It features a 1\/4 inch cutting diameter, a 1 inch length of cut, and a 0.06 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. The TiCN coating adds surface hardness and lubricity, improving performance in abrasive materials. With four right-hand spiral flutes and a 40-degree helix angle, this single-end, centercutting tool is suited for slotting, profiling, and plunge cuts in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in machine shops, tool rooms, and manufacturing environments where tight tolerances and consistent surface finishes are required. The long-length configuration and 4 inch overall length provide additional reach for deep-pocket and cavity work. The micrograin carbide substrate supports high cutting speeds and feeds while maintaining edge integrity. It is installed by machinists and CNC programmers in environments ranging from job shops to production floor operations.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1\/4 inch cutting diameter with a 0.06 inch corner radius for reduced edge chipping and improved part finish\u003c\/li\u003e\n\u003cli\u003eTiCN coating for enhanced hardness and wear resistance in abrasive materials\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes at a 40-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for dimensional stability and long tool life\u003c\/li\u003e\n\u003cli\u003eSingle-end configuration with 4 inch overall length for extended reach in deep-cavity applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit option for standard 1\/4 inch shank collets and tool holders used in CNC machining centers and manual milling machines accepting ER or straight-shank tooling.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes should be performed by a qualified machinist with the spindle fully stopped and the machine in a locked-out, de-energized state. Ensure the collet and tool holder bore are clean and free of chips before seating the shank. Confirm runout with a dial indicator after clamping to maintain tolerance integrity. Follow the machine tool manufacturer guidelines for appropriate clamping torque on the collet nut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCutting Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (3.1250 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\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\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 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: 12183485\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51728851697970,"sku":"12183485","price":78.87,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c9b5ec1a0ffdbd8c4fb431cc080711b7.jpg?v=1788696861","url":"https:\/\/voomisupply.com\/products\/accupro-12183485-corner-radius-end-mill-1-4-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
