Built from micrograin solid carbide, this single-end, center-cutting tool features four right-hand spiral flutes with a 30-degree helix angle. The cutting diameter measures 0.0313 inches with a corner radius of 0.015 inches, making it well suited for producing smooth, radiused transitions at the base of pockets and shoulders. The bright, uncoated finish is appropriate for non-ferrous metals and other materials where coating interaction is a concern. Machinists and toolroom operators rely on this geometry for fine detail work at small diameters.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC milling and toolroom machining applications where small-diameter, close-tolerance profiling or pocketing is required. The center-cutting design allows direct plunge entry, adding flexibility to contouring and ramping operations. Its compact shank and short length of cut make it particularly effective in high-speed finishing passes on aluminum, brass, plastics, and similar workpiece materials. It is sold individually and is appropriate for production or prototype work demanding consistent radius control.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance at small diameters\u003c\/li\u003e\n\u003cli\u003e0.015-inch corner radius reduces stress concentration and improves surface finish at pocket floors\u003c\/li\u003e\n\u003cli\u003eFour right-hand spiral flutes with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting end geometry permits direct plunge milling\u003c\/li\u003e\n\u003cli\u003eBright, uncoated finish suitable for non-ferrous and abrasive workpiece materials\u003c\/li\u003e\n\u003cli\u003eTight diameter tolerance of +0.0002 \/ -0.0008 inches ensures dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard shank end mill compatible with 1\/8-inch collets and matching tool holders used in CNC machining centers, manual mills, and high-speed spindles configured for small-diameter carbide tooling.\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 shop lockout\/tagout procedures. Seat the 1\/8-inch shank fully into a clean, properly sized collet or end mill holder and torque the retention nut to the holder manufacturer's specification. Inspect the cutting edges under magnification before use; carbide at this diameter is brittle and sensitive to handling damage. Confirm runout at the tool tip with a dial indicator before committing to a finish pass.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.0313 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0002 \/ -0.0008 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.015 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: 0.001 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: 0.09375 inches (3\/32 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.125 inches (1\/8 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Bright\/Uncoated\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: 12176876\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739189182770,"sku":"12176876","price":28.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ecd20ac058efb8db0117f83e922cff12.jpg?v=1788811063","url":"https:\/\/voomisupply.com\/products\/accupro-12176876-corner-radius-end-mill-0-0313in-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
