It features a 1\/2 inch diameter, a 1 inch length of cut, and a 0.09 inch corner radius that blends the cutting edge to reduce stress concentrations and extend tool life in slotting, profiling, and contouring applications. The 40-degree helix angle promotes efficient chip evacuation, and the TiCN coating provides enhanced hardness and wear resistance compared to uncoated carbide. Micrograin carbide construction supports tight tolerances and consistent performance in ferrous and non-ferrous materials. This tool is installed by machinists and tool and die professionals in CNC milling operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in CNC machining centers and manual knee mills where corner radius geometry is required to produce radiused inside corners or to add strength to milled features. The single-end, centercutting design allows plunge entry as well as peripheral and slot milling. The long-length classification, 4 inch overall length with a 1\/2 inch shank, accommodates setups requiring additional reach while maintaining rigidity through the solid carbide construction. Right-hand cutting and right-hand flute spiral are standard for conventional CNC spindle direction.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e0.09 inch corner radius reduces stress risers and extends part and tool life in radiused-corner milling\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves surface hardness and wear resistance for longer run times in steel and alloy materials\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduces heat buildup\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction supports precise tolerances and resists chipping under high feed rates\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n  \u003cli\u003eSingle-end design with right-hand cut and right-hand spiral for standard CNC spindle compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/2 inch shank corner radius end mill compatible with CNC machining centers, vertical mills, and milling fixtures accepting 1\/2 inch collets or end mill holders.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified machinist or CNC operator. Ensure the spindle is fully stopped and the machine is in an energy-isolated state before loading or changing the tool. Seat the shank fully in a clean, undamaged collet or end mill holder and torque the retention nut according to the toolholder manufacturer specification. Inspect the corner radius and cutting edges for chips or damage before each use, and verify runout at setup to protect both the tool and the workpiece surface finish.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/2 inch (0.5000 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0900 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\/2 inch\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\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\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\u003eFlute Type\u003c\/strong\u003e: Spiral\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: 0.1 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12183569\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730932498738,"sku":"12183569","price":144.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c5d790c07b434f747ca4c287faa05af1.jpg?v=1788724986","url":"https:\/\/voomisupply.com\/products\/accupro-12183569-corner-radius-end-mill-1-2-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
