This single-end tool features 4 helical flutes with a variable helix angle ranging from 38 to 41 degrees, which helps reduce chatter and improve surface finish across a range of cutting conditions. The variable index geometry further distributes cutting forces unevenly to suppress vibration. With a straight shank diameter of 5\/16 inches and a right-hand cutting direction, this head suits modular tooling systems used by machinists and tool-and-die professionals in production and job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill head is suited for profiling, contouring, and finishing passes where a corner radius edge form is required to reduce stress concentrations in the workpiece. The solid carbide construction provides the rigidity and wear resistance needed for high-speed machining in hardened steels, stainless alloys, and aluminum. It is intended for use in CNC machining centers and manual mills where a modular end mill system accepts straight-shank replacement heads. Single-end configuration makes it a direct swap-out when the cutting end is worn without discarding the full tool assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for high rigidity and extended tool life\u003c\/li\u003e\n  \u003cli\u003e4 helical flutes with variable helix angle (38 to 41 degrees) to reduce chatter\u003c\/li\u003e\n  \u003cli\u003eVariable index spacing to distribute cutting forces and suppress vibration\u003c\/li\u003e\n  \u003cli\u003eCorner radius end type reduces stress risers and improves part finish\u003c\/li\u003e\n  \u003cli\u003eRight-hand flute direction and cutting direction for standard CNC spindle compatibility\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch straight shank diameter for modular tooling system interface\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement corner radius end mill head for modular tooling systems that accept a straight shank at 5\/16 inches.

Ensure the spindle and toolholder are fully de-energized and at rest before changing cutting heads. Inspect the shank seating surface and locking mechanism for wear or debris before assembly. Follow all applicable shop safety protocols and machine guarding requirements during setup.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: 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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Helix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Helix Angle\u003c\/strong\u003e: 41 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 277L3122B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51746547892530,"sku":"277L3122B","price":177.86,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/52cdf581d77395a44ecdc13580d5628a_73d4e485-0eba-46be-84aa-264ef81a910f.jpg?v=1788871199","url":"https:\/\/voomisupply.com\/products\/m-a-ford-277l3122b-corner-radius-end-mill-head-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
