It features a 5\/8-inch cutting diameter, a 1-1\/4-inch length of cut, and a 0.031-inch corner radius that reduces stress concentrations and extends tool life at part transitions. The 6-flute, right-hand helical geometry with a close pitch and high helix angle promotes smooth chip evacuation and superior surface finish. A FIREX coating provides thermal and oxidation resistance, making this tool well-suited for demanding cutting environments. Machinists and tool-and-die professionals use this end mill in CNC machining centers with standard end mill holders.\u003c\/p\u003e\u003cp\u003eThis end mill is built for finishing passes in steel, stainless steel, cast iron, superalloys, titanium, non-ferrous metals, and hard materials. Its single-end, straight-cylindrical shank design fits directly into standard end mill holders. The 3-1\/2-inch overall length provides adequate reach for most milling setups without sacrificing rigidity. It is not centercutting, so it is intended for side milling, profiling, and contour finishing rather than direct plunge operations. The Series 3091 designation places it within a consistent GUHRING tooling family for repeat ordering and system compatibility.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.031-inch corner radius reduces tool stress and improves part surface quality at edges\u003c\/li\u003e\n\u003cli\u003eFIREX coating provides high thermal resistance for extended tool life in tough alloys\u003c\/li\u003e\n\u003cli\u003e6-flute close-pitch geometry optimized for finishing cuts with fine surface finishes\u003c\/li\u003e\n\u003cli\u003eHigh helix angle promotes efficient chip flow in deep-pocket and contour applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eSolid carbide construction delivers rigidity and wear resistance across a broad material range\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible with standard end mill holders.

Ensure the machine spindle is fully stopped and locked out before mounting or removing the tool from the holder. Secure the straight-cylindrical shank to the specified clamping torque of the end mill holder manufacturer. Verify runout with a dial indicator before beginning cuts, as excessive runout on a 6-flute finisher will rapidly degrade surface quality and tool life.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 6\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.25 inches (0.7500 inches decimal per supplier data)\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: -0.02 to 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: High\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\u003eCoating\u003c\/strong\u003e: FIREX\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\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\u003eSeries\u003c\/strong\u003e: 3091\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\u003ePrimary Workpiece Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys, Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Materials\u003c\/strong\u003e: Non-Ferrous Metal, Hard Material\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 0.75 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: GUHRING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 9030910158740\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51732024262962,"sku":"9030910158740","price":326.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d36d7e56e27d5edff2a7735007763096_f3b1ac06-166d-4328-b64a-31d30a3af99f.jpg?v=1788738269","url":"https:\/\/voomisupply.com\/products\/guhring-9030910158740-corner-radius-end-mill-5-8-in-6-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
