Part of the Multimaster and SolidThread interchangeable tip system, it carries the full designation MM TRD22-W55-14P-4T08 and mounts to compatible MM TRD-W style arbors. The tip is ground from sub-micrograin carbide and coated with TiAlN via a PVD process, delivering hardness and thermal resistance needed for demanding thread profiles. With a 0.854 inch cutting diameter, a 4-flute configuration, and a 90-degree included angle, it is suited for right-hand thread forms across a broad range of workpiece materials. Licensed machinists and CNC tooling technicians are the primary installers.\u003c\/p\u003e\n\u003cp\u003eThis tip is engineered for thread milling across multiple material categories including steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials. It conforms to ANSI standards and is appropriate for both production and job-shop environments where a single tooling platform needs to handle varied workpiece materials without changing arbors. The 0.0079 inch corner radius keeps edge geometry consistent through thread profiles, and the absence of a chipbreaker keeps the geometry clean for threading operations where chip geometry is controlled by feed and speed parameters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSub-micrograin carbide substrate with PVD TiAlN coating for extended tool life in hard and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e4-flute, right-hand cut geometry with 0.854 inch cutting diameter and 90-degree included angle\u003c\/li\u003e\n  \u003cli\u003eCorner radius of 0.0079 inches for consistent thread form accuracy\u003c\/li\u003e\n  \u003cli\u003eCompatible with Multimaster and SolidThread interchangeable arbor systems\u003c\/li\u003e\n  \u003cli\u003eRated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials\u003c\/li\u003e\n  \u003cli\u003eANSI-standard geometry; no coolant-through requirement simplifies setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with ISCAR Multimaster and SolidThread series toolholders accepting the MM TRD-W interface.

Use the recommended ISCAR torque wrench or key for the Multimaster interface to ensure proper seating without over-torquing the tip connection. Inspect the mating arbor nose for wear or contamination before installing a new tip. Follow shop-specific speeds and feeds for the target workpiece material category as no generic values apply across all supported materials.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMilling Tip Style\u003c\/strong\u003e: MM TRD-W\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFull Tip Designation\u003c\/strong\u003e: MM TRD22-W55-14P-4T08\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Size\u003c\/strong\u003e: D22-W55-14P\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 0.854 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Width\u003c\/strong\u003e: 0.854 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInsert Hand\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLead Angle\u003c\/strong\u003e: 90 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChamfer Angle\u003c\/strong\u003e: 0 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0079 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Sub Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Grade\u003c\/strong\u003e: IC908\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiAlN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating Process\u003c\/strong\u003e: PVD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: None\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: ANSI\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multimaster \/ SolidThread\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.097 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Order Quantity\u003c\/strong\u003e: 2\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: ISCAR\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 6403866\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51750018220338,"sku":"6403866","price":201.08,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e395c58775a8e122467cd37eaaf199f5.jpg?v=1788913151","url":"https:\/\/voomisupply.com\/products\/iscar-6403866-thread-mill-tip-0-854-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
