It features a 5\/8 inch cutting diameter, a 3 inch length of cut, and a 6 inch overall length, placing it in the extra-long category for extended-reach work. The two-flute, right-hand spiral configuration runs at a 40-degree helix angle, promoting efficient chip evacuation and smooth cutting action. Micrograin carbide construction delivers hardness and wear resistance suited to demanding cuts in ferrous and non-ferrous materials. The centercutting geometry allows plunge entry directly into the workpiece.\u003c\/p\u003e\u003cp\u003eThis end mill is suited for milling slots, pockets, and profiles where reach beyond standard length tooling is required. The uncoated finish makes it a straightforward choice for shops that regrind tooling or work with materials where coated tools offer no advantage. It is appropriate for use in CNC machining centers and manual knee mills with proper toolholding. The 5\/8 inch shank diameter matches the cutting diameter, supporting use in standard collet chucks and end mill holders of that bore size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e40-degree helix angle promotes efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting geometry allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eExtra-long 6 inch overall length with 3 inch length of cut for extended-reach applications\u003c\/li\u003e\n\u003cli\u003eRight-hand cut and right-hand flute spiral configuration\u003c\/li\u003e\n\u003cli\u003eUncoated — compatible with regrind programs or uncoated-preferred applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for 5\/8 inch shank square end mills in standard collet chucks, end mill holders, and hydraulic chucks accepting 5\/8 inch bore toolholding.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop toolholding procedures. Ensure the machine spindle is fully stopped and the tool changer or spindle lock is engaged before mounting or removing the end mill. Verify runout with a dial indicator after seating in the holder, as excessive runout reduces tool life and surface finish quality. Follow the toolholder manufacturer minimum insertion depth guidelines to maintain secure clamping.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\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\u003eOverall Length\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.6250 inches (5\/8 inch)\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\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\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: 12181767\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51748759896370,"sku":"12181767","price":212.24,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e90bc6ad999d6ad8a857ba813d0abc77.jpg?v=1788897937","url":"https:\/\/voomisupply.com\/products\/accupro-12181767-square-end-mill-5-8-inch-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
