Built from micrograin solid carbide and coated with TiCN (Titanium Carbonitride), it delivers improved hardness and wear resistance compared to uncoated tooling. The 0.02 inch corner radius reduces stress concentration at the cutting edge, extending tool life in slotting, profiling, and pocketing applications. With a 1\/4 inch diameter, 4 flutes, and a 40-degree helix angle, this single-end centercutting tool is suited for finish and semi-finish cuts in ferrous and non-ferrous materials. Machinists and CNC operators working in job shops, tool rooms, and production environments are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is configured for right-hand cutting and right-hand flute direction, making it compatible with standard CNC machining centers and manual mills. The extra-long 6 inch overall length and 1-1\/2 inch length of cut provide extended reach for deep pockets and tall workpieces where standard-length tooling cannot reach. It is well suited for mold and die work, aerospace components, and general precision machining where controlled corner geometry is required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and edge retention\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces heat buildup at the cutting edge\u003c\/li\u003e\n\u003cli\u003e0.02 inch corner radius reduces chipping and stress at tool corners\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes smooth chip evacuation and reduces cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch OAL provides extended reach for deep-cavity applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-mount replacement or standard tooling selection for CNC machining centers and manual milling machines accepting a 1\/4 inch shank diameter collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing tooling. Use a properly sized collet or end mill holder that matches the 1\/4 inch shank diameter and torque the retention mechanism per the machine tool manufacturer specifications. Verify runout with a dial indicator before beginning production cuts to confirm proper seating and minimize premature tool wear.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.02 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\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: 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\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\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.00150 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.16 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: 12183647\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51727142650162,"sku":"12183647","price":88.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d5702321fcb73c1d329c3cbaaf21c1a_53908e1f-8c4f-4e66-a699-1a566e03f894.jpg?v=1788673958","url":"https:\/\/voomisupply.com\/products\/accupro-12183647-corner-radius-end-mill-1-4-in-4-flute-ticn","provider":"Voomi Supply","version":"1.0","type":"link"}
