Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), this single-end, center-cutting tool delivers wear resistance and edge stability in demanding cutting environments. The 0.03 inch corner radius reduces stress concentration at the cutting edge, extending tool life in slotting, profiling, and contouring operations. With a 40-degree helix angle and right-hand cutting direction, it generates efficient chip evacuation and smooth surface finishes. This is an extra-long configuration with a 6 inch overall length, suited for reaching deep features or tall workpiece geometry.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for ferrous and nonferrous metal stock removal. The extra-long reach and 1-1\/2 inch length of cut make it well suited for deep-cavity milling, multi-pass profiling, and finishing passes on mold, die, and fixture work. The TiCN coating performs well on cast iron, alloy steels, stainless, and hardened materials. Machinists and tool-and-die professionals working in job shops, production facilities, and aerospace or automotive machining environments are the primary users of this tool.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide substrate for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves hardness and wear resistance vs. uncoated carbide\u003c\/li\u003e\n\u003cli\u003e0.03 inch corner radius reduces edge chipping and stress concentration\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth cutting and efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting geometry allows plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch OAL with 1\/2 inch shank for deep-reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling selection for CNC machining centers and manual milling machines that accept a 1\/2 inch shank diameter end mill holder, collet chuck, or shrink-fit toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation of end mills should be performed by a qualified machinist following the machine tool manufacturer's toolholder torque and runout specifications. Always ensure the machine spindle is fully stopped and locked out before changing tooling. Verify shank-to-holder contact length meets minimum engagement requirements for the holder type in use. Inspect the cutting edges and corner radius under magnification before use to confirm no shipping damage is present.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5 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: 1.25 inches (1-1\/2 inches nominal)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5 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\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 Tolerance\u003c\/strong\u003e: -0.0001 to -0.0004 inches\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\u003eLength Type\u003c\/strong\u003e: Extra Long\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\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.63 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: 12183731\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730443796786,"sku":"12183731","price":225.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6004a997eb88a51663c8f78fd96ec8d.jpg?v=1788717567","url":"https:\/\/voomisupply.com\/products\/accupro-12183731-corner-radius-end-mill-1-2-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
