The insert features a solid carbide substrate with an Al2O3 (aluminum oxide) CVD coating, which provides thermal resistance and wear protection during continuous and interrupted cuts. The 55-degree diamond shape (ANSI code DNMG432EEX, ISO code DNMG150408N-EX) delivers a sharp, stable cutting edge geometry with a neutral hand orientation. The EEX chip breaker and positive rake angle of 16 degrees promote controlled chip flow, making this insert well suited for medium to finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use in metalworking environments where consistent dimensional accuracy and surface finish are required. The AC630M grade is targeted at stainless steel (secondary workpiece material code M) applications, though the CVD Al2O3 coating also supports use in general-purpose steel turning. Typical install scenarios include production turning on CNC lathes, turning centers, and manual engine lathes equipped with appropriate DNMG-compatible toolholders. A licensed machinist or CNC operator installs this insert as a direct replacement in the DN series toolholder system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD Al2O3 coating for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e55-degree diamond insert shape with neutral hand orientation for flexible toolholder mounting\u003c\/li\u003e\n  \u003cli\u003eEEX chip breaker geometry with 16-degree positive rake for controlled chip evacuation\u003c\/li\u003e\n  \u003cli\u003eClamp and pin insert holding method for rigid, repeatable seating in the toolholder pocket\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO 13399 standards; dual-coded DNMG432EEX and DNMG150408N-EX for cross-reference\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0313 inches for finish-cut applications requiring low surface roughness\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in DNMG-style indexable turning toolholders that accept a 55-degree diamond insert with a 0.5-inch inscribed circle, clamp and pin holding method, and clearance code N.

Ensure the toolholder pocket is clean and free of chips or debris before seating the insert. Use the appropriate torx or clamp screw driver specified by the toolholder manufacturer to secure the clamp; do not overtighten. Inspect the insert edge and chip breaker for damage before resuming cuts.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: DNMG432EEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: DNMG150408N-EX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (55 degrees)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC630M\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Al2O3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: EEX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 16 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.612 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.2031 inches\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 Holding Method\u003c\/strong\u003e: Clamp and Pin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: DN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\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: SUMITOMO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 19PW170\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51749190730034,"sku":"19PW170","price":269.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a909ac867311a14aea1e46d9caeb6ad6.jpg?v=1788903027","url":"https:\/\/voomisupply.com\/products\/sumitomo-19pw170-turning-insert-dnmg432eex-ac630m-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
