Built from micrograin carbide and coated with AlTiN (aluminum titanium nitride), it handles elevated cutting temperatures and abrasive workpiece materials. The 3\/4 inch cutting diameter pairs with a 1 inch length of cut and a 37.5-degree helix angle for aggressive chip evacuation and smooth surface finishes. Centercutting geometry allows plunge entry. This tool is installed and operated by machinists on CNC machining centers and manual mills running compatible toolholders.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits high-speed finishing and semi-finishing passes in ferrous and non-ferrous materials including hardened steels, stainless alloys, and cast iron. The extended reach configuration, with a 3-1\/8 inch reach length and 6 inch overall length, allows access to deeper pockets and stepped features where shorter tooling cannot reach. The spiral flute geometry with right-hand cut and right-hand flute direction makes it a standard orientation for conventional CNC spindle setups. Single-end configuration means the tool is replaced rather than indexed when worn.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e7-flute solid micrograin carbide construction for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN coating for heat resistance in dry and semi-dry cutting conditions\u003c\/li\u003e\n  \u003cli\u003e37.5-degree spiral helix angle promotes efficient chip evacuation\u003c\/li\u003e\n  \u003cli\u003eCentercutting design permits direct plunge milling\u003c\/li\u003e\n  \u003cli\u003eExtended reach at 3-1\/8 inches for deep-pocket and tall-workpiece applications\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut and right-hand flute, compatible with standard CNC spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting 3\/4 inch straight shank toolholders including ER collet chucks, hydraulic chucks, and shrink-fit holders with a 3\/4 inch bore.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation and tool changes must be performed with the machine spindle fully stopped and the control in a safe state per shop lockout\/tagout procedures. Confirm the toolholder bore and collet size match the 3\/4 inch shank diameter before clamping. Do not exceed the toolholder manufacturer's recommended runout tolerance, as excessive runout accelerates carbide chipping on a 7-flute tool. A licensed machinist or qualified CNC operator should set tool length offsets and verify clearance before initiating the first cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide, Micrograin Grade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: AlTiN\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1 inch (range 1.0000 to 1.2500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eReach Length\u003c\/strong\u003e: 3-1\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 37.5 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\u003eExtended Reach\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter Tolerance\u003c\/strong\u003e: +0.000 \/ -0.002 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter Tolerance\u003c\/strong\u003e: -0.0001 \/ -0.0004 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1.384 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 6.13 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Length\u003c\/strong\u003e: 1 inch\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: 12178702\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748314054962,"sku":"12178702","price":485.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1c240b7df987a7716ad7e4ca66fe6849.jpg?v=1788892288","url":"https:\/\/voomisupply.com\/products\/accupro-12178702-square-end-mill-3-4-in-7-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
