Constructed from solid carbide, this shank features a 90-degree stepped design with a 5\/8-inch (0.625-inch) shank diameter and a T10 neck thread. It delivers a projection of 3.5 inches and an overall length of 5.5 inches, making it suitable for deep-reach milling operations where rigidity and precision matter. The MM S-A toolholder style accommodates a wide range of Multimaster cutting heads, enabling quick head changes without removing the shank from the machine spindle. Coolant-through capability supports chip evacuation and thermal control during demanding cuts.\u003c\/p\u003e\u003cp\u003eThis shank is intended for use on CNC machining centers in metalworking environments, both in production shops and tool rooms. It is installed by machinists and tooling specialists working with modular end-milling, profiling, and slotting operations. The 90-degree stepped shank geometry is appropriate for toolholders requiring a secure, positive-stop seating arrangement. With a neck diameter of 0.6 inches and a head length of 3.43 inches, it supports close-tolerance work in tighter clearance zones.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for high rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eT10 neck thread for Multimaster modular head interface\u003c\/li\u003e\n\u003cli\u003eCoolant-through design aids chip removal and cutting zone cooling\u003c\/li\u003e\n\u003cli\u003e90-degree stepped shank provides positive seating in compatible toolholders\u003c\/li\u003e\n\u003cli\u003e5\/8-inch shank diameter suits standard ER and side-lock holders in MM S-A style\u003c\/li\u003e\n\u003cli\u003e3.5-inch effective length supports extended-reach milling applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use within the ISCAR Multimaster modular tooling system, MM S-A toolholder style, accepting T10-threaded Multimaster cutting heads.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the machine spindle fully stopped and the control in an E-stop or lockout-tagout state per applicable shop safety procedures. Use the correct Multimaster torque wrench or assembly key for head engagement — do not use improvised tools on the threaded interface. Verify shank seating and runout with a dial indicator before initiating cuts. Coolant-through passages should be inspected and cleared before assembly to ensure unrestricted flow.\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\u003eToolholder Style\u003c\/strong\u003e: MM S-A\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: 0.625 inches (5\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Thread Size\u003c\/strong\u003e: T10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProjection\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length\u003c\/strong\u003e: 3.43 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Material\u003c\/strong\u003e: Solid Carbide\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\u003eManufacturer Catalog Number\u003c\/strong\u003e: MM S-A-L5.50-C.625-T10-C\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: 3103517\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ISCAR","offers":[{"title":"Default Title","offer_id":51734714876210,"sku":"3103517","price":871.27,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05792479d378e0dd23add84aae3321dd.jpg?v=1788765752","url":"https:\/\/voomisupply.com\/products\/iscar-3103517-multimaster-milling-shank-5-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
