It features a 1\/8 inch cutting diameter, a 0.02 inch corner radius, and a TiCN (Titanium Carbonitride) coating that improves wear resistance and tool life in ferrous and non-ferrous materials. With four flutes and a 40-degree helix angle, this end mill promotes efficient chip evacuation and a smooth surface finish. The micrograin carbide substrate provides rigidity and edge retention during demanding cuts. It is a single-end, centercutting tool, meaning it can be used for plunge and ramp entry as well as peripheral and slot milling.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for CNC machining centers and manual mills handling precision contouring, profiling, and finishing passes. The corner radius geometry reduces stress concentration at the cutting edge, making it appropriate for hardened steels, stainless, and alloy materials where sharp corner breakdown is a concern. The stub length classification provides added rigidity, minimizing deflection during high-feed operations. Machinists, toolroom operators, and CNC programmers working in job shops, production facilities, and mold-and-die environments will find this a reliable single-use or re-grindable option depending on shop practice.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius reduces edge chipping and stress at cutting corners\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and lubricity for extended tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eFour-flute, right-hand spiral design with 40-degree helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCentercutting construction allows plunge milling and ramp entry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and sharpness retention\u003c\/li\u003e\n\u003cli\u003eStub length geometry minimizes deflection in tight-clearance setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style solid carbide corner radius end mill suitable for use in standard 1\/8 inch collets and end mill holders on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the 1\/8 inch shank fully and evenly in a clean, undamaged collet or tool holder and torque the drawbar or retention mechanism per the machine manufacturer specification. Verify runout with a dial indicator before beginning a production run, as excessive runout accelerates edge wear on small-diameter carbide tooling.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut (LOC)\u003c\/strong\u003e: 1\/4 inch (0.3750 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length (OAL)\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\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\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 End\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: Stub\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 12182727\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727516434738,"sku":"12182727","price":27.17,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/468326e6f277c3aa370abeaf747ac06b.jpg?v=1788678794","url":"https:\/\/voomisupply.com\/products\/accupro-12182727-corner-radius-end-mill-1-8-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
