It carries manufacturer grade WSM45X with a CVD-applied multilayer coating of TiCN, Al2O3, and TiCN for wear resistance and thermal stability. The insert measures 0.4720 inches in inscribed circle diameter (12.00 mm) with a thickness of 0.1875 inches (4.76 mm) and delivers a maximum depth of cut of 0.2360 inches (12.70 mm). Four cutting edges, a positive rake angle of 10 degrees, an 11-degree relief angle, and a honed cutting edge style make this insert suited for demanding milling in stainless steel, superalloys, and titanium. A licensed machinist or CNC tooling technician is the typical installer.\u003c\/p\u003e\n\u003cp\u003eThis insert is engineered for milling stainless steel, superalloys, and titanium in both production and job-shop environments. The D57 chip breaker geometry supports controlled chip evacuation in tough, work-hardening materials. The neutral hand orientation allows flexible application across a variety of milling setups. The ROMX1204M0-D57 ANSI and ISO designation aligns this insert with the F2334R cutter series for direct drop-in use. It is appropriate for both roughing and semi-finishing passes where consistent edge life in difficult materials is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide substrate with CVD multilayer TiCN, Al2O3, TiCN coating for extended tool life in abrasive materials\u003c\/li\u003e\n  \u003cli\u003eRound insert shape (ROMX series) with 360-degree included angle and 4 usable cutting edges\u003c\/li\u003e\n  \u003cli\u003eD57 chip breaker geometry optimized for stainless steel, superalloys, and titanium\u003c\/li\u003e\n  \u003cli\u003ePositive rake angle (10 degrees) and honed cutting edge reduce cutting forces and chipping risk\u003c\/li\u003e\n  \u003cli\u003eScrew-held, single-sided, neutral-hand insert for consistent seating and repeatable runout\u003c\/li\u003e\n  \u003cli\u003eMeets ANSI and ISO standards; ANSI and ISO code ROMX1204M0-D57 WSM45X\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eConfirmed compatible with the F2334R cutter series.

Power down and lock out the machine spindle completely before changing inserts. Use the correct torx or hex key to the cutter body manufacturers specified seating torque for the insert screw  -  do not overtighten, as carbide inserts are brittle and can crack under excessive clamp load. Inspect the pocket seat and locating surfaces for chips or debris before seating the new insert.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Style\u003c\/strong\u003e: ROMX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: WSM45X\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, TiCN (CVD)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Cutting Edges\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInscribed Circle\u003c\/strong\u003e: 0.4720 inches (12.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 0.1875 inches (4.76 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Depth of Cut\u003c\/strong\u003e: 0.2360 inches (12.70 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.2362 inches (6.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRelief Angle\u003c\/strong\u003e: 11 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRake Angle\u003c\/strong\u003e: 10 degrees (Positive)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Edge Style\u003c\/strong\u003e: Honed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChip Breaker\u003c\/strong\u003e: D57\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Neutral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHole Diameter\u003c\/strong\u003e: 0.1728 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Holding Method\u003c\/strong\u003e: Screw\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSided\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Series Compatibility\u003c\/strong\u003e: F2334R\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI, ISO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eANSI Code\u003c\/strong\u003e: ROMX1204M0-D57 WSM45X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eISO Code\u003c\/strong\u003e: ROMX1204M0-D57 WSM45X\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.011 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: 6841390\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"WALTER","offers":[{"title":"Default Title","offer_id":51995172929842,"sku":"6841390","price":47.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1f218e9155f591ed4709489514afc2c6.jpg?v=1789992519","url":"https:\/\/voomisupply.com\/products\/walter-6841390-round-milling-insert-wsm45x-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
