With a 1 inch cutting diameter, a 0.03 inch corner radius, and a TiCN (Titanium Carbonitride) coating, this tool delivers extended tool life and wear resistance in demanding machining environments. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. It is a single-end, centercutting design, meaning it can be plunged directly into a workpart. Machinists and tool-and-die professionals install this tool in CNC machining centers and milling machines for profiling, slotting, and contouring operations.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for production and job-shop milling applications where a controlled edge radius is required to reduce stress concentrations in machined pockets and profiles. The right-hand flute direction and right-hand cutting geometry are compatible with standard CNC spindle configurations. The 1-3\/4 inch length of cut accommodates moderate-depth passes, while the 4 inch overall length provides adequate clearance for most standard setups. This tool is appropriate for use in aerospace, mold-and-die, and general precision machining applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for improved hardness and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating provides high surface hardness and reduced friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces chipping and stress concentration in milled corners\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip evacuation and surface finish in a range of materials\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tooling option for CNC machining centers and manual milling machines accepting a 1 inch straight shank end mill with standard ER or end mill holder collet systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool is installed by a machinist or toolroom technician using an appropriate end mill holder or collet chuck rated for 1 inch shank tooling. Ensure the machine spindle is fully stopped and locked out before changing tooling. Follow the machine tool manufacturer torque specifications for the collet nut or set-screw holder. Verify runout at the cutting edge after installation before beginning a cut.\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: 1.75 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: 0.03 inch\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: TiCN\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002500 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.34 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: 12181874\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731962200370,"sku":"12181874","price":466.33,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/51ebc22bf876bf7a3e23f877e05fcd56.jpg?v=1788737299","url":"https:\/\/voomisupply.com\/products\/accupro-12181874-corner-radius-end-mill-1in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
