping components for wear or debris before seating a new insert. Verify depth-of-cut and feed-rate parameters against the grade characteristics before resuming cuts.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: TNMG332\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: TNMG160408\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: ACP25M\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: WM+\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 60 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Negative\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\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1874 inches (4.76 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.3752 inches (9.53 mm)\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: 0.1575 inches (4.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 6\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\u003eInsert Holding Method\u003c\/strong\u003e: Clamp, Lever Lock, Pin, Screw\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: 75475822\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742150787378,"sku":"75475822","price":181.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0f40d6d1193f820428b34edd4d167006_00c0ec34-b0ad-4923-9259-791bd551c3b9.jpg?v=1788835592","url":"https:\/\/voomisupply.com\/products\/accupro-75475822-tnmg332-carbide-turning-insert","provider":"Voomi Supply","version":"1.0","type":"link"}
