Built from micrograin solid carbide and finished with an AlTiN coating, this head delivers heat and wear resistance in demanding cutting environments. It measures 0.125 inches in diameter with a 0.030-inch length of cut and mounts on a 0.25-inch cylindrical shank. Part of the MZN410R series, this single-end, stub-length head features a right-hand spiral flute geometry and a 10-degree helix angle. It is installed by machinists and tool-and-die professionals working on CNC milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill head is suited for precision milling operations where extended reach into cavities, pockets, or complex contours is required. The 0.375-inch reach length and 0.112-inch neck diameter allow access to features that standard-length tooling cannot reach. The 2.5-inch overall length supports setups in multi-axis CNC machining centers handling detail work in mold, die, and aerospace component production. It is not centercutting, making it appropriate for side-milling and profiling passes rather than direct plunge entry.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention at small diameters\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides elevated heat resistance and extended tool life in ferrous and hardened materials\u003c\/li\u003e\n\u003cli\u003eExtended-reach design with 0.375-inch reach length and reduced 0.112-inch neck diameter for deep-cavity access\u003c\/li\u003e\n\u003cli\u003e4-flute right-hand spiral geometry optimized for finish milling passes\u003c\/li\u003e\n\u003cli\u003e10-degree helix angle supports smooth chip evacuation in shallow-depth cuts\u003c\/li\u003e\n\u003cli\u003eCylindrical shank mates with standard MZN410R series toolholders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with the SECO MZN410R series modular tooling system.

Torque the toolholder to the system specifications provided by the holder manufacturer. Inspect the shank and seating surfaces for contamination or damage before assembly. Do not use this head for plunge cutting, as it is a non-centercutting design.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: MZN410R\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.030 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.112 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 10 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\/Coating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Stub\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003ePackage Weight\u003c\/strong\u003e: 0.09 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 02941971\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559031275826,"sku":"02941971","price":139.07,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c3a6db318343ec92ba7a27f070d76c9.jpg?v=1786426266","url":"https:\/\/voomisupply.com\/products\/seco-02941971-corner-radius-end-mill-head-1-8-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
