It features a 3\/4 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length. The micrograin carbide construction provides rigidity and wear resistance under aggressive feed conditions. A 40-degree helix angle and spiral flute geometry promote efficient chip evacuation and reduced cutting forces. The nACRo coating adds thermal and oxidation resistance, extending tool life in high-speed and dry-cutting applications. This end mill is centercutting, allowing plunge entry directly into the workpiece. It is intended for use by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\u003cp\u003eThis end mill suits a wide range of milling operations including slotting, profiling, and pocketing on CNC machining centers and manual mills. The 3\/4 inch shank diameter provides secure gripping in standard end mill holders, collet chucks, and shrink-fit toolholders. With a 3 inch length of cut and no extended reach configuration, it is well suited for shallow-to-medium depth passes where tool rigidity is a priority. Right-hand cut and right-hand flute orientation make it compatible with standard spindle rotation on vertical and horizontal machining centers.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003enACRo coating for thermal resistance and reduced tool wear in high-speed applications\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle with spiral flutes for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without a pre-drilled hole\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute for use with standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003eMill diameter tolerance of +0.000 \/ -0.002 inches ensures consistent fitment\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-fit tool for standard 3\/4 inch end mill holders, collet chucks, and shrink-fit tooling systems on CNC machining centers and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the spindle is fully stopped and the machine is in an e-stop or powered-down state before changing tooling. Seat the shank to the recommended engagement depth in the toolholder and torque the retention mechanism per the toolholder manufacturer specification. Verify runout with a dial indicator before beginning a cut to avoid premature tool failure or dimensional error.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 4\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: 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\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\u003eCoating\/Finish\u003c\/strong\u003e: nACRo\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\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\u003eExtended Reach\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: 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: 12179052\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51730574115122,"sku":"12179052","price":494.85,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/956f5897da136d5317737e59273360e6_7a1d1134-30eb-40bc-b45a-24b76678e68f.jpg?v=1788719746","url":"https:\/\/voomisupply.com\/products\/accupro-12179052-square-end-mill-3-4-in-4-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
