It features a 1\/16 inch (0.0625 inch) mill diameter with a 0.015 inch corner radius and a TiCN (Titanium Carbonitride) coating that improves hardness and wear resistance at the cutting edge. The four-flute, right-hand spiral configuration handles center cutting, allowing direct plunge entry into the workpiece. With a 3\/16 inch length of cut and 1-1\/2 inch overall length, this tool is sized for fine detail work in production and toolroom environments. Machinists and CNC operators working with hardened steels, stainless, and high-temp alloys will find the micrograin carbide substrate and TiCN finish well suited to demanding feed and speed requirements.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC vertical machining centers, manual mills, and tool-and-die applications where a controlled corner radius is required to reduce stress concentrations in pocketed features and profiled slots. The single-end, centercutting design supports ramping, helical interpolation, and direct plunge entry. The 1\/8 inch shank diameter fits standard collet chucks and end mill holders common in precision machining setups. It is well suited to finishing passes on close-tolerance features in aerospace, mold-and-die, and medical component work.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.015 inch corner radius reduces stress risers in milled pockets and profiles\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and extends tool life in ferrous and stainless materials\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide substrate supports higher feed rates and tighter tolerances than HSS\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes provide efficient chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge, ramp, and helical entry\u003c\/li\u003e\n\u003cli\u003e1\/8 inch shank diameter fits standard precision collet systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in standard CNC and manual milling machines accepting a 1\/8 inch shank end mill holder or collet chuck.

Secure the 1\/8 inch shank in a clean, properly sized collet or end mill holder and torque to the machine tool manufacturer specification before engaging the spindle. Inspect the collet bore and tool shank for chips or contamination prior to seating. Never run the tool above the speed and feed parameters established for the workpiece material and machine rigidity; exceeding these limits with small-diameter carbide tooling significantly increases the risk of breakage.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/16 inch (0.0625 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 0.001 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inch\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: 3\/16 inch (0.3125 inch)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\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 End\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 2.13 x 0.25 x 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27112803\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: 12176897\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51755255791922,"sku":"12176897","price":30.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/82aa49e508f93d93bcfeecf24c0d6ad6.jpg?v=1788952728","url":"https:\/\/voomisupply.com\/products\/accupro-12176897-corner-radius-end-mill-1-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
