It features a 1\/2 inch mill diameter, a 1 inch length of cut, and a 0.045 inch corner radius that reduces stress concentrations at the tool tip and extends tool life compared to sharp-corner geometries. The 4-flute, single-end design with a 40-degree right-hand helix promotes efficient chip evacuation and smooth surface finishes. A TiCN coating adds surface hardness and wear resistance for use in ferrous and non-ferrous materials. Machinists and CNC tool room operators are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slot milling, peripheral milling, and profiling operations on machining centers and CNC mills. The long-length classification, 4 inch overall length, and centercutting capability allow it to plunge directly into the workpiece and reach deeper features. The micrograin carbide substrate supports higher cutting speeds and feeds in hardened steels, stainless steels, cast iron, and aluminum alloys. It is appropriate for both job shop and production environments where tight tolerances and repeatable surface quality are required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.045 inch corner radius reduces chipping and improves surface finish at step transitions\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides enhanced wear resistance and surface hardness for ferrous and non-ferrous cutting\u003c\/li\u003e\n\u003cli\u003e4-flute spiral configuration with 40-degree helix angle promotes chip flow and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports high cutting speeds and extended tool life\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and right-hand cutting compatible with standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting 1\/2 inch straight shank end mills.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and the tool changer or collet is de-energized before inserting or removing the tool. Use a properly sized ER or DA collet, or a side-lock holder rated for the 1\/2 inch shank diameter, and verify runout with a dial indicator before initiating a cut. Do not exceed the tool manufacturer's recommended cutting parameters for the workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.045 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: TiCN\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: Spiral\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 End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.06 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: ACCUPRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 12183567\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731935297842,"sku":"12183567","price":144.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2b38ba9a5f9062e0c58e54039502da91.jpg?v=1788736872","url":"https:\/\/voomisupply.com\/products\/accupro-12183567-corner-radius-end-mill-1-2-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
