It features a 1\/4 inch diameter, a 0.031 inch corner radius, and four flutes with a variable helix and variable index geometry. The FIREX coating provides heat and wear resistance for extended tool life when cutting steel, cast iron, stainless steel, superalloys, titanium, and hard materials. With a 3\/4 inch length of cut and 2.5 inch overall length, this single-end tool is sized for typical finishing and roughing passes in both manual and CNC setups. It is installed by machinists and CNC operators in production and job shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for both roughing and finishing operations in ferrous and difficult-to-machine materials including steel, cast iron, stainless steel, superalloys, titanium, and hard materials. The corner radius geometry reduces stress concentration at the cutting edge compared to a square end mill, making it a practical choice for slotting, profiling, and pocket milling where edge chipping is a concern. The straight-cylindrical shank fits standard end mill holders used in CNC machining centers and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hard material applications\u003c\/li\u003e\n  \u003cli\u003eFIREX coating for elevated heat resistance and extended tool life\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index geometry reduces chatter and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e0.031 inch corner radius with a tight tolerance of -0.002 to 0.002 inches\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute direction with centercutting capability for versatile entry paths\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard end mill holders via 1\/4 inch straight-cylindrical shank\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders.

Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in the end mill holder and torque the retention mechanism per the holder manufacturer specifications. Confirm runout with a dial indicator before beginning a cut, particularly when working with tight-tolerance corner radius requirements.\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\u003eCorner Radius\u003c\/strong\u003e: 0.031 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: -0.002 to 0.002 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: 3\/4 inch (0.7500 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: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: Yes\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\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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 Material\u003c\/strong\u003e: Steel, Cast Iron\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel, Superalloys and Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: h10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 3079\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: GUHRING\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9030790063540\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51749518246194,"sku":"9030790063540","price":78.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b60c4e5299e23e28da7d9252082b4f3d_616964ad-3bff-4d91-9697-ce1a8583ebc0.jpg?v=1788907117","url":"https:\/\/voomisupply.com\/products\/guhring-9030790063540-corner-radius-end-mill-1-4-in-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
