It features a 0.5-degree taper per side, a small end diameter of 0.25 inches, and a 2.25-inch length of cut, making it well suited for tapered slot milling, die work, and contour profiling. The micrograin carbide substrate provides rigidity and wear resistance in ferrous and non-ferrous materials. Three right-hand spiral flutes deliver efficient chip evacuation while maintaining a smooth cutting action. The uncoated finish suits applications where coating interaction with workpiece material is a concern or where frequent resharpening is expected.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual milling setups across tool-and-die, mold making, aerospace component, and precision parts manufacturing environments. The centercutting geometry allows plunge entry, expanding its utility in pocketing and slotting operations. The 5\/16-inch shank diameter fits standard collet chucks and end mill holders common in production and job shop settings. Its 4-inch overall length provides reach into deeper cavities without requiring extended-reach toolholders in most standard applications.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.5-degree taper per side for precise angular wall geometry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows direct plunge entry into workpiece material\u003c\/li\u003e\n\u003cli\u003eThree right-hand spiral flutes for efficient chip clearance and smooth finish\u003c\/li\u003e\n\u003cli\u003eUncoated surface for easy visual wear inspection and straightforward regrinding\u003c\/li\u003e\n\u003cli\u003e5\/16-inch shank compatible with standard collet and end mill holder systems\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 compatible with standard 5\/16-inch collet chucks and end mill holders on CNC and manual milling machines.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified machinist or CNC setup technician. Ensure the machine spindle is fully stopped and locked out before loading or changing tooling. Seat the shank fully into the collet or holder and torque retention hardware to the toolholder manufacturer specification. Verify runout with a dial indicator before beginning production cuts to prevent premature tool wear or workpiece scrap.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.3125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 2.25 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: 0.5 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\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\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: 12177444\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51739379794226,"sku":"12177444","price":101.42,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/37ef26176216fd9960372a551f259176.jpg?v=1788813817","url":"https:\/\/voomisupply.com\/products\/accupro-12177444-tapered-end-mill-3-flute-solid-carbide-uncoated","provider":"Voomi Supply","version":"1.0","type":"link"}
