It features a 1\/4 inch mill diameter, a 3\/4 inch length of cut, and a 0.06 inch corner radius for consistent edge blending and reduced stress concentration at part corners. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. A TiCN coating adds surface hardness and wear resistance, extending tool life in ferrous and non-ferrous materials. This tool is installed and operated by machinists and CNC programmers on vertical machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish milling, profiling, and contouring applications where a radiused corner is required. The centercutting geometry allows for plunge entry as well as standard peripheral cuts. Its single-end, right-hand cut and right-hand flute direction make it compatible with conventional milling setups. The 2-flute configuration provides wider chip clearance, making it a practical choice for slotting and pocketing in softer metals and plastics as well as light cuts in harder alloys.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.06 inch corner radius reduces stress risers and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides enhanced hardness and wear resistance over uncoated carbide\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth cutting forces\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute direction for standard spindle operation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use corner radius end mill for standard 1\/4 inch collet or end mill holders on vertical machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following the machine tool manufacturer guidelines for tool holding and runout. Ensure the spindle is fully stopped and the machine is in a safe state before changing tooling. Use a properly sized collet or end mill holder matched to the 1\/4 inch shank diameter, and confirm tool projection and runout with a dial indicator before beginning a cut. Follow applicable shop safety standards for rotating cutting tools, including appropriate guarding and PPE.\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 (0.7500 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: 0.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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 Type\u003c\/strong\u003e: Spiral\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\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\u003eEnd Mill Material\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\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: 12181343\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740373254450,"sku":"12181343","price":49.76,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2a4e2eab1e7c387565f18b3a963298d0.jpg?v=1788824594","url":"https:\/\/voomisupply.com\/products\/accupro-12181343-corner-radius-end-mill-1-4-in-2-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
