Built from micrograin carbide, it delivers the rigidity and edge retention required for demanding cuts. The 2-flute configuration with a 40-degree spiral helix promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length with a 3-inch length of cut, this is an extra-long reach tool suited for deep-pocket and stepped-feature work. Centercutting geometry allows direct plunge entry without a pre-drilled hole. This tool is installed and operated by machinists and CNC programmers working on mills and machining centers.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in both manual and CNC milling operations where extended reach is required. The extra-long body makes it well suited for deep cavity work, side-wall finishing, and applications where standard-length tools cannot reach the workpiece feature. The right-hand cut and right-hand flute spiral are compatible with conventional and climb milling strategies. Uncoated micrograin carbide construction is appropriate for dry cutting or use with cutting fluid in ferrous and non-ferrous materials where a coating-specific chemistry is not required.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for edge retention and rigidity in demanding cuts\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and smooth surface finish\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pilot hole\u003c\/li\u003e\n\u003cli\u003eExtra-long 6-inch OAL with 3-inch LOC for deep-pocket and extended-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand spiral flute compatible with standard milling spindle rotation\u003c\/li\u003e\n\u003cli\u003e2-flute geometry balances chip clearance and tool strength for slotting and profiling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit tooling selection for milling machines and machining centers accepting a 9\/16-inch straight shank in a collet, end mill holder, or equivalent toolholding system.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the spindle is fully powered down and at rest before mounting or removing the tool. Seat the shank fully into the toolholder to the recommended engagement depth before tightening to prevent runout and pull-out during operation. Verify shank diameter tolerance stack-up against the toolholder bore specification before use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\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\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 9\/16 inch (0.5625 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\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\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\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength Type\u003c\/strong\u003e: Extra Long\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: 0.35 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: 12181764\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730060247346,"sku":"12181764","price":167.32,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d7ee1f0e6c16f2e7217ad820197831ff.jpg?v=1788711006","url":"https:\/\/voomisupply.com\/products\/accupro-12181764-square-end-mill-9-16-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
