The shank features a 90-degree stepped configuration with a straight shank shape and a 0.312-inch shank diameter, making it compatible with standard Multimaster head connections. Constructed from steel, this shank delivers the rigidity required for consistent performance in milling applications. The T05 neck thread and 0.3-inch neck diameter allow precise coupling with Multimaster cutting heads. Coolant-through capability supports chip evacuation and thermal management during cutting.\u003c\/p\u003e\u003cp\u003eThis shank is suited for use in milling operations on machining centers where Multimaster-style modular tooling is employed. The 90-degree stepped shank style is commonly used in applications requiring a specific projection and clearance geometry. With an overall length of 2.5 inches and a projection of 0.6 inches, this shank fits standard tool assemblies in both production and job shop environments. It is installed and serviced by machinists and CNC tooling technicians.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e90-degree stepped shank geometry with straight shank shape for standard modular tool assembly\u003c\/li\u003e\n\u003cli\u003eT05 neck thread compatible with Multimaster cutting head series\u003c\/li\u003e\n\u003cli\u003eCoolant-through design supports chip evacuation and tool life in milling operations\u003c\/li\u003e\n\u003cli\u003eSteel construction provides rigidity for consistent milling performance\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.5 inches with 0.6-inch projection for precise reach control\u003c\/li\u003e\n\u003cli\u003eToolholder style MM S-A per manufacturers catalog number MM S-A-L2.50-C.312-T05\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement shank for Multimaster series modular milling tool assemblies using T05 neck thread cutting heads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC tooling technicians following shop tooling procedures. Power down and de-energize the spindle fully before removing or installing any tooling components. Use the appropriate torque wrench and Multimaster assembly tools as specified by the tooling system manufacturer. Inspect the neck thread and seating surfaces for damage or contamination before assembly to ensure accurate head-to-shank coupling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Multimaster\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: 90 Degree Stepped\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Shape\u003c\/strong\u003e: Straight\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.312 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Thread Size\u003c\/strong\u003e: T05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 0.51 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Length\u003c\/strong\u003e: 0.59 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MM S-A\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturers Catalog Number\u003c\/strong\u003e: MM S-A-L2.50-C.312-T05\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: ISCAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 3103409\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51739712422194,"sku":"3103409","price":150.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9a530f4f209391d5e402b8f0834e86bb_d2828b4a-3d29-4f84-b1b9-94a0867ceccd.jpg?v=1788818129","url":"https:\/\/voomisupply.com\/products\/iscar-3103409-multimaster-milling-shank-0-312-inch","provider":"Voomi Supply","version":"1.0","type":"link"}
