Built to Series 2215 specs, it features a 3\/8 inch diameter, 7 flutes, and a 0.03 inch corner radius that reduces edge chipping and improves surface finish on workpiece corners. The AlCr-based FX3 coating provides thermal and oxidation resistance suited for hard and abrasive materials. This single-end, centercutting tool is intended for use with standard end mill holders and is installed by machinists and CNC programmers operating milling machines in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for finishing passes in steel, stainless steel, superalloys, titanium, and cast iron applications. The 7-flute, close-pitch configuration allows for higher feed rates per revolution while maintaining a quality surface finish. The 1 inch length of cut (LOC) and 2.5 inch overall length (OAL) make it well-suited for standard-depth finishing in vertical and horizontal milling setups. Right-hand flute direction and right-hand cutting direction are standard for conventional milling machine spindles. No coolant-through capability is present, so external coolant or air blast is the appropriate cooling method for this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces stress concentration and extends tool life on steel and stainless steel workpieces\u003c\/li\u003e\n\u003cli\u003e7-flute close-pitch design supports high feed rates during finishing passes\u003c\/li\u003e\n\u003cli\u003eFX3 AlCr coating provides oxidation and heat resistance for hard and abrasive materials\u003c\/li\u003e\n\u003cli\u003eSolid submicron carbide grade delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows plunge entry as well as peripheral milling\u003c\/li\u003e\n\u003cli\u003eStraight-cylindrical shank with h6 tolerance for precise fit in end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard end mill holders accepting a 3\/8 inch straight-cylindrical shank.

Secure the shank fully in a compatible end mill holder to the depth recommended by the holder manufacturer, and verify runout before beginning a cut. Confirm spindle direction is set to right-hand rotation before engaging the tool. Do not exceed the rated LOC of 1 inch, and use appropriate external coolant or air blast since this tool has no coolant-through provision.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches \/ 9.53 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1 inch (25.40 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 2.5 inches (63.50 mm)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: 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\u003eHelix Style\u003c\/strong\u003e: High\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide (Submicron Grade)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FX3 (AlCr)\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\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Cast Iron\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 2215\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.18 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: GWS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 312589\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":51972173398322,"sku":"312589","price":123.61,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/73a005d5ba50d83229d91438d40f4ca3_566ed5d4-1afa-4da9-a8b7-514b17355e6a.jpg?v=1789963675","url":"https:\/\/voomisupply.com\/products\/gws-312589-corner-radius-end-mill-3-8-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
