It features a 1 inch cutting diameter, a 2.25 inch length of cut, and a 0.015 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding applications. With 4 flutes and a right-hand spiral flute direction, this end mill delivers efficient chip evacuation and smooth surface finishes. The bright\/uncoated finish and micrograin carbide substrate make it well suited for a range of ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC programmers in production and job shop environments.\u003c\/p\u003e\u003cp\u003eThis corner radius end mill is a single-end, centercutting tool with a 1 inch shank diameter and a 5 inch overall length, placing it in the long-length category. Its long reach makes it appropriate for deeper pockets, stepped cavities, and workpiece features that standard-length end mills cannot access. The 40-degree helix angle promotes smooth cutting action and helps manage heat buildup during extended cuts. It is suited for vertical machining centers, horizontal mills, and manual knee mills where a 1 inch straight shank is compatible with the spindle or tool holder in use.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with a 0.015 inch corner radius for edge strength and reduced chipping\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e4 right-hand spiral flutes with centercutting capability for plunge and ramp entry\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip flow and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eLong-length design at 5 inches OAL with 2.25 inch LOC for deep-pocket access\u003c\/li\u003e\n\u003cli\u003eBright\/uncoated finish suitable for use with or without cutting fluid\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide corner radius end mill for CNC and manual milling machines accepting a 1 inch straight shank tool holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis end mill should be installed by a qualified machinist following the tool holder manufacturer torque and runout specifications for 1 inch shank tooling. Inspect the shank and tool holder bore for contamination or damage before seating the tool. Verify spindle speed and feed rate parameters in the machining program before cutting. Always follow machine guarding requirements and wear appropriate personal protective equipment when operating milling equipment.\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\u003eLength of Cut\u003c\/strong\u003e: 2.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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\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\u003eWeight\u003c\/strong\u003e: 1.89 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: 12182970\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746701738290,"sku":"12182970","price":629.83,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/df8e637fa4be39b5fee415a08fc3bd4c.jpg?v=1788872989","url":"https:\/\/voomisupply.com\/products\/accupro-12182970-corner-radius-end-mill-1in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
