Built from micrograin carbide, this tool delivers a 5-degree taper per side with a 1\/4 inch small end diameter and a 3\/4 inch length of cut. The square end geometry and right-hand spiral fluting make it well suited for profiling tapered pockets, mold cavities, and drafted walls in ferrous and non-ferrous materials. Three flutes provide a balance of chip clearance and cutting edge support. The 30-degree helix angle promotes smooth cutting action and efficient chip evacuation during deep-reach operations.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for applications that require precise tapered profiles. Typical use cases include die and mold work, aerospace component machining, and precision part manufacturing where draft angles must be held to tight tolerances. The 3\/8 inch shank diameter fits standard ER and milling chuck toolholders common in most CNC setups. With a 2-1\/2 inch overall length, the tool provides adequate reach for moderate-depth cavity work without excessive overhang.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5 degrees taper per side for accurate draft angle milling\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and wear resistance\u003c\/li\u003e\n\u003cli\u003e3 right-hand spiral flutes with 30-degree helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eSquare end profile suited for flat-bottomed tapered pockets\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing plunge entry where required\u003c\/li\u003e\n\u003cli\u003eUncoated finish compatible with coolant or dry cutting strategies\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 3\/8 inch shank diameter toolholder.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist following shop safety procedures. Secure the 3\/8 inch shank in a properly sized collet or end mill holder, ensuring adequate shank engagement and runout within acceptable limits before operation. Confirm spindle speed and feed rate settings are appropriate for the workpiece material before engaging the cut. Inspect the cutting edges for chips or damage before each use.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 3\/4 inch (0.7500 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 5 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 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\u003eMaterial\u003c\/strong\u003e: Solid Carbide (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\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: 12177530\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51740772401458,"sku":"12177530","price":96.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4879865c4d0a45b848d7e1f0f69bb3e2.jpg?v=1788827349","url":"https:\/\/voomisupply.com\/products\/accupro-12177530-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
