It features a 1\/4 inch diameter, a 3\/4 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 40-degree helix angle promotes efficient chip evacuation and smoother surface finishes. An AlTiN coating provides high-temperature hardness and oxidation resistance, making this tool well-suited for dry or near-dry machining at elevated cutting speeds. Machinists and tool and die professionals install this end mill in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is used in ferrous metal machining, die and mold work, and general-purpose profiling where a radiused corner is required to reduce part stress risers or meet print specifications. The centercutting geometry allows it to be plunged directly into the workpiece, giving it flexibility for slot milling, pocket milling, and ramping operations. It is a single-end tool with right-hand flute direction and right-hand cutting direction. The micrograin carbide substrate supports high rigidity and wear resistance across a range of steel and alloy applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.06 inch corner radius reduces edge chipping and part stress concentrations\u003c\/li\u003e\n\u003cli\u003eAlTiN coating provides high-temperature oxidation resistance for dry and high-speed machining\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and improved surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand spiral with 4 flutes for balanced cutting performance\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill for use in standard 1\/4 inch collet chucks, end mill holders, and compatible tooling systems on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolroom practices. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Seat the shank fully in a clean, undamaged collet or end mill holder and torque the retention hardware per the toolholder manufacturer specifications. Verify runout with an indicator before beginning a cut, and confirm cutting parameters against the workpiece material and machine capability.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/4 inch (0.2500 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\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (1.5000 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0600 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 Type\u003c\/strong\u003e: Corner Radius\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\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\u003eCoating\/Finish\u003c\/strong\u003e: AlTiN\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\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\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\u003eWeight\u003c\/strong\u003e: 0.12 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: 12182473\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749615993138,"sku":"12182473","price":46.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6ff70e06575ddef616f03740219ff757.jpg?v=1788908384","url":"https:\/\/voomisupply.com\/products\/accupro-12182473-corner-radius-end-mill-1-4-in-4-flute-altin","provider":"Voomi Supply","version":"1.0","type":"link"}
