It features a 1\/2 inch cutting diameter, a 1-1\/4 inch length of cut, and a 45-degree helix angle that promotes efficient chip evacuation and smooth cutting action in softer, gummy materials. The three-flute geometry balances rigidity and chip clearance, making it well-suited for slotting, profiling, and peripheral milling operations. The bright uncoated finish is standard for aluminum applications, avoiding the built-up edge issues that can occur with coated tools on non-ferrous stock. Machinists and CNC operators in job shops and production environments are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use on CNC machining centers and manual mills where aluminum, copper, brass, and other non-ferrous workpiece materials are the primary stock. The 1\/2 inch straight shank fits standard ER collet chucks, end mill holders, and shrink-fit tooling systems commonly found in production and prototype shops. Its single-end configuration makes it a standard replacement tool for high-run non-ferrous machining programs. The Series A345 designation places it within SECO's solid carbide end mill line for non-ferrous and general-purpose applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide micrograin substrate for edge sharpness and wear resistance in non-ferrous materials\u003c\/li\u003e\n\u003cli\u003e45-degree helix angle promotes aggressive chip evacuation and reduces cutting forces in aluminum\u003c\/li\u003e\n\u003cli\u003eThree-flute design balances chip clearance with core strength for slotting and profiling\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish eliminates coating adhesion issues common with aluminum and copper alloys\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry in addition to peripheral and slot milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 1\/2 inch straight-shank solid carbide end mills used in non-ferrous milling applications.

Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Clean the collet bore and shank contact surfaces before seating the tool to maintain runout within specification. Confirm that TIR does not exceed 0.0005 inches after installation to preserve tool life and surface finish quality.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.0000 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\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\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Aluminum and Non-Ferrous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: -0.0000 \/ -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTIR Maximum\u003c\/strong\u003e: 0.0005 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: A345\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: 17003161\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51560779743538,"sku":"17003161","price":130.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e39ffcef59c3778b0674908b95ca55de_8eef683a-2707-4721-a339-6134d226839b.jpg?v=1786457210","url":"https:\/\/voomisupply.com\/products\/seco-17003161-square-end-mill-1-2-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
