Built on OSG Series 3670, this single-end tool features a 1\/4 inch diameter, a 0.03 inch corner radius, and four helical right-hand flutes with a 30-degree helix angle. The WXL PVD coating extends tool life by improving wear resistance and heat dissipation at the cutting edge. Centercutting capability allows the tool to plunge directly into the workpiece. It is used by machinists and CNC operators running production runs on steel, stainless steel, cast iron, non-ferrous metals, superalloys, titanium, and hard materials.\u003c\/p\u003e\u003cp\u003eThis end mill suits both roughing and finishing passes in a single setup, reducing tool changes on tight-tolerance parts. The 3\/4 inch length of cut and 2.5 inch overall length make it a compact, rigid option for shallow-to-medium depth pockets and profiles. The straight cylindrical shank fits standard collet-style toolholders and shrink-fit chucks used in CNC machining centers and manual mills. The micrograin carbide substrate supports feeds and speeds appropriate for high-hardness workpiece materials including superalloys and hardened steels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentrations and extends tool life on internal radii\u003c\/li\u003e\n\u003cli\u003eWXL PVD coating improves wear resistance across steel, stainless steel, cast iron, non-ferrous metals, superalloys, and hard materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design permits direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction with normal pitch for predictable chip evacuation\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 4 helical flutes handles both roughing and finishing material removal\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard collet-style toolholders accepting a 1\/4 inch straight cylindrical shank.

Ensure the toolholder bore is clean and free of chips before seating the shank. Shank diameter tolerance is h6; verify collet or chuck runout is within acceptable limits to avoid premature edge wear. Follow the machine tool manufacturer and OSG cutting data recommendations when setting speeds and feeds for the specific workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\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\u003eCoating\u003c\/strong\u003e: WXL (PVD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eShank Type\u003c\/strong\u003e: Straight Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: 0.0000 to -0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Non-Ferrous Metal, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3670\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 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: OSG\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 36701511\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"OSG","offers":[{"title":"Default Title","offer_id":51728149184818,"sku":"36701511","price":89.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b02b0b6fa7a2bd37e314ecf4c963fdd2.jpg?v=1788688816","url":"https:\/\/voomisupply.com\/products\/osg-36701511-corner-radius-end-mill-1-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
