Built from micrograin carbide, it delivers consistent edge integrity at higher feeds and speeds than high-speed steel tooling. The 3-flute geometry with a 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces on the workpiece. At 27\/64 inch (0.4219 inches) in diameter with a 1 inch length of cut and a 7\/16 inch shank diameter, this tool fits standard ER and end mill holders commonly used in CNC machining centers and manual mills. It is uncoated and ready for use with appropriate cutting fluids.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for slotting, profiling, and peripheral milling in general-purpose machining environments. The centercutting design allows plunge entry directly into the workpiece, expanding its use to ramping and helical interpolation operations. The right-hand cut, right-hand spiral flute configuration is the standard setup for the majority of CNC and manual milling applications. It fits production shops, tool rooms, and maintenance machining operations where a regular-length, non-chipbreaker end mill is specified.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for consistent edge wear resistance\u003c\/li\u003e\n\u003cli\u003e3-flute, 40-degree helix spiral geometry for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design supports plunge entry, ramping, and helical milling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute configuration for standard milling setups\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for use with cutting fluids across a range of workpiece materials\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of plus 0.000 \/ minus 0.002 inches for close-tolerance work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank solid carbide square end mill compatible with ER collet chucks, end mill holders, and milling chucks accepting a 7\/16 inch shank diameter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Secure the shank fully within the collet or holder to the recommended grip length before tightening, and verify runout with a dial indicator before cutting. Confirm spindle direction and feed rate programming match the right-hand cut specification before initiating a tool path. Always bring the spindle to a full stop before changing or inspecting the tool.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 27\/64 inch (0.4219 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 7\/16 inch (0.4375 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 inches\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: 40 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\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: Uncoated\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\u003eMill Diameter Tolerance\u003c\/strong\u003e: plus 0.000 \/ minus 0.002 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: minus 0.0001 \/ minus 0.0004 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Regular\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 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: 12182046\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730959794482,"sku":"12182046","price":67.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/81cf6a3b58c93c4ebb9f44cc3307d181.jpg?v=1788725324","url":"https:\/\/voomisupply.com\/products\/accupro-12182046-square-end-mill-27-64-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
