With a 1-inch mill diameter, a 3-inch length of cut, and a 0.06-inch corner radius, this tool produces smooth, radiused edges on pockets, slots, and contoured surfaces. The 4-flute, right-hand spiral design with a 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide with a bright, uncoated finish, it is suited for machinists and toolroom professionals working on CNC mills and manual machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is used in production and toolroom environments where an extra-long reach is required. The single-end, centercutting configuration allows plunge cutting and full-slot milling. The 6-inch overall length and 1-inch shank diameter make it appropriate for deep-cavity work and applications where standard-length tools cannot reach the workpiece. It fits collet chucks, end mill holders, and hydraulic toolholders sized for a 1-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1-inch mill diameter with 0.06-inch corner radius for radiused edge finishing\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with 40-degree helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for wear resistance and rigidity\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch overall length for deep-cavity and extended-reach applications\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge entry cuts\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for a range of base materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual mills accepting a 1-inch straight shank end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Ensure the spindle is fully powered down and locked out before loading or removing the tool. Confirm the tool holder bore and collet are clean and free of chips before seating the shank. Verify runout with a dial indicator after installation and before engaging the workpiece.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\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: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 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 Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0025 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: 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 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: 12183166\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749432361266,"sku":"12183166","price":592.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/675619cd4d59abc745738f8fab64fbe8.jpg?v=1788906025","url":"https:\/\/voomisupply.com\/products\/accupro-12183166-corner-radius-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
