It features a 1\/4 inch cutting diameter, a 3\/4 inch length of cut, and a 4-flute configuration with a 30-degree variable helix angle. The variable helix geometry reduces chatter and improves surface finish during high-feed milling operations. Made from micrograin carbide and finished with an HTA coating, this single-end tool is built for consistent performance in demanding shop environments. It is installed and operated by machinists and CNC technicians across job shop and production settings.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling steel and cast iron in light to moderate roughing and finishing passes, as well as aluminum and non-ferrous alloys where a sharp, center-cutting geometry is required. The 1\/4 inch shank diameter makes it compatible with standard collet chucks and end mill holders on vertical machining centers and CNC milling machines. The standard length profile and right-hand cut and flute direction suit general-purpose milling applications where reach is not a limiting factor.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1\/4 inch cutting diameter with 3\/4 inch length of cut for controlled material removal\u003c\/li\u003e\n  \u003cli\u003e4-flute, 30-degree variable helix design reduces chatter and improves finish quality\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for edge retention in ferrous and non-ferrous materials\u003c\/li\u003e\n  \u003cli\u003eHTA coating enhances heat resistance and tool life in steel and cast iron applications\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capable for plunge entry and ramping operations\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flutes with no chipbreaker for smooth chip evacuation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for 1\/4 inch collet chucks, shrink-fit holders, and end mill holders on CNC vertical machining centers.

Ensure the spindle is fully stopped and the machine is in an e-stop or lockout state before changing tooling. Verify collet or holder runout before tightening to specification for the holder type in use. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and depth of cut being applied.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches (2.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees, variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: HTA\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 Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single End\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCenter Cutting\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\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: STS430.2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Cast Iron, Aluminum and Non-Ferrous\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.94 inches L x 0.48 inches W x 0.48 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: SECO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 10008530\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SECO TOOLS","offers":[{"title":"Default Title","offer_id":51559683424562,"sku":"10008530","price":93.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0cf9f4fdaf3e7fde9b719c73710e39bf.jpg?v=1786438065","url":"https:\/\/voomisupply.com\/products\/seco-10008530-square-end-mill-1-4in-4-flute-carbide-hta","provider":"Voomi Supply","version":"1.0","type":"link"}
