Built from powdered metal, it offers improved toughness and wear resistance compared to standard high-speed steel. The tool features a 1 inch cutting diameter, a 2 inch length of cut, and a 42-degree helix angle that promotes efficient chip evacuation and reduces cutting forces. Three spiral flutes deliver a balance of rigidity and chip clearance suited to a wide range of materials. Machinists, tool-and-die professionals, and CNC operators working in metalworking shops are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for use in vertical machining centers, CNC mills, and manual knee mills performing slotting, profiling, and peripheral milling operations. The 1 inch shank diameter provides a stable, secure fit in standard collet chucks and end mill holders. With a 4.5 inch overall length and a right-hand cut with right-hand flute orientation, it is set up for conventional and climb milling approaches on ferrous and non-ferrous materials. The uncoated surface finish makes it appropriate for applications where coating compatibility is a concern or where regrinding is planned.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePowdered metal construction for improved toughness and edge retention over standard HSS\u003c\/li\u003e\n  \u003cli\u003e42-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry into the workpiece\u003c\/li\u003e\n  \u003cli\u003eThree spiral flutes balance chip clearance with tool body strength\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute orientation for standard spindle operation\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for regrinding and coating applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end square end mill with a 1 inch shank diameter, compatible with end mill holders and collet chucks sized for 1 inch straight-shank tooling used in CNC and manual milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified machinists or CNC setup technicians. Ensure the machine spindle is fully stopped and the tool changer or quill is locked before inserting or removing the end mill. Verify that the holder bore and collet are clean and free of chips before seating the shank to the recommended insertion depth. Follow the machine tool manufacturer torque specifications for drawbar and collet nut tightening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1 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: 42 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCutting Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\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: Powdered Metal\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.0015 \/ -0.0000 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0005 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\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: E999921230\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51747421815090,"sku":"E999921230","price":290.81,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cb712e72b5acb6104ceca41ad97f3b7f.jpg?v=1788879864","url":"https:\/\/voomisupply.com\/products\/accupro-e999921230-square-end-mill-1-in-3-flute-powdered-metal","provider":"Voomi Supply","version":"1.0","type":"link"}
