It features a 0.5-inch cutting diameter, a 3-flute helical geometry with a 35-degree helix angle, and an extended reduced-neck design that provides 5 inches of reach length for deep-cavity and long-reach operations. The uncoated bright finish is suited to aluminum, where coatings can cause material adhesion. Overall length is 7 inches with a 0.625-inch length of cut, making this tool appropriate for slotting, profiling, and pocketing in aluminum workpieces on CNC machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in aluminum and other non-ferrous machining environments where chip evacuation and surface finish are critical. The reduced neck geometry allows access to deep features and thin-wall pockets without sacrificing rigidity at the cutting edge. Right-hand cut and right-hand flute direction are standard for conventional CNC milling setups. The straight-cylindrical shank fits standard ER collet chucks and end mill holders with a 0.5-inch bore. It is sold individually and is appropriate for job shop, production, and prototype work in aluminum.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e3-flute helical design optimized for aluminum chip evacuation and surface finish\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle reduces cutting forces and improves finish in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003eReduced neck with 5-inch reach length enables deep-pocket and long-reach operations\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable — supports plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish prevents aluminum adhesion on cutting edges\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction provides rigidity and wear resistance at high feeds and speeds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines equipped with 0.5-inch ER collet chucks, shrink-fit holders, or end mill holders with a straight-cylindrical bore.

Ensure the machine spindle is fully stopped and the tool changer or drawbar is disengaged before inserting or removing the end mill. Seat the shank fully into the holder to the recommended minimum engagement depth per holder manufacturer guidelines before torquing the collet nut or set screw. Verify runout with a dial indicator after tool installation and before initiating a cut program to prevent premature tool wear or workpiece damage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\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 (5\/8 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 inches (1\/2 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\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\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\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eWeight\u003c\/strong\u003e: 0.631 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: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 83451\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51731678363954,"sku":"83451","price":208.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4c06a3e7b684e82cda1911b64f20cd2a.jpg?v=1788733808","url":"https:\/\/voomisupply.com\/products\/helical-solutions-83451-square-end-mill-0-5in-3-flute-aluminum","provider":"Voomi Supply","version":"1.0","type":"link"}
