Built from micrograin carbide, it delivers the rigidity and edge retention needed for tight-tolerance profiling, contour milling, and draft-angle work. The 3-flute, right-hand spiral configuration with a 30-degree helix angle promotes efficient chip evacuation while maintaining surface finish quality. With a 3\/8-inch small end diameter, 1\/2-inch shank, and 1-1\/4-inch length of cut, this tool is suited for machinists running CNC mills or manual knee mills where controlled material removal depth is critical.\u003c\/p\u003e\u003cp\u003eThis tapered end mill is used in job shop, production machining, and toolroom environments. The square end profile and center-cutting capability allow it to be plunged directly into a workpiece or used for ramp entry. Typical applications include mold and die work, aerospace component profiling, and any operation where a precise draft angle must be maintained along the full length of cut. The uncoated finish makes it compatible with a wide range of materials and easy to resharpen.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-degree taper per side for accurate draft-angle milling\u003c\/li\u003e\n\u003cli\u003eSolid micrograin carbide construction for superior wear resistance and edge retention\u003c\/li\u003e\n\u003cli\u003e3-flute right-hand spiral with 30-degree helix for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry or ramp milling\u003c\/li\u003e\n\u003cli\u003eUncoated finish supports resharpening and broad material compatibility\u003c\/li\u003e\n\u003cli\u003eSquare end profile suited for contour, profiling, and cavity work\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or direct-use tapered end mill for CNC machining centers and manual mills accepting a 1\/2-inch straight shank toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following standard toolholding procedures. Secure the 1\/2-inch shank in a collet, end mill holder, or shrink-fit chuck to the manufacturer-recommended clamping length before use. Verify runout with a dial indicator before beginning a cut, as excessive runout accelerates tool wear and degrades surface finish. Always confirm spindle speed and feed rate are appropriate for the workpiece material before engaging the cut.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide (Micrograin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 1-1\/4 inches (1.2500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 3-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 2 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\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: 12177491\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51744272384306,"sku":"12177491","price":134.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/935b622c45187c3c6644488193d3b92e.jpg?v=1788855466","url":"https:\/\/voomisupply.com\/products\/accupro-12177491-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
