The shank features a 5\/8 inch (0.625 inch) straight keyway configuration with a Weldon flat for secure toolholder engagement. With an overall length of 2.56 inches and a neck diameter of 0.508 inches, this shank provides a 17 mm (0.669 inch) head projection suited for applications requiring controlled reach and rigidity. It is installed by machinists and tooling technicians in CNC milling operations where quick tip changes and consistent runout are critical.\u003c\/p\u003e\u003cp\u003eThis shank is used in CNC milling setups requiring the Minimaster MM12 tip system. The 17 mm projection and 0.625 inch shank diameter make it appropriate for light to moderate material removal operations in both production and job-shop environments. The Weldon flat on the shank ensures positive drive retention in standard side-lock toolholders, reducing tip pullout risk during cutting.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMinimaster MM12 tip interface accepts interchangeable milling heads for quick changeovers\u003c\/li\u003e\n\u003cli\u003e5\/8 inch (0.625 inch) straight shank with Weldon flat for positive side-lock retention\u003c\/li\u003e\n\u003cli\u003e17 mm projection providing controlled reach with minimal overhang\u003c\/li\u003e\n\u003cli\u003eNeck diameter of 0.508 inches for clearance in close-tolerance applications\u003c\/li\u003e\n\u003cli\u003eOverall length of 2.56 inches in a compact, rigid profile\u003c\/li\u003e\n\u003cli\u003eEffective cutting length of 0.602 inches with maximum diameter of 0.625 inches\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the Seco Minimaster MM12 series replaceable milling tip heads.

Secure the shank in a compatible side-lock toolholder by tightening the set screw against the Weldon flat before mounting in the spindle. Ensure the machine spindle is fully stopped and the control is in a safe state before installing or removing the shank or tip. Follow the machine tool manufacturer and toolholder manufacturer torque guidelines for set screw engagement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Minimaster\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eToolholder Style\u003c\/strong\u003e: MM12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMilling Tip Style\u003c\/strong\u003e: MM12\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTool Application\u003c\/strong\u003e: Milling\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Keyway\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: 5\/8 inch (0.625 inches \/ 15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.508 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.56 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Length (Projection)\u003c\/strong\u003e: 17 mm (0.669 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEffective Length\u003c\/strong\u003e: 0.602 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Diameter\u003c\/strong\u003e: 0.625 inches (15.88 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeldon Flat\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 75005070\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560187330866,"sku":"75005070","price":197.47,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ac0f1b6b3ed9c46dfa69f659922b9d60.jpg?v=1786448666","url":"https:\/\/voomisupply.com\/products\/seco-75005070-minimaster-milling-shank-5-8-in-keyway-mm12","provider":"Voomi Supply","version":"1.0","type":"link"}
