Built from micrograin solid carbide, this tool delivers the rigidity and wear resistance needed for demanding cuts in steel, cast iron, aluminum, and similar materials. The square end geometry and 3-flute spiral configuration support clean side milling and finishing passes in tapered slots, draft pockets, and contoured workpiece features. With a 5-degree taper per side, a small end diameter of 3\/32 inches, and a 1-1\/4 inch length of cut, this end mill is sized for detailed work in tight geometries. Installation is performed by qualified machinists and CNC operators.\u003c\/p\u003e\n\u003cp\u003eThis end mill suits CNC machining centers and manual milling operations where tapered wall geometry is required. Typical applications include mold and die work, tooling fabrication, and precision part production in job shop and production environments. The 5\/16 inch shank diameter fits standard collet and end mill holders. The uncoated micrograin carbide construction makes it suitable for dry or flood-coolant cutting conditions across a wide range of workpiece materials. Right-hand flute direction matches standard spindle rotation on conventional and CNC knee mills and machining centers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e5-degree taper per side for accurate draft angle milling in slots and pockets\u003c\/li\u003e\n  \u003cli\u003eMicrograin solid carbide construction for superior edge retention and rigidity\u003c\/li\u003e\n  \u003cli\u003e3-flute spiral design with right-hand flute direction balances chip evacuation and finish quality\u003c\/li\u003e\n  \u003cli\u003eSquare end geometry supports flat-bottom tapered slot and wall finishing\u003c\/li\u003e\n  \u003cli\u003eCenter-cutting capability allows plunge entry into workpiece material\u003c\/li\u003e\n  \u003cli\u003eUncoated finish suits a broad range of materials and regrinding compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style solid carbide tapered end mill compatible with standard 5\/16 inch collet and end mill holding systems on CNC machining centers and conventional milling machines.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before inserting or removing the tool from the holder. Verify collet or holder bore matches the 5\/16 inch shank diameter before tightening. Inspect the cutting edges for chips or damage prior to each use, and confirm runout is within acceptable tolerance 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: 3\/32 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: 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\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\u003eCenter Cutting\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: 12177521\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51741600809266,"sku":"12177521","price":119.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cf26d98f6dbdf616ba63426f8b5c8268.jpg?v=1788832405","url":"https:\/\/voomisupply.com\/products\/accupro-12177521-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
