It features a 1\/4 inch cutter head diameter, three flutes, and a right-hand cutting direction. The AlTiN coating improves heat resistance and extends tool life in demanding cutting environments. With an overall length of 2.5 inches and a 1\/4 inch shank diameter, this tool fits standard end mill holders and collet chucks used in CNC machining centers and manual milling machines. Machinists and toolroom operators working with steel, stainless, and hardened materials will find this tool well suited to high-speed finishing passes.\u003c\/p\u003e\n\u003cp\u003eThis chamfer mill is used in machine shops, production facilities, and toolrooms where consistent chamfer geometry and clean edge preparation are required. The single-end design and 0.0950 inch length of cut make it appropriate for light chamfering and spot-facing applications on close-tolerance parts. It is a practical choice for CNC operators running tight-tolerance programs where repeatable chamfer angles are critical. Coolant-through capability is not included, so external flood or mist coolant should be used when cutting heat-sensitive materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid carbide construction for rigidity and wear resistance in hardened materials\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating enhances thermal stability and reduces tool wear at elevated cutting speeds\u003c\/li\u003e\n  \u003cli\u003eThree-flute geometry balances chip evacuation and surface finish on chamfer passes\u003c\/li\u003e\n  \u003cli\u003eRight-hand cutting direction for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003e0.0950 inch length of cut suited to light chamfering and edge-breaking tasks\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch shank fits common collet chucks and end mill holders without adapters\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard 1\/4 inch shank chamfer mill compatible with CNC machining centers, vertical mills, and manual milling machines equipped with ER collet chucks or end mill holders accepting a 1\/4 inch shank diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC toolroom personnel. Ensure the machine spindle is fully stopped and locked out before loading or unloading the tool. Seat the shank fully into the collet or holder and torque the retention nut to the tool holder specification before running. Verify runout with a dial indicator before commencing production cuts to protect both the tool and the workpiece.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutter Head Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.0950 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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: Single\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 23241600\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: EM99943869\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739980202290,"sku":"EM99943869","price":57.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a28c340b5d2d3cb67b1f23a39893fe61.jpg?v=1788821015","url":"https:\/\/voomisupply.com\/products\/accupro-em99943869-chamfer-mill-1-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
