It features a 3\/4 inch diameter, a 1-1\/2 inch length of cut, and a 0.0200 inch corner radius that reduces stress concentrations at part edges and extends tool life in demanding cuts. The 4-flute, right-hand spiral geometry combined with a TiCN coating provides excellent wear resistance and performance in harder ferrous materials. At 4 inches overall length with a matching 3\/4 inch shank diameter, this single-end, centercutting tool handles both plunge and contour operations. It is intended for use by machinists and CNC operators working in production or job-shop environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling slots, pockets, and profiles in steel, stainless steel, cast iron, and similar materials where a radiused corner is required for part geometry or fatigue resistance. The 40 degree helix angle promotes smooth chip evacuation and reduces chatter during high-feed passes. The micrograin carbide substrate supports sharp edge retention at elevated cutting temperatures. Typical applications include die and mold work, aerospace component machining, and general precision part production on CNC machining centers and manual knee mills.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for rigidity and edge retention\u003c\/li\u003e\n  \u003cli\u003eTiCN coating improves wear resistance in ferrous and abrasive materials\u003c\/li\u003e\n  \u003cli\u003e0.0200 inch corner radius reduces edge chipping and stress concentrations\u003c\/li\u003e\n  \u003cli\u003e4-flute right-hand spiral design supports high material removal rates\u003c\/li\u003e\n  \u003cli\u003e40 degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting capability allows direct plunge entry into workpiece\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct fitment corner radius end mill for CNC machining centers and manual mills accepting a 3\/4 inch straight shank toolholder.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eThis tool is installed and serviced by qualified machinists or CNC setup technicians. Ensure the spindle is fully stopped and machine is in an energy-isolated state before changing tooling. Seat the 3\/4 inch shank fully into a clean, properly torqued collet or end mill holder to prevent runout. Verify corner radius and diameter tolerances against job print requirements before beginning a production run.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inch (1.5000 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 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.0200 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\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000000 \/ -0.002500 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 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\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 (Micrograin)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating \/ Finish\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: 1 pound\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12182668\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51746897953074,"sku":"12182668","price":245.28,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/257288e3889a2b034ba72301d2536588.jpg?v=1788874440","url":"https:\/\/voomisupply.com\/products\/accupro-12182668-corner-radius-end-mill-3-4in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
