With a 0.6299-inch (16.00 mm) cutting diameter and a 1.2598-inch (32.00 mm) length of cut, this tool handles moderate-depth slotting, profiling, and peripheral milling in a single-end configuration. The 40-degree helix angle promotes efficient chip evacuation and reduces cutting forces across a range of workpiece materials. Micrograin carbide construction provides the hardness and wear resistance needed for consistent performance in ferrous and non-ferrous applications. This tool is installed and run by machinists and CNC operators in job shop and production environments.\u003c\/p\u003e\n\u003cp\u003eThis end mill is suited for CNC machining centers and manual milling machines where a right-hand cut, right-hand spiral flute tool is required. The centercutting geometry allows plunge entry into the workpiece, expanding its use to ramp milling and pocket entry without a pre-drilled start hole. The regular-length body keeps the tool rigid during full-depth passes. It is appropriate for use in general-purpose milling of steel, aluminum, cast iron, and similar materials where an uncoated micrograin carbide tool is the specified choice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSolid micrograin carbide construction for hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003e40-degree helix angle for efficient chip evacuation and reduced cutting force\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry and ramp milling\u003c\/li\u003e\n  \u003cli\u003e2-flute geometry provides chip clearance in slotting and pocket milling\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suitable for use with cutting fluids on a broad range of materials\u003c\/li\u003e\n  \u003cli\u003eRight-hand cut, right-hand spiral flute configuration for standard spindle rotation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard single-end square end mill with a 0.6299-inch (16.00 mm) shank diameter, compatible with milling machine collets, end mill holders, and toolholders accepting that shank size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator with the spindle fully stopped and machine power isolated before tooling changes. Seat the shank fully into the holder to the recommended engagement depth and torque the retention mechanism per the toolholder manufacturer specifications. Verify runout with a dial indicator before beginning the cut. Never exceed the tool manufacturer recommended speeds and feeds for the workpiece material and depth of cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.6299 inches (16.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1.2598 inches (32.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3.504 inches (89.00 mm)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 16.00 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 2\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 40 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial Grade\u003c\/strong\u003e: Micrograin\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\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\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: 12181521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742376558898,"sku":"12181521","price":196.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/7cfbf8aeea89682f2703d22c88ddb1ac.jpg?v=1788837069","url":"https:\/\/voomisupply.com\/products\/accupro-12181521-square-end-mill-0-6299-in-2-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
