It features a 1 inch cutting diameter, a 1-3\/4 inch length of cut, and a 0.09 inch corner radius that blends floor-to-wall transitions and reduces stress concentrations at part corners. The tool is coated with AlTiN (aluminum titanium nitride) for elevated heat resistance and extended tool life in hardened steels and high-temperature alloys. With a 4 inch overall length and a 40-degree helix angle, it delivers efficient chip evacuation and smooth surface finishes. Machinists and CNC operators install this tool in vertical and horizontal machining centers.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits finish and semi-finish milling applications in mold and die work, aerospace components, and precision part manufacturing. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC setups. The micrograin carbide substrate provides toughness and edge retention when working ferrous and non-ferrous materials at high feed rates and surface speeds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.09 inch corner radius reduces stress risers and improves corner blending on finished surfaces\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for dry and semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide substrate delivers superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes efficient chip evacuation and reduces cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design enables direct plunge entry without a pre-drilled pilot hole\u003c\/li\u003e\n  \u003cli\u003e3 flutes balance chip clearance with cutting edge contact for finish milling passes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard-shank solid carbide corner radius end mill with a 1 inch shank diameter, compatible with ER, CAT, BT, and HSK toolholders sized for 1 inch straight shanks in CNC machining centers.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The machine spindle must be stopped and locked out before inserting or removing the tool from the holder. Ensure the toolholder collet or set-screw bore matches the 1 inch shank diameter and that the tool is seated to the proper gauge length before tightening. Inspect the cutting edges for chipping before each use; carbide end mills should not be forced into a worn or undersized bore.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 1-3\/4 inches\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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: AlTiN\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\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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\u003eVariable Index\u003c\/strong\u003e: No\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\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: 1.34 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12181886\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51734742565170,"sku":"12181886","price":468.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b002d9d9c9bd00b401cbda49963607f0.jpg?v=1788766459","url":"https:\/\/voomisupply.com\/products\/accupro-12181886-corner-radius-end-mill-1in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
