It features a 1\/2-inch cutting diameter, a 5\/8-inch length of cut, and a 40-degree high helix angle that promotes fast chip evacuation and reduces heat buildup in the cut zone. The variable pitch flute index minimizes chatter and vibration during aggressive passes. A reduced neck profile with a 0.475-inch neck diameter and 3.37-inch reach length makes this tool well-suited for deep-pocket and extended-reach operations. Licensed machinists and CNC programmers in production and job-shop environments rely on this geometry for both roughing and finishing in a single setup.\u003c\/p\u003e\n\u003cp\u003eThis end mill is intended for non-ferrous metal applications, with aluminum alloys as the primary workpiece material. The uncoated bright finish is appropriate for aluminum where coatings can cause material adhesion. The single-end, straight-cylindrical shank with h6 tolerance fits standard 1\/2-inch tool holders. The 5-inch overall length combined with the reduced neck allows access into deep features without sacrificing rigidity at the shank. This tool is suited for vertical machining centers and high-speed CNC routers running aluminum structural components, mold cavities, and aerospace-profile parts.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e3-flute variable-index geometry reduces harmonics and chatter during high-feed passes\u003c\/li\u003e\n  \u003cli\u003e40-degree high helix angle promotes aggressive chip evacuation in aluminum and non-ferrous cuts\u003c\/li\u003e\n  \u003cli\u003eReduced neck diameter of 0.475 inches enables deep-pocket and extended-reach applications\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction provides rigidity and wear resistance across roughing and finishing operations\u003c\/li\u003e\n  \u003cli\u003eUncoated bright finish prevents aluminum adhesion and galling on the flute surfaces\u003c\/li\u003e\n  \u003cli\u003eh6 shank and mill diameter tolerances ensure accurate, repeatable tool-holder fitment\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in 1\/2-inch tool holders on CNC vertical machining centers and high-speed routers.

Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before loading the tool. Use a calibrated tool-holder torque procedure per the tool-holder manufacturer specification and confirm runout against the 0.0003-inch maximum TIR rating before cutting. Coolant-through is not supported on this tool; apply flood or mist coolant externally as appropriate for the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNose Radius\u003c\/strong\u003e: 0.2500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Diameter\u003c\/strong\u003e: 0.4750 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNeck Length\u003c\/strong\u003e: 2.7450 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3.3700 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0003 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.437 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: HELICAL SOLUTIONS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 47255\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51728572940594,"sku":"47255","price":191.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82b99d2acc0025de4ad58fe3222a3757.jpg?v=1788693496","url":"https:\/\/voomisupply.com\/products\/helical-solutions-47255-ball-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
