Manufactured from cermet and finished with a PVD TiCNO coating, this insert delivers consistent performance across steel, stainless steel, and cast iron workpieces. The diamond 80-degree insert shape and positive rake angle reduce cutting forces while the honed cutting edge improves surface finish and edge stability. With a 0.016 inch corner radius and a 0.25 inch inscribed circle, this insert suits light-to-medium material removal in finish turning and semi-finish turning operations. It is installed via screw-holding method and carries the PF chip breaker geometry for controlled chip flow.\u003c\/p\u003e\u003cp\u003eThis insert is suited for turning, facing, and boring operations on steel (P10, P20), stainless steel (M20), and cast iron (K10) workpieces. It is commonly applied in production environments where tight tolerances and repeatable surface quality are required. The neutral hand orientation makes it adaptable across a range of toolholder setups without requiring dedicated left- or right-hand configurations. Machinists and CNC programmers working in aerospace, automotive, and general machining will find this insert appropriate for finishing passes and controlled depth-of-cut applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eCermet substrate with PVD TiCNO coating for wear resistance on steel and stainless steel\u003c\/li\u003e\n\u003cli\u003eDiamond 80-degree insert shape with positive 10-degree rake angle reduces cutting forces\u003c\/li\u003e\n\u003cli\u003ePF chip breaker geometry promotes controlled chip evacuation during finish turning\u003c\/li\u003e\n\u003cli\u003eHoned cutting edge style improves edge integrity and surface finish consistency\u003c\/li\u003e\n\u003cli\u003eNeutral hand design offers toolholder flexibility across standard CCMT holders\u003c\/li\u003e\n\u003cli\u003eScrew-clamp holding method ensures secure seating under interrupted and continuous cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement insert for standard CCMT 21.51 screw-on turning toolholders. Compatible workpiece materials include steel, stainless steel, and cast iron at material grades P10, P20, M20, and K10.

Power down and lock out the spindle before seating or rotating the insert. Verify insert pocket cleanliness and seat contact before torquing the clamp screw to the toolholder manufacturer specification. Do not exceed the maximum depth of cut of 0.059 inches to avoid overloading the cutting edge.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: CCMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustry Standard Number\u003c\/strong\u003e: CCMT 21.51 PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: GT9530\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Cermet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCNO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Diamond 80\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape Code\u003c\/strong\u003e: C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 80 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: Positive\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 7 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0157 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Length\u003c\/strong\u003e: 0.256 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.0938 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.11 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.059 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: P10, P20, M20, K10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-Use Application\u003c\/strong\u003e: Turning, Facing, Boring\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.037 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: TUNGALOY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6998285\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TUNGALOY","offers":[{"title":"Default Title","offer_id":51972609605938,"sku":"6998285","price":140.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f6a8dd296bab35e8a809173cd9fd8c21.jpg?v=1789969965","url":"https:\/\/voomisupply.com\/products\/tungaloy-6998285-turning-insert-ccmt21-51pf-gt9530","provider":"Voomi Supply","version":"1.0","type":"link"}
