Built from micrograin solid carbide and coated with AlTiN (aluminum titanium nitride), this tool handles high-heat applications and abrasive workpiece materials with consistent edge integrity. It features a 3\/16 inch mill diameter, a 9\/16 inch length of cut, and a 0.01 inch corner radius that reduces stress concentration at corners and extends part life. The single-end, centercutting design allows plunge entry as well as lateral milling passes. Machinists and CNC operators in job shops and production environments use this end mill for finish and semi-finish profiling, slotting, and contouring operations.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for milling ferrous and non-ferrous metals, hardened steels, stainless, and high-temperature alloys where corner breakout control is critical. The 35-degree helix angle promotes smooth chip evacuation and reduces cutting forces during lateral passes. The 3\/16 inch shank diameter matches the mill diameter for direct collet or end mill holder mounting in standard tooling setups. It is a regular-length tool, making it appropriate for general-purpose cnc machining centers and manual mills where rigidity and runout control are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMicrograin solid carbide substrate for hardness and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating extends tool life in high-temperature and abrasive cutting conditions\u003c\/li\u003e\n  \u003cli\u003e0.01 inch corner radius reduces edge chipping and stress risers at part corners\u003c\/li\u003e\n  \u003cli\u003e3-flute geometry balances chip clearance and cutting edge strength\u003c\/li\u003e\n  \u003cli\u003e35-degree helix angle promotes efficient chip evacuation and lower cutting forces\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows plunge milling without a pilot hole\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-mount replacement or standard tooling selection for CNC machining centers and manual mills accepting a 3\/16 inch shank diameter collet or end mill holder.

Ensure the spindle is fully stopped and the machine is in an e-stop or locked-out state before loading or changing tooling. Seat the shank fully in the collet or holder and torque the retention system to the toolholder manufacturer specification. Verify runout at the tip before initiating a cut, as excessive runout accelerates edge wear on small-diameter carbide tools.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/16 inch (0.1875 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 35 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\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\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCorner Radius Tolerance\u003c\/strong\u003e: plus or minus 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\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\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: 12179664\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749556617522,"sku":"12179664","price":41.68,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/711d699626ec33a47736509d38d625ca.jpg?v=1788907576","url":"https:\/\/voomisupply.com\/products\/accupro-12179664-corner-radius-end-mill-3-16-in-3-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
