Manufactured to ANSI code CCMT21.51ENK and ISO code CCMT060204N-SK, this insert features an 80-degree diamond shape with a neutral hand orientation and a positive rake geometry. The CVD coating process applies the AC830P grade finish, optimizing wear resistance and thermal stability during metal removal. At 0.252 inches in length with a 1\/4-inch inscribed circle and a 1\/64-inch corner radius, this insert suits finish to semi-finish turning passes where dimensional consistency is critical. Installation is performed by licensed machinists or CNC tooling technicians using screw-style insert holding.\u003c\/p\u003e\n\u003cp\u003eThe 19RBW0J is suited for use in external and internal turning applications on CNC lathes and manual turning centers. The ENK chip breaker geometry and universal secondary workpiece material designation (M\/P) make it appropriate for a range of ferrous materials including carbon steels, alloy steels, and cast irons. It fits toolholders designed for CCMT-style inserts with a 0.112-inch hole diameter and M-tolerance, C-clearance specifications. Typical applications include finish turning, facing, and light profiling where consistent surface finish and close tolerances are required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAC830P grade CVD-coated solid carbide construction for extended tool life in steel and cast iron turning\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape (Shape Code C) provides strong cutting edge geometry for stable chip formation\u003c\/li\u003e\n  \u003cli\u003eENK chip breaker promotes reliable chip control during finish and semi-finish turning passes\u003c\/li\u003e\n  \u003cli\u003eNeutral hand orientation allows flexible toolholder pairing in standard CCMT setups\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle reduces cutting forces and heat generation at the insert edge\u003c\/li\u003e\n  \u003cli\u003eDual standard compliance with ANSI and ISO 13399 for broad toolholder compatibility verification\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement insert for screw-clamp CCMT-style toolholders accepting a 1\/4-inch inscribed circle, M-tolerance, C-clearance insert with a 0.112-inch mounting hole diameter.

Power down and lock out the spindle before indexing or replacing inserts. Use the manufacturer-specified torque driver for the screw-clamp holding method to avoid cracking the insert or stripping the toolholder pocket. Inspect the toolholder pocket and seating surface for debris or wear before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: CCMT21.51ENK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: CCMT060204N-SK\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond (Shape Code C)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: AC830P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: ENK\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: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 1\/4 inch (0.250 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.252 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 3\/32 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 1\/64 inch (0.0156 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.112 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eClearance Code\u003c\/strong\u003e: C\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: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Universal (M\/P)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: CC\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO 13399\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1 insert per package\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: 19RBW0J\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51752755429682,"sku":"19RBW0J","price":141.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e6ca804c19befc7f3d280bdf7dc2dfbb.jpg?v=1788930129","url":"https:\/\/voomisupply.com\/products\/sumitomo-19rbw0j-turning-insert-ccmt21-51enk-ac830p-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
