It features a 3\/4 inch diameter, a 2-1\/4 inch length of cut, and a 0.045 inch corner radius that reduces stress concentration at the cutting edge and extends tool life in demanding materials. The 5 inch overall length and long-reach geometry make it suitable for deeper cavity and profile work. A TiCN coating provides increased surface hardness and lubricity for improved wear resistance. This tool is used by machinists and CNC operators working in job shops, production facilities, and toolrooms.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for side milling, slotting, and profiling operations in steel, stainless steel, cast iron, and other ferrous materials where corner radius geometry is required. The single-end, center-cutting configuration allows for both plunge entry and lateral cutting passes. The 40-degree helix angle promotes efficient chip evacuation and reduces chatter during full-depth passes. The right-hand flute direction and right-hand cutting direction are standard for conventional CNC machining center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.045 inch corner radius reduces edge chipping and stress risers on workpiece corners\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and wear resistance compared to uncoated carbide\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports higher feed rates and longer tool life\u003c\/li\u003e\n\u003cli\u003e4-flute, 40-degree helix design balances chip load and surface finish\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry without a pilot hole\u003c\/li\u003e\n\u003cli\u003eLong-length geometry at 5 inches OAL accommodates deep pocket and profile work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and standard tooling option for CNC machining centers and manual mills accepting a 3\/4 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 or CNC operator. Secure the 3\/4 inch shank in a matching end mill holder or collet to the appropriate pull-out force per machine tool manufacturer guidelines. Ensure the spindle and tool changer are fully stopped and the machine is in an E-stop or lockout state before inserting or removing the tool. Do not exceed the tool manufacturer recommended depth of cut or radial engagement for the material being machined.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches (1.6250 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0450 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\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\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 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\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\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\u003c\/strong\u003e: TiCN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Long\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: 1.04 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: 12183147\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51736949489970,"sku":"12183147","price":313.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f9746fe2f6c54f872d4ee9ff33bf1718.jpg?v=1788782282","url":"https:\/\/voomisupply.com\/products\/accupro-12183147-corner-radius-end-mill-3-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
