With a 0.3937 inch cutting diameter and a 0.9843 inch length of cut, this tool delivers clean, flat-bottomed slots, shoulders, and profiles in ferrous and non-ferrous workpieces. The micrograin carbide construction provides the rigidity and edge retention needed for demanding cuts at tight tolerances. A 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. This tool is installed and used by machinists and CNC operators in job shop, manufacturing, and maintenance environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for general-purpose milling applications including slotting, profiling, and peripheral milling on machining centers and manual mills. The 0.3937 inch shank diameter matches the cutting diameter for direct collet or end mill holder mounting. Its centercutting geometry allows plunge entry, expanding its range of use in pocket milling operations. The uncoated finish makes it a straightforward choice for applications where regrinding or cost-per-edge economics are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e0.3937 inch cutting diameter with 0.9843 inch length of cut\u003c\/li\u003e\n  \u003cli\u003e2-flute design for efficient chip clearance in slotting and plunge cuts\u003c\/li\u003e\n  \u003cli\u003e30-degree helix angle for smooth cutting action and reduced vibration\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry enables direct plunge entry\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute configuration\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for regrinding or applications where coating is not required\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in standard collet chucks, end mill holders, or shrink-fit toolholders accepting a 10 mm (0.3937 inch) shank diameter.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool. Seat the shank fully into the toolholder to the recommended gauge line and verify runout before initiating a cut. Follow machine tool manufacturer specifications for speed and feed parameters appropriate to the workpiece material.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.3937 inches (10.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.9843 inches (25.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 70.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 10.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 402\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.15 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: OSG\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 402-3937\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51731859079474,"sku":"402-3937","price":55.26,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ec2810032522a197d606edf2de6f45a4.jpg?v=1788735675","url":"https:\/\/voomisupply.com\/products\/osg-402-3937-square-end-mill-0-3937-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
