The insert features a multilayer CVD coating of TiCN, Al2O3, and TiN applied over a carbide substrate, building wear resistance for both abrasive and thermally intensive cuts. The 80-degree diamond (rhombic) shape provides a strong cutting edge with positive rake and positive side clearance, while the PM5 chip breaker geometry handles roughing and medium machining operations. Insert length is 0.508 inches (12.9 mm), inscribed circle is 0.5 inches, and corner radius is 0.0315 inches (1\/32 inch). The part is screw-held and suited for turning, facing, and boring operations.\u003c\/p\u003e\n\u003cp\u003eThis insert is designed for primary use in cast iron (ISO material code K, grade K20) and secondary use in steel (ISO material code P, grade P10). Typical applications include roughing and medium-finish passes on CNC turning centers in production machining environments, automotive component shops, and general metalworking facilities. The neutral hand orientation makes it compatible with standard right-hand and left-hand toolholders configured for CCMT-style inserts. The two available cutting edges support tool rotation to extend usable life between changeovers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMultilayer CVD coating: TiCN plus Al2O3 plus TiN for thermal and abrasion resistance\u003c\/li\u003e\n  \u003cli\u003e80-degree diamond insert shape with positive rake and 7-degree relief angle\u003c\/li\u003e\n  \u003cli\u003ePM5 chip breaker geometry rated for roughing and medium machining\u003c\/li\u003e\n  \u003cli\u003eTwo cutting edges per insert; screw-held mounting for secure clamping\u003c\/li\u003e\n  \u003cli\u003eHoned cutting edge style reduces microchipping on entry\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO dimensional standards (CCMT432 and CCMT120408)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit insert for CCMT432 toolholders conforming to ANSI and ISO standards.

Power down and lock out the machine spindle before seating or rotating the insert. Use the correct torx or hex key specified by the toolholder manufacturer to seat the clamping screw  -  do not overtighten, as carbide inserts are brittle and will crack under excessive clamping force. Confirm insert seating and edge orientation before resuming spindle operation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Insert Code\u003c\/strong\u003e: CCMT432\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Insert Code\u003c\/strong\u003e: CCMT120408\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN, Al2O3, TiN (Multilayer CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WAK20\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: K20, P10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: C - Diamond (Rhombic) 80-Degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: PM5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker Operation\u003c\/strong\u003e: Roughing, Medium Machining\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: 0.508 inches (12.9 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Thickness\u003c\/strong\u003e: 0.1875 inches (3\/16 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (1\/32 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.217 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.197 inches (5.0 mm)\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: 12 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSide Clearance\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake\u003c\/strong\u003e: Positive\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Cast Iron (ISO Code K)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Steel (ISO Code P)\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: 0.022 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: WALTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 5022077\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":52102412239154,"sku":"5022077","price":337.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a76bc2257a36f4ddbd58bf1d517bfa0d_d12ea531-d99f-444a-a4a3-78f5fdfa49b1.jpg?v=1790070460","url":"https:\/\/voomisupply.com\/products\/walter-5022077-turning-insert-ccmt432-pm5wak20-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
