Built from micrograin solid carbide and coated with titanium carbonitride (TiCN), it delivers extended tool life and resistance to abrasion at elevated cutting speeds. The cutter features a 0.005 inch corner radius that produces a controlled, consistent edge break on finished surfaces while reducing stress concentration at part corners. With a 1\/16 inch cutting diameter, four right-hand spiral flutes, and a centercutting geometry, this end mill is suited for slotting, profiling, and plunging in tight-tolerance work where tool geometry and runout tolerance are critical.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for die and mold work, medical component machining, aerospace detail parts, and other applications requiring small-diameter, tight-tolerance cuts. The 3\/16 inch length of cut and 1\/8 inch shank diameter make it compatible with standard collet chucks and end mill holders used in light-to-medium milling setups. It is typically specified by machinists and tool-and-die technicians working to fine surface finish and dimensional tolerances.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance in demanding cuts\u003c\/li\u003e\n\u003cli\u003eTiCN coating improves surface hardness and reduces friction at the cutting edge\u003c\/li\u003e\n\u003cli\u003e0.005 inch corner radius reduces edge chipping and stress concentration on finished parts\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with centercutting capability allow plunge entry\u003c\/li\u003e\n\u003cli\u003eSingle-end design with right-hand cutting direction for standard CNC spindle compatibility\u003c\/li\u003e\n\u003cli\u003eCorner radius tolerance of plus or minus 0.001 inch supports consistent part geometry\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use cutting tool for CNC machining centers and manual mills accepting a 1\/8 inch shank diameter via standard collet or end mill holder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and locked out per facility lockout\/tagout procedures. Seat the 1\/8 inch shank fully into the collet or tool holder and torque the retention mechanism to the tool holder specification before cutting. Inspect runout with a dial indicator after seating; small-diameter carbide end mills are sensitive to runout and can fracture under eccentric loading. A licensed machinist or qualified CNC operator should verify feed rate, spindle speed, and depth of cut parameters before engaging the cut.\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\u003eShank Diameter\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/16 inch (0.6250 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\u003eCorner Radius\u003c\/strong\u003e: 0.005 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\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\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\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: 0.01 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: 12176895\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738899349810,"sku":"12176895","price":31.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/2d5702321fcb73c1d329c3cbaaf21c1a_598b6a92-04e4-4207-ac35-31b6cb76fa31.jpg?v=1788806436","url":"https:\/\/voomisupply.com\/products\/accupro-12176895-corner-radius-end-mill-1-16-in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
