It features a 0.2187-inch mill diameter, a 0.015-inch corner radius, and four flutes with a variable helix angle ranging from 35 to 38 degrees. The AlTiN (ALtima) PVD coating improves heat resistance and tool life when cutting ferrous and exotic alloys. At 2.5 inches overall length with a 7\/16-inch length of cut, this single-end, centercutting tool is suited for both roughing and finishing operations on CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is rated for use on steel, stainless steel, cast iron, superalloys, and titanium. The short flute length and straight cylindrical shank make it well-suited for tight-tolerance profiling, slotting, and contouring passes where corner edge integrity is critical. It mounts in a standard toolholder accepting a 1\/4-inch shank diameter. The variable helix geometry helps reduce chatter and harmonic vibration during aggressive cuts, making it a practical choice for production environments handling difficult-to-machine materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015-inch corner radius reduces stress concentration and improves edge life on profiling cuts\u003c\/li\u003e\n\u003cli\u003eVariable helix angle (35 to 38 degrees) minimizes chatter in ferrous and superalloy materials\u003c\/li\u003e\n\u003cli\u003eAlTiN PVD coating (ALtima) provides thermal and oxidation resistance for dry or semi-dry cutting\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral for use with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eRated for roughing and finishing in a single tool across steel, stainless, cast iron, and titanium\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard toolholders accepting a 1\/4-inch straight cylindrical shank.

Confirm shank seating depth and toolholder runout before operation, as excessive runout accelerates flute wear on carbide tooling. Do not exceed the recommended depth-of-cut or feed rates for the workpiece material and machine rigidity. Carbide end mills are brittle and should not be used in machines with significant spindle play or inadequate rigidity.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.2187 inches (7\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches (1\/64 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: 0.4375 inches (7\/16 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: 0.25 inches (1\/4 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 to 38 degrees (variable)\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: AlTiN PVD (ALtima)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\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\u003eCoolant Through\u003c\/strong\u003e: No\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 Materials\u003c\/strong\u003e: Steel, Stainless Steel, Cast Iron, Superalloys and Titanium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0020 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: +0.00120 to -0.00120 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0003 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 177\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1 pound\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: M.A. FORD.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 17721812A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"M.A. FORD","offers":[{"title":"Default Title","offer_id":51742184931634,"sku":"17721812A","price":85.13,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c67ef2830979b35f23ca36fb32c33de4.jpg?v=1788835859","url":"https:\/\/voomisupply.com\/products\/m-a-ford-17721812a-corner-radius-end-mill-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
