It features a 3\/4 inch diameter with a 0.03 inch corner radius that reduces stress concentrations and extends tool life at the cutting edge. The 3-flute, right-hand spiral geometry with a 35-degree helix angle provides efficient chip evacuation and smooth cutting action. A TiCN coating adds surface hardness and lubricity, making it well suited for harder workpiece materials. This tool is single-end and centercutting, allowing plunge entry as well as standard peripheral and slot milling. It is installed and operated by machinists and CNC programmers in job shop and production machining settings.\u003c\/p\u003e\u003cp\u003eThis end mill is used in milling applications where a small corner radius is required to blend floor-to-wall transitions, reduce tool chatter, or meet part print radius callouts. Its 1-5\/8 inch length of cut and 4 inch overall length make it appropriate for moderate-depth pockets and slots in ferrous and non-ferrous materials. The micrograin carbide substrate supports higher cutting speeds and feeds compared to standard carbide grades. It is a strong fit for CNC vertical machining centers and manual knee mills running steel, stainless, cast iron, and similar materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and improves surface finish at part corners\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves wear resistance and performance in harder materials\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral design promotes efficient chip removal and reduces heat buildup\u003c\/li\u003e\n\u003cli\u003e35-degree helix angle provides smooth cutting action and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports tighter tolerances and longer tool life\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 3\/4 inch collets, end mill holders, or shrink-fit toolholders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Ensure the shank is fully seated and properly torqued in the toolholder before operation. Verify spindle speed, feed rate, and depth of cut against the material being machined before starting the cut. Inspect the cutting edges for wear or chipping before each use and replace the tool if damage is observed.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.03 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 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: 3\/4 inches\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: 35 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 to -0.002000 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: 0.75 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: 12179691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742247813426,"sku":"12179691","price":97.02,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6e9e569efc37de99c10c8e8a6b062201_bbae1a8c-4205-4a3f-934d-b38920e99fe7.jpg?v=1788836184","url":"https:\/\/voomisupply.com\/products\/accupro-12179691-corner-radius-end-mill-3-4-in-3-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
