Built to the DNMX insert style with a 55-degree diamond shape, this insert features a neutral hand orientation and a negative rake angle of 0 degrees. The inscribed circle measures 0.5 inches, insert length is 0.2441 inches, and the corner radius is 1\/64 inch. Carrying the DA1000 material grade designation, the insert arrives bright and uncoated, preserving the sharp PCD cutting edge for direct application. It is suitable for CNC turning centers and manual lathes operated by skilled machinists working to tight tolerances on aluminum, copper, brass, and similar non-ferrous workpiece materials.\u003c\/p\u003e\u003cp\u003eThis insert is used in turning operations on non-ferrous metals where surface finish quality and dimensional accuracy are critical. The LD chip breaker geometry helps manage chip flow in continuous and semi-continuous cuts. The pin and screw holding method provides rigid insert seating, making it appropriate for production turning environments where insert repeatability matters. It conforms to ANSI and ISO 13399 standards, fitting into compatible toolholders designed for the DNMX insert family and Series D designation. Typical users include CNC machinists, tool and die shops, and precision parts manufacturers running high-speed finishing passes on non-ferrous components.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePolycrystalline diamond (PCD) cutting material for non-ferrous machining applications\u003c\/li\u003e\n\u003cli\u003eDNMX insert style with 55-degree diamond shape and neutral hand orientation\u003c\/li\u003e\n\u003cli\u003eLD chip breaker geometry for controlled chip flow during turning operations\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish preserves PCD edge integrity out of the box\u003c\/li\u003e\n\u003cli\u003ePin and screw holding method for secure, repeatable insert positioning\u003c\/li\u003e\n\u003cli\u003eCompliant with ANSI and ISO 13399 insert standards\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in DNMX-style toolholders that accept Series D inserts with a pin and screw holding method.

Use the appropriate torx or hex key to loosen the clamping screw or pin per the toolholder manufacturer's torque procedure. Handle PCD inserts with care to avoid chipping the cutting edge during seating. Confirm insert orientation and hand designation match the toolholder before resuming operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: DNMX\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 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\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 0 degrees\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: 0.2441 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: 1\/64 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Polycrystalline Diamond (PCD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: DA1000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHolding Method\u003c\/strong\u003e: Pin and Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: D\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: NF-DNMX150404N-LD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI and ISO 13399\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: SUMITOMO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 16HQWHH\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51750690423090,"sku":"16HQWHH","price":131.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1387a1cbc85e69f037e155e448d18e22_df9be747-1ee5-42ab-854b-12d2d12cc1a9.jpg?v=1788918501","url":"https:\/\/voomisupply.com\/products\/sumitomo-16hqwhh-turning-insert-pcd-neutral-dnmx431ld","provider":"Voomi Supply","version":"1.0","type":"link"}
