It carries a 5\/16-inch mill diameter, five helical flutes, and a 0.02-inch corner radius that blends the floor and wall of a cut to reduce stress concentrations and extend tool life. The nano-A coating provides a hard, low-friction surface that resists heat and built-up edge when cutting steel, stainless steel, cast iron, superalloys, and titanium. With a 7\/16-inch length of cut and a 2-inch overall length, this is a short, rigid tool well suited to stable setups where runout control is critical. Licensed machinists and CNC tooling specialists are the primary users.\u003c\/p\u003e\n\u003cp\u003eThis end mill is designed for both roughing and finishing passes in a single setup, reducing tool changes in production environments. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Secondary applications cover non-ferrous metals and hard materials. The right-hand cut and right-hand helix suit conventional CNC machining center spindles. The straight-cylindrical shank mounts directly in standard end mill holders. Series 6985 tools are categorized as short-length geometry, favoring rigidity over reach in tight-tolerance work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for maximum rigidity and wear resistance in hard materials\u003c\/li\u003e\n  \u003cli\u003enano-A coating reduces friction and heat buildup in steel, stainless, and superalloy cuts\u003c\/li\u003e\n  \u003cli\u003e0.02-inch corner radius reduces stress cracking at part edges and extends insert life at the cutter tip\u003c\/li\u003e\n  \u003cli\u003eFive-flute configuration increases feed rate capacity compared to three- or four-flute tools of the same diameter\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and medium-high helix style for efficient chip evacuation in ferrous materials\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with straight-cylindrical shank for direct mounting in end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders.

Secure the straight-cylindrical shank in a clean, undamaged end mill holder and torque to the holder manufacturer specification before running. Verify runout at the cutting tip before beginning a cut, as carbide end mills at this diameter are sensitive to holder concentricity. Do not use this tool in a drill chuck or set-screw collet not rated for milling side loads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 7\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 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\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 inches (0.3125 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: nano-A\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Medium 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\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, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Non-Ferrous Metal, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\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\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 6985\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\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 9069850079420\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51738638057778,"sku":"9069850079420","price":110.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/26a1dbb5c68d0ef073c98415f19a1058_47b0fc46-55b0-4a9c-abf9-675799bd268c.jpg?v=1788802186","url":"https:\/\/voomisupply.com\/products\/guhring-9069850079420-corner-radius-end-mill-5-16in-5-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
