With a 1\/4-inch cutting diameter, a 3\/8-inch length of cut, and a 45-degree helix angle, this tool is built to evacuate chips efficiently and reduce built-up edge when cutting non-ferrous materials. The reduced neck design provides extended reach of 2.125 inches, allowing access to deeper pockets and features without sacrificing rigidity. It is single-end, right-hand cutting, and arrives with a bright uncoated finish ready for immediate use. Machinists and CNC operators in production and job-shop environments are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for cutting aluminum and other non-ferrous materials where high helix angles improve chip flow and surface finish. The reduced neck geometry makes it suitable for deep-pocket milling, profiling, and slotting operations where clearance is limited. The straight cylindrical shank fits standard ER collets and end mill holders commonly found on vertical machining centers and CNC routers. It is sold as a single unit and is appropriate for both prototype work and production runs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4-inch cutting diameter with 3\/8-inch length of cut for precise, controlled engagement\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes efficient chip evacuation in aluminum and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eReduced neck design provides 2.125-inch reach length for deep-pocket and hard-to-reach features\u003c\/li\u003e\n  \u003cli\u003eSolid carbide construction delivers rigidity and wear resistance compared to HSS tooling\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n  \u003cli\u003eBright uncoated finish suitable for aluminum where certain coatings can cause material adhesion\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard 1\/4-inch straight cylindrical shank tool holders, ER collet chucks, and end mill holders on vertical machining centers and CNC routers.

Ensure the spindle is fully stopped and the machine is in a safe, locked state before changing tooling. Confirm proper collet size and torque the tool holder to the machine manufacturer's specification using the appropriate spanner wrench. Verify runout with an indicator after installation to confirm seating before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.375 inches (3\/8 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.250 inches (1\/4 inch)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 2.125 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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: Helical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003eWeight\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\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: 19135\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51729333092658,"sku":"19135","price":99.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/903777ce24302aa8d74cb77c3534d7df.jpg?v=1788703062","url":"https:\/\/voomisupply.com\/products\/helical-solutions-19135-square-end-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
