Manufactured to ANSI and ISO 13399 standards, this insert carries the CCMT21.51 ANSI size code and ISO code CCMT060204. It features an 80-degree diamond (rhombic) insert shape, a 1\/4 inch inscribed circle, and a 1\/64 inch corner radius. The uncoated PCD grade DA1000 delivers moderate wear resistance combined with toughness, making it well suited for stable cuts in aluminum and other non-ferrous workpieces. Licensed machinists, CNC operators, and tool-and-die professionals use this insert in turning centers and manual lathes.\u003c\/p\u003e\n\u003cp\u003eThis insert is intended for use on non-ferrous metals, including aluminum and similar soft, abrasive materials where PCD tooling outperforms carbide. The neutral hand orientation makes it compatible with standard CCMT-style toolholders that accept pin and screw holding methods. The LD chip breaker geometry supports light to moderate depth-of-cut applications. It is sold individually and is appropriate for production turning operations in both job-shop and high-volume manufacturing environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePCD (polycrystalline diamond) insert material for non-ferrous and aluminum machining\u003c\/li\u003e\n  \u003cli\u003eGrade DA1000 — balanced moderate wear resistance and toughness\u003c\/li\u003e\n  \u003cli\u003eCCMT insert style with positive rake and positive side clearance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond (rhombic) shape with 1\/64 inch corner radius\u003c\/li\u003e\n  \u003cli\u003eLD chip breaker geometry for controlled chip formation\u003c\/li\u003e\n  \u003cli\u003eCompliant with ANSI and ISO 13399 standards; dual-coded CCMT21.51 and CCMT060204\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CCMT-style toolholders that accept pin and screw insert retention.

Power down and lock out the machine spindle before seating or replacing the insert. Use the appropriate torx or hex key to tighten the clamping screw to the toolholder manufacturer specification — do not overtighten, as PCD inserts are brittle and susceptible to edge chipping under side load. Inspect the toolholder pocket for debris or damage before seating the insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\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\u003eANSI Insert Code\u003c\/strong\u003e: CCMT21.51\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT060204\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.2500 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 Length\u003c\/strong\u003e: 0.1142 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch (0.0709 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: LD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated (Bright)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Pin and Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal (ISO Code N)\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: 0.06 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 16HQEEW\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51744629489970,"sku":"16HQEEW","price":87.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/49d10bff4c08ff12051beb001bf0c955_e7d8d287-fd21-44d9-acf9-13a5c0351b02.jpg?v=1788859206","url":"https:\/\/voomisupply.com\/products\/sumitomo-16hqeew-pcd-turning-insert-ccmt21-51-1-4-in-ic","provider":"Voomi Supply","version":"1.0","type":"link"}
