It features a 1\/4 inch mill diameter, a 3\/4 inch length of cut, and a 0.09 inch corner radius that reduces stress concentration at the cutting edge and extends tool life compared to sharp-corner end mills. The 2-flute, right-hand spiral configuration promotes efficient chip evacuation, and the TiCN coating increases surface hardness and wear resistance. Overall length is 2.5 inches with a 1\/4 inch shank diameter. Micrograin carbide substrate provides the rigidity needed for demanding cuts.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for ferrous and non-ferrous machining applications including profiling, slotting, and contouring. The centercutting geometry allows plunge entry, making it practical for pocketing and ramp-entry operations. It is a single-end tool intended for CNC machining centers and manual mills where a radiused corner profile is required. The 40-degree helix angle improves cutting action and finish quality on harder materials. Typical users include machinists and tool-and-die shops working in job-shop and production environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.09 inch corner radius reduces edge chipping and extends tool life versus sharp-corner geometry\u003c\/li\u003e\n\u003cli\u003eTiCN coating for increased hardness, wear resistance, and performance on harder workpiece materials\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry and ramp interpolation\u003c\/li\u003e\n\u003cli\u003e2-flute right-hand spiral promotes open chip flow and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate delivers rigidity and dimensional stability\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle improves surface finish and cutting efficiency\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 1\/4 inch straight shank end mill with a 0.09 inch corner radius profile.\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 tolerance. Ensure the machine spindle is fully stopped and locked out before changing tooling. Use a properly sized collet or end mill holder to achieve the shank diameter tolerance range specified for this tool. Verify tool projection and stick-out are minimized to reduce deflection during cutting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.09 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.0015 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\u003c\/strong\u003e: 0.25 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\u003eOverall Length\u003c\/strong\u003e: 2.5 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\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\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: 0.06 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: 12181344\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51729184653618,"sku":"12181344","price":55.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/56053390cc89fda5efbdaa78b3d55f38.jpg?v=1788701594","url":"https:\/\/voomisupply.com\/products\/accupro-12181344-corner-radius-end-mill-1-4-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
