It features a 3\/4-inch cutting diameter, a 1-5\/8-inch length of cut, and a 4-inch overall length with a matching 3\/4-inch shank diameter. The micrograin carbide construction delivers hardness and wear resistance suited for demanding machining environments. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. This end mill is centercutting, allowing direct plunge entry into the workpiece, and is manufactured to tight diameter tolerances for consistent, repeatable results. Machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\u003cp\u003eThis end mill is well suited for slot milling, profiling, and contouring in both manual and CNC machining centers. Its regular length designation and 3-flute geometry make it a practical choice for general-purpose finishing and semi-finishing passes. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC vertical machining center setups. No chipbreaker geometry means clean, uninterrupted cutting edges for smoother surface finishes on ferrous and non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for high hardness and extended tool life\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting forces\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge milling without a pre-drilled entry hole\u003c\/li\u003e\n\u003cli\u003e3-flute geometry balances chip clearance with surface finish quality\u003c\/li\u003e\n\u003cli\u003eUncoated for straightforward regrinding and compatibility with a wide range of coolants\u003c\/li\u003e\n\u003cli\u003eTight mill diameter tolerance of +0.000 \/ -0.002 inches for dimensional accuracy\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a standard-shank replacement end mill for CNC machining centers and manual mills accepting a 3\/4-inch tool holder or collet.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety protocols. Ensure the spindle is fully stopped and the machine is powered down before changing tooling. Use a properly sized collet, end mill holder, or shrink-fit chuck rated for the 3\/4-inch shank diameter to ensure runout is within acceptable limits. Verify tool projection and stick-out are appropriate for the intended cut depth before beginning any machining operation.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-5\/8 inches (1.6250 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/4 inches (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\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\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: Regular\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 pound\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: 12178617\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738104824114,"sku":"12178617","price":216.31,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d28e258f6ca1899f7a8177c078e46021.jpg?v=1788796219","url":"https:\/\/voomisupply.com\/products\/accupro-12178617-square-end-mill-3-4-in-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
