It features a 1\/4 inch diameter, a 0.02 inch corner radius, and a TiCN (titanium carbonitride) coating that extends tool life in abrasive cutting conditions. With 4 flutes and a 40-degree helix angle, it delivers efficient chip evacuation and smooth surface finishes. The micrograin carbide substrate provides the rigidity needed for long-reach profiling and finishing passes. This is a single-end, centercutting tool, meaning it can be plunged directly into the workpiece. Machinists and tool-and-die professionals install this type of end mill on CNC machining centers and manual knee mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for finish profiling, slotting, and contouring operations where a radiused corner is required to reduce stress concentrations or meet part print callouts. The long flute length of 1-1\/8 inches supports deep-wall finishing in molds, dies, and precision machined components. The right-hand cut and right-hand spiral flute configuration are standard for conventional and climb milling on vertical machining centers. The 3 inch overall length and 1\/4 inch shank make it compatible with standard 1\/4 inch collets and end mill holders.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.02 inch corner radius reduces stress concentrations and meets radiused corner callouts\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and wear resistance in abrasive and ferrous materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate provides rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation and smooth finishes\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eLong flute length of 1-1\/8 inches supports deep-wall profiling and finishing\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 and end mill holders on CNC and manual vertical machining centers.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or toolroom professional. Ensure the spindle is fully stopped and the machine is locked out before changing tooling. Seat the shank fully in the collet or holder to the recommended grip length before torquing the retention nut. Verify runout at the cutting edge with a dial indicator before beginning production cuts.\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: 1-1\/8 inches (2.0000 inches decimal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 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 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\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\u003eLength Type\u003c\/strong\u003e: Long\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\u003eWeight\u003c\/strong\u003e: 0.14 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: 12183008\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744616808754,"sku":"12183008","price":71.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f48520528b91860eebecb1aff365681b.jpg?v=1788859050","url":"https:\/\/voomisupply.com\/products\/accupro-12183008-corner-radius-end-mill-1-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
