Built to Series 6986 specifications, it features a 1\/4 inch mill diameter, five helical flutes, and a 0.02 inch corner radius that extends tool life and reduces chipping at the cutting edge. The nano-A coating provides enhanced wear resistance and thermal stability during dry or wet cutting operations. This is a single-end tool with a right-hand cutting direction and right-hand flute direction. It is sized for use with standard end mill holders and suits both roughing and finishing passes on steel, stainless steel, cast iron, superalloys, and titanium.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills where close-tolerance contouring and peripheral milling are required. The 0.02 inch corner radius makes it appropriate for parts that require a small but defined blend radius at the bottom of a pocket or shoulder. Primary workpiece materials include steel, stainless steel, cast iron, superalloys, and titanium. Secondary applications cover non-ferrous metals and hard materials. The straight-cylindrical shank seats directly in end mill holders without adapters. This tool is typically installed and used by machinist tradespeople and CNC setup technicians in job shops, production facilities, and maintenance machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in ferrous and superalloy cutting\u003c\/li\u003e\n\u003cli\u003enano-A coating provides improved hardness and oxidation resistance at elevated cutting temperatures\u003c\/li\u003e\n\u003cli\u003eFive helical flutes with normal pitch and medium-high helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius with a tight tolerance of -0.002 to 0.002 inches for consistent blend radii\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute direction; single-end configuration for standard toolpath programming\u003c\/li\u003e\n\u003cli\u003eCompatible with end mill holders; straight-cylindrical shank with h6 shank diameter tolerance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with end mill holders.

Before mounting or changing tooling, ensure the machine spindle is fully stopped and the control is in a safe state. Seat the shank fully into the end mill holder and torque the retention mechanism according to the holder manufacturer specifications. Verify runout with a dial indicator before commencing a cut, as excessive runout will accelerate edge wear on carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches (1\/4 inch)\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: 0.5 inches (1\/2 inch) nominal; 1.4961 inches decimal\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 (1\/4 inch)\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\u003eHelix Angle\u003c\/strong\u003e: 38 degrees, medium-high style\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Helical\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\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\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\u003eMaterial Removal Type\u003c\/strong\u003e: Roughing and Finishing\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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\u003eSeries\u003c\/strong\u003e: 6986\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: End Mill Holders\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 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: 9069860063520\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GUHRING","offers":[{"title":"Default Title","offer_id":51748160471346,"sku":"9069860063520","price":107.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f809395be4178c60f6ffd0070b106959.jpg?v=1788889796","url":"https:\/\/voomisupply.com\/products\/guhring-9069860063520-corner-radius-end-mill-1-4-in","provider":"Voomi Supply","version":"1.0","type":"link"}
