It features a 9\/16-inch cutting diameter, a 1-1\/2-inch length of cut, and a 3-1\/2-inch overall length with a matching 9\/16-inch shank diameter. The 5-flute geometry paired with a 45-degree helix angle promotes efficient chip evacuation and improved surface finish at higher feed rates. An AlTiN coating provides elevated heat resistance and extended tool life in dry or semi-dry cutting conditions. This end mill is centercutting, allowing direct plunge entry into the workpiece. It is intended for use by machinists and CNC operators in precision machining environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for peripheral milling, slotting, and plunge operations in a range of materials where a carbide substrate and AlTiN finish deliver a clear advantage over HSS tooling. The right-hand cut and right-hand spiral flute configuration is standard for conventional CNC machining centers and manual mills. The regular-length profile makes it a practical choice for general-purpose milling where extended reach is not required. Micrograin carbide construction supports tighter tolerances and longer run intervals between tool changes.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide substrate for rigidity and wear resistance\u003c\/li\u003e\n  \u003cli\u003eAlTiN finish for high-heat performance in ferrous cutting applications\u003c\/li\u003e\n  \u003cli\u003e5-flute design increases feed rate capability and improves surface finish\u003c\/li\u003e\n  \u003cli\u003e45-degree helix angle promotes smooth cutting action and efficient chip flow\u003c\/li\u003e\n  \u003cli\u003eCentercutting geometry allows direct plunge milling without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand flute spiral configuration for standard CNC setups\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or direct-fit cutting tool for CNC machining centers and manual mills accepting a 9\/16-inch straight shank end mill.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist familiar with CNC tooling and collet or end mill holder systems. Ensure the machine spindle is fully stopped and locked out before inserting or removing the end mill. Verify collet size matches the 9\/16-inch shank diameter and that the tool is seated to the appropriate gauge length before tightening. Inspect runout after seating to confirm the tool is properly secured before initiating a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 5\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: 1.5 inches (1-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.5625 inches (9\/16 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.5 inches (3-1\/2 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 45 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\u003eFinish\u003c\/strong\u003e: AlTiN\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\u003eExtended Reach\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Helix\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVariable Index\u003c\/strong\u003e: No\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eChipbreaker\u003c\/strong\u003e: No\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: 12183800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51738559643954,"sku":"12183800","price":168.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/f77a04203a00028ea8518d57d59ca763.jpg?v=1788801012","url":"https:\/\/voomisupply.com\/products\/accupro-12183800-square-end-mill-9-16-in-5-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
