It features an AXMT insert style with a parallelogram shape and an 85-degree included angle. The insert carries SUMITOMO grade ACM200 with a CVD coating process applied over a solid carbide substrate. It measures 0.47 inches in cutting edge effective length, 0.26 inches in inscribed circle diameter, and 0.14 inches in thickness. A corner radius of 0.0315 inches (0.80 mm) and an 11-degree relief angle support controlled chip formation and edge stability. This insert is installed by machinists and tooling technicians in milling operations requiring consistent performance on difficult-to-cut materials.\u003c\/p\u003e\u003cp\u003eThis insert is suited for milling stainless steel and superalloys in both production and job-shop environments. It is compatible with the SUMITOMO WEX2000 cutter series and is configured for right-hand cutting. The chip breaker style is E. Maximum depth of cut reaches 0.3940 inches (10.00 mm), making it appropriate for moderate to aggressive radial and axial engagement passes on vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eACM200 grade solid carbide substrate with CVD coating for extended tool life on hard and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eParallelogram insert shape (AXMT style) with 85-degree included angle for stable pocket seating\u003c\/li\u003e\n\u003cli\u003eCorner radius of 0.0315 inches (0.80 mm) for controlled surface finish on stainless steel and superalloys\u003c\/li\u003e\n\u003cli\u003eMaximum depth of cut of 0.3940 inches (10.00 mm) supports versatile engagement strategies\u003c\/li\u003e\n\u003cli\u003eRight-hand cutting configuration with E chip breaker geometry\u003c\/li\u003e\n\u003cli\u003eCVD coating process provides thermal resistance and wear protection under high-speed cutting conditions\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the SUMITOMO WEX2000 cutter series.

Seat the insert fully into the pocket and verify torque on the clamping screw follows the cutter body manufacturer's specification. Inspect the insert pocket for chips or debris before seating a new insert to prevent improper seating and premature edge failure. Dispose of worn carbide inserts in accordance with local regulations for carbide and coated tooling waste.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: AXMT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Parallelogram\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: ACM200\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Coated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: CVD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 85 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0315 inches (0.80 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.2600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1400 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Edge Effective Length\u003c\/strong\u003e: 0.4720 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.3940 inches (10.00 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInsert Size Code\u003c\/strong\u003e: 1235\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: WEX2000\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 144V421\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SUMITOMO","offers":[{"title":"Default Title","offer_id":51739623653682,"sku":"144V421","price":158.04,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/38fb3d15ce75cbfed3d20f7215170317.jpg?v=1788817053","url":"https:\/\/voomisupply.com\/products\/sumitomo-144v421-milling-insert-acm200-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
