Built on SECO's MZ645 series, this single-end mill features a 0.125-inch cutting diameter, six spiral flutes, and a 45-degree helix angle that promotes aggressive chip evacuation and smooth cutting action. The AlTiN coating provides thermal resistance and hardness, making this tool well suited for dry or semi-dry machining at elevated cutting speeds. Micrograin carbide substrate adds toughness and edge retention. It is center-cutting, right-hand cut, with a straight cylindrical shank measuring 0.25 inches in diameter and a 3-inch overall length.\u003c\/p\u003e\u003cp\u003eThis end mill is engineered for machining hardened materials and steel in precision milling applications. The 0.375-inch length of cut and 0.38-inch reach length make it appropriate for shallow-to-moderate depth passes in die and mold work, toolroom operations, and production milling where tight tolerances and surface finish matter. A 0.005-inch maximum TIR specification reflects the close tolerances held on this tool. It is suited for CNC machining centers and manual mills with appropriate spindle speeds and feed rates for the workpiece material.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eAlTiN coating for thermal resistance in hardened steel and difficult alloys\u003c\/li\u003e\n\u003cli\u003eSix flutes with 45-degree spiral helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for edge retention and rigidity\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry\u003c\/li\u003e\n\u003cli\u003eStraight cylindrical shank with tight diameter tolerance of -0.0001\/-0.0003 inches\u003c\/li\u003e\n\u003cli\u003eMaximum TIR of 0.0005 inches for precise, repeatable cuts\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement or production-use square end mill in the SECO MZ645 series, intended for use with standard 0.25-inch collets or end mill holders on CNC machining centers and manual mills cutting hardened materials and steel.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a machinist or CNC operator using a properly sized collet or end mill holder rated for the 0.25-inch shank diameter. Ensure the holder and spindle are clean and free of debris before seating the tool. Confirm runout at the cutting edge before commencing a cut, particularly given the close TIR specification. Always reference the machine tool manufacturer's guidelines and appropriate cutting data for AlTiN-coated carbide tooling when establishing spindle speed and feed rate.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Hardened Materials, Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001\/-0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0600\/-0.0600 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum TIR\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MZ645\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: SECO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17004769\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559755022642,"sku":"17004769","price":196.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/aad808e64d0a260b2fe9451df670f1e7_0194c30b-3a9c-4d49-a585-6920763bceae.jpg?v=1786440100","url":"https:\/\/voomisupply.com\/products\/seco-17004769-square-end-mill-0-125in-6-flute-altin-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
