It features a 1 inch cutting diameter, a 2.25 inch length of cut, and a 0.09 inch corner radius that reduces stress concentrations at the tool tip and extends tool life in aggressive roughing and finishing passes. The AlTiN coating provides excellent thermal resistance and hardness at elevated cutting temperatures. With 4 spiral flutes in a right-hand cutting direction, this single-end, centercutting design is suited for slotting, profiling, and plunge operations. Machinists and CNC operators in job shops, aerospace, and general machining environments rely on this geometry for consistent, repeatable results.\u003c\/p\u003e\u003cp\u003eThis end mill is built for use in CNC machining centers and manual mills where tight tolerances and surface finish consistency are critical. The long-length configuration with a 6 inch overall length and 1 inch shank diameter makes it well suited for reaching into deep pockets and cavities without sacrificing rigidity. It is appropriate for dry or minimum-quantity lubrication cutting strategies where the AlTiN coating manages heat effectively. Applications include profiling hardened tool steel, machining titanium alloys, and finishing stainless steel components where a corner radius geometry is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1 inch cutting diameter with 0.09 inch corner radius for reduced notch wear and improved surface finish at part edges\u003c\/li\u003e\n\u003cli\u003eAlTiN coating for high-temperature hardness and extended tool life in ferrous and exotic alloys\u003c\/li\u003e\n\u003cli\u003e4 spiral flutes with right-hand cutting direction for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSingle-end, centercutting design supports plunge entry cuts\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate for increased rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003eLong-length geometry with 6 inch OAL suitable for deep-pocket reach applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for CNC machining centers and manual mills accepting a 1 inch straight shank end mill holder or collet chuck.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state. Use a properly rated end mill holder or collet chuck sized for the 1 inch shank diameter and torque the retention mechanism according to the toolholder manufacturer specifications. Inspect the shank and collet bore for chips or contamination before seating the tool. Tool projection and runout should be verified with a dial indicator before initiating a cutting program.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 inch\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\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\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: Long\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.0015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0000 to -0.0025 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: 2.51 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: 12183446\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730551636274,"sku":"12183446","price":719.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/abd029383cb45bec3e1c2ff93622923f.jpg?v=1788719439","url":"https:\/\/voomisupply.com\/products\/accupro-12183446-corner-radius-end-mill-1-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
