With a 3\/32 inch (0.0938 inch) mill diameter and four flutes, it delivers clean, accurate cuts in a compact form factor suited for fine-detail work. The micrograin carbide construction provides wear resistance and edge retention across a range of workpiece materials. The 15-degree helix angle and right-hand spiral flute geometry promote smooth chip evacuation during cutting. This tool is single-end and ships with a bright, uncoated finish. It is installed and used by machinists, tool-and-die professionals, and CNC operators working with precision milling equipment.\u003c\/p\u003e\u003cp\u003eThis end mill fits applications requiring small-diameter cutting in ferrous and non-ferrous metals, plastics, and composites. The 3\/8 inch length of cut and 1\/8 inch shank diameter make it appropriate for light finishing passes, slotting, and profiling in tight geometries. The regular-length profile suits standard milling setups where extended reach is not required. It is well-suited for CNC machining centers and manual mills where fine tolerances and small-feature work are common.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for durability and edge retention\u003c\/li\u003e\n\u003cli\u003eFour-flute design for improved surface finish and feed rate capability\u003c\/li\u003e\n\u003cli\u003e15-degree helix angle with right-hand spiral flutes for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry into workpieces\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish on 3\/32 inch diameter cutting edge\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration in OSG Series 409\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling option for milling operations requiring a 1\/8 inch shank, 3\/32 inch diameter square end mill in Series 409 configuration.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC operators. Ensure the machine spindle is fully powered down and locked out before changing tooling. Secure the 1\/8 inch shank in a compatible collet or end mill holder tightened to the machine manufacturer's specifications. Verify runout and tool projection before beginning a cut to maintain dimensional accuracy and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/32 inch (0.0938 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/8 inch (0.3750 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inch (1.5000 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inch)\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: 15 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\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\u003eFinish\u003c\/strong\u003e: Bright\/Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Single End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\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: 409\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 409-0938\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731967967538,"sku":"409-0938","price":26.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b9d309b553390479c44e45eb6ade8c90_11a47ffd-45ad-43ba-be09-7efadebb1eed.jpg?v=1788737388","url":"https:\/\/voomisupply.com\/products\/osg-409-0938-square-end-mill-3-32-in-4-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
