It features a 1\/4 inch diameter, a 1-1\/8 inch length of cut, and a 0.06 inch corner radius across 7 flutes. The extra-long 3 inch overall length and variable helix design reduce chatter and improve surface finish in deep-cavity and extended-reach applications. This is a single-end, centercutting tool intended for use by machinists and tool-and-die professionals working on CNC milling centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for finishing passes on steel, stainless steel, cast iron, superalloys, titanium, and hard materials. Its submicron carbide grade and close pitch configuration make it appropriate for high-precision work where tight tolerances and fine surface finishes are required. The straight-cylindrical shank with h6 tolerance mounts directly into standard end mill holders. Typical applications include contouring, profiling, and slot finishing in both production and job-shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute geometry increases feed rates and improves surface finish on finishing passes\u003c\/li\u003e\n  \u003cli\u003eVariable helix and variable index design reduce harmonic vibration and chatter\u003c\/li\u003e\n  \u003cli\u003e0.06 inch corner radius protects cutting edge and produces consistent corner geometry\u003c\/li\u003e\n  \u003cli\u003eExtra-long 3 inch OAL with 1-1\/8 inch LOC supports deep-cavity and extended-reach milling\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSubmicron solid carbide grade rated for steel, cast iron, superalloys, titanium, and hard materials\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with standard end mill holders accepting a 1\/4 inch straight-cylindrical shank with h6 tolerance.

Seat the shank fully into the end mill holder and torque the retention screw according to the holder manufacturer specification. Inspect the cutting edges and corner radius for chips or damage before each use. Do not exceed the tool manufacturer recommended speeds and feeds for the workpiece material being machined.\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 inch \/ 6.35 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\u003c\/strong\u003e: 1-1\/8 inch (1.0940 inch \/ 28.57 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inch (76.20 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inch \/ 6.35 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Tolerance\u003c\/strong\u003e: h6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Submicron Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Style\u003c\/strong\u003e: Variable\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePitch\u003c\/strong\u003e: Close\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Type\u003c\/strong\u003e: Straight-Cylindrical\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\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\u003eMaterial Removal Type\u003c\/strong\u003e: Finishing\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePrimary Workpiece Material\u003c\/strong\u003e: Steel, Cast Iron, Superalloys, Titanium, Hard Material\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSecondary Workpiece Material\u003c\/strong\u003e: Stainless Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 1040\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.07 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: GWS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 122893\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GWS","offers":[{"title":"Default Title","offer_id":52057980993842,"sku":"122893","price":169.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/42fa64a5556424c949d12bea0c4ac40a_c9e737ad-fd02-4ef1-abc2-8d6a353046b6.jpg?v=1790039329","url":"https:\/\/voomisupply.com\/products\/gws-122893-corner-radius-end-mill-1-4-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
