It features a 1\/4 inch small end diameter, a 2-1\/4 inch length of cut, and a 2-degree taper angle per side. Three spiral flutes with a 30-degree helix angle promote efficient chip evacuation and smooth cutting action. The micrograin carbide construction delivers hardness and wear resistance suited to demanding ferrous and non-ferrous machining applications. The uncoated finish makes this tool a reliable baseline option for shops that apply their own coatings or work in materials where coating adhesion is a factor.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for producing tapered slots, draft angles, and cavity work in mold and die applications as well as general production machining. The square end geometry supports flat-bottom cuts. Right-hand flute direction and center-cutting capability allow both plunge and peripheral cutting. The 7\/16 inch shank diameter and 4 inch overall length suit standard ER and end mill holders commonly found in vertical machining center setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-degree taper angle per side for precise draft and taper profile control\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for hardness and edge retention\u003c\/li\u003e\n\u003cli\u003e3 spiral flutes with 30-degree helix angle for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCenter-cutting design allows direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand cut, right-hand flute configuration compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for re-coating or use in applications where coatings are not required\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement or standard tooling option for CNC machining centers and manual mills accepting a 7\/16 inch shank diameter in standard end mill or collet-style toolholders.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or tooling technician. Secure the 7\/16 inch shank in a properly sized collet or end mill holder, ensuring adequate engagement length and runout within machine tolerances. Inspect the cutting edges for chips or damage before mounting. Power down and lock out the spindle before changing tooling per standard shop safety practice.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: 7\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 4 inches\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\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 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\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\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: 12177489\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739303641394,"sku":"12177489","price":221.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/75fba3c9ac77423409781d30042cf98f.jpg?v=1788812894","url":"https:\/\/voomisupply.com\/products\/accupro-12177489-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
