It features a 1\/4 inch small end diameter, a 1-degree taper angle per side, and a 1-1\/4 inch length of cut. The three-flute, right-hand spiral geometry combined with a 30-degree helix angle promotes efficient chip evacuation and smooth cutting action. Manufactured from micrograin solid carbide, this tool delivers the rigidity and wear resistance needed for demanding materials. The uncoated finish makes it well suited for applications where coating buildup could affect dimensional accuracy. CNC machinists and tool-and-die professionals are the primary users of this tool.\u003c\/p\u003e\n\u003cp\u003eThis tapered end mill is used in mold making, die work, and general CNC machining where tapered walls or draft angles must be cut into a workpiece. The 5\/16 inch shank diameter fits standard end mill holders and collet chucks. With a 3 inch overall length and 1-1\/4 inch length of cut, it reaches into moderate-depth cavities while maintaining tool stability. It is centercutting, allowing direct plunge entry into the workpiece without pre-drilling. Applications include tapered slot milling, core and cavity work, and angled wall finishing in ferrous and non-ferrous materials.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e1-degree taper angle per side for controlled draft-angle milling\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for improved hardness and edge retention\u003c\/li\u003e\n  \u003cli\u003eThree right-hand spiral flutes with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n  \u003cli\u003eCentercutting design allows direct plunge entry without pre-drilling\u003c\/li\u003e\n  \u003cli\u003eUncoated finish preserves dimensional accuracy in tight-tolerance applications\u003c\/li\u003e\n  \u003cli\u003e5\/16 inch shank compatible with standard collet chucks and end mill holders\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for standard 5\/16 inch shank end mill holders and collet systems used in CNC machining centers and manual mills requiring a 1-degree-per-side tapered end mill profile.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified CNC machinist or toolroom professional. Ensure the machine spindle is fully stopped and locked out before changing tooling. Seat the shank fully into the collet or holder to the recommended engagement depth before torquing the retention hardware. Verify runout with a dial indicator after mounting to confirm concentricity before beginning a cut.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 5\/16 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 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 1 degree\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHelix Angle\u003c\/strong\u003e: 30 degrees\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Square\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\u003eCoating\/Finish\u003c\/strong\u003e: Uncoated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\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: 12177461\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51743893553458,"sku":"12177461","price":134.84,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/471ce9ff2fce4de5abc00383bba8e708.jpg?v=1788850978","url":"https:\/\/voomisupply.com\/products\/accupro-12177461-tapered-end-mill-1-4-in-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
