With a 5\/8-inch cutting diameter and a 3-inch length of cut, it handles deep-pocket and slot milling where shorter tooling cannot reach. The 40-degree helix angle promotes efficient chip evacuation and smooth cutting action. At 6 inches overall length, this is an extra-long configuration suited for extended-reach applications. Micrograin carbide construction provides the hardness and wear resistance needed in production machining environments. CNC machinists and toolroom operators are the primary users.\u003c\/p\u003e\u003cp\u003eThis end mill is intended for use in vertical machining centers, CNC mills, and manual knee mills where an extended reach is required. Typical applications include deep cavity milling, shoulder milling, and full-slot cutting. The centercutting geometry allows plunge entry directly into the workpiece. The right-hand cut and right-hand spiral flute configuration is standard for conventional spindle rotation. The uncoated finish makes this tool a straightforward choice for shops that prefer to manage coatings separately or are working with non-ferrous materials.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5\/8-inch cutting diameter with mill diameter tolerance of +0.000 \/ -0.002 inches for consistent sizing\u003c\/li\u003e\n\u003cli\u003e3-inch length of cut for deep-pocket and extended-reach milling\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes aggressive chip evacuation and reduced heat buildup\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute spiral configuration for standard CNC spindle rotation\u003c\/li\u003e\n\u003cli\u003e6-inch overall length classified as extra long for clearance in deep setups\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use solid carbide square end mill for CNC and manual milling applications requiring a 5\/8-inch diameter, 5\/8-inch straight shank, and extra-long reach geometry.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by machinists and CNC tooling technicians. Ensure the machine spindle is fully stopped and locked out before changing tooling. Secure the 5\/8-inch shank in a properly sized collet or end mill holder, verifying runout with a dial indicator before production use. Follow shop-specific feeds and speeds protocols for the workpiece material; do not exceed the toolholder's rated clamping torque.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 inches)\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\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/8 inch (0.6250 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\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\u003eLength Type\u003c\/strong\u003e: Extra Long\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.6 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: 12182259\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51731788726578,"sku":"12182259","price":206.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/5cd93566906dcb48bb819e8c539f1b4a.jpg?v=1788734944","url":"https:\/\/voomisupply.com\/products\/accupro-12182259-square-end-mill-5-8-inch-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
