Built from solid micrograin carbide and coated with AlCrTiN for heat and wear resistance, this tool handles demanding cutting conditions where tool life is critical. It features a 1\/8 inch diameter, a 1\/2 inch length of cut, a 0.010 inch corner radius, and a 38-degree helix angle. With 5 flutes and a variable index geometry, it is suited for machinists and tool-and-die professionals who need consistent finish quality and edge stability at higher feed rates.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in CNC machining centers and manual mills where small-diameter profiling, slotting, or finishing passes are required. The center-cutting design allows plunge entry, making it practical for pocketing operations. The right-hand flute direction and right-hand cutting orientation are standard for conventional CNC setups. Its 2 inch overall length and 1\/8 inch shank diameter make it a direct fit for standard collets and end mill holders sized for small-diameter tooling.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and wear resistance in hard materials\u003c\/li\u003e\n\u003cli\u003eAlCrTiN coating provides thermal protection and extends tool life in dry or high-speed cutting\u003c\/li\u003e\n\u003cli\u003e5-flute design increases chip load per tooth and improves surface finish\u003c\/li\u003e\n\u003cli\u003eVariable index geometry reduces harmonic vibration during cutting\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capability allows direct plunge entry for pocketing\u003c\/li\u003e\n\u003cli\u003e0.010 inch corner radius reduces stress concentration at the cutting edge\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with standard 1\/8 inch collets and end mill holders on CNC machining centers and manual milling machines.

Ensure the spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended gauge line depth and torque the collet nut according to the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning a cut, as excessive runout on small-diameter carbide tools increases breakage risk.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1\/8 inch (0.1250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1\/2 inch (0.5000 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: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.010 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 38 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Corner Radius\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\u003eCenter Cutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVariable Index\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\u003c\/strong\u003e: AlCrTiN\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle or Double End\u003c\/strong\u003e: Single\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: HS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: 311360\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732743881010,"sku":"311360","price":37.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a8254d0ae7b10182ca163db3aac307e6_d26dd74d-584d-410d-9fed-33e35f241738.jpg?v=1788746231","url":"https:\/\/voomisupply.com\/products\/accupro-311360-corner-radius-end-mill-1-8-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
