With a 1\/8 inch cutting diameter and a 0.01 inch corner radius, this tool produces consistent, lightly radiused edges that reduce stress concentrations in finished workpieces. The AlTiN coating provides high heat resistance and extended tool life in ferrous and hard materials. It features a single-end, centercutting design with a right-hand spiral flute pattern and 40-degree helix angle, making it suitable for plunge, slot, and profile milling. Machinists and tool-and-die professionals use this end mill in CNC machining centers and manual mills.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for use in light-duty to medium-duty milling applications on steel, stainless steel, cast iron, and similar ferrous alloys. The micrograin carbide substrate supports high-speed cutting with tight dimensional tolerances. The 1\/2 inch length of cut accommodates shallow-to-moderate depth passes, while the 1\/8 inch shank diameter fits standard collet chucks on CNC machining centers and manual knee mills. It is a single-quantity tool commonly stocked by job shops, mold makers, and precision machine shops.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.01 inch corner radius reduces edge chipping and stress risers in finish passes\u003c\/li\u003e\n\u003cli\u003eAlTiN coating improves heat resistance and extends tool life in ferrous materials\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide substrate supports tight tolerances and rigidity\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction and cutting direction for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard tooling selection for 1\/8 inch collet chucks and tool holders used on CNC machining centers and conventional milling machines requiring a 1\/8 inch shank end mill.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. The tool must be seated fully and evenly in a properly sized collet or end mill holder before tightening to prevent runout. Verify spindle speed and feed rate parameters against the tool manufacturer's recommendations for the specific workpiece material before cutting. Inspect the collet and holder for wear or contamination prior to installation to maintain shank diameter tolerance specifications.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorner Radius\u003c\/strong\u003e: 0.01 inches\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\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 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\u003eCentercutting\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: AlTiN\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\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: 12181267\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51749684511026,"sku":"12181267","price":35.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9bc18d1865155ceac59a0c9f62ba8ad3.jpg?v=1788909184","url":"https:\/\/voomisupply.com\/products\/accupro-12181267-corner-radius-end-mill-1-8-in-2-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
