With a 5-degree taper per side and a 1\/4 inch small end diameter, this tool produces accurate tapered walls and angled features in a single pass. The 3-flute spiral configuration with a 30-degree helix angle promotes efficient chip evacuation while maintaining a smooth surface finish. Micrograin carbide construction provides the hardness and wear resistance needed for demanding cuts in ferrous and non-ferrous materials. The bright uncoated finish makes it well-suited for applications where coating interaction with the workpiece is a concern.\u003c\/p\u003e\u003cp\u003eThis end mill is used in CNC machining centers and manual mills for creating draft angles, tapered pockets, dovetail lead-ins, and mold or die work where precise taper control is required. The square end geometry allows flat-bottom entry and side milling along tapered walls. With a 1 inch length of cut and a 2-3\/4 inch overall length, it is sized for moderate-depth work in both production and job-shop environments. The 7\/16 inch shank fits standard ER and side-lock toolholders common in vertical and horizontal machining setups.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e5-degree taper per side for precise angled wall geometry\u003c\/li\u003e\n\u003cli\u003eMicrograin solid carbide construction for extended tool life and edge sharpness\u003c\/li\u003e\n\u003cli\u003e3-flute spiral design with 30-degree helix angle for efficient chip removal\u003c\/li\u003e\n\u003cli\u003eCenter-cutting capable, allowing direct plunge entry\u003c\/li\u003e\n\u003cli\u003eRight-hand flute direction compatible with standard spindle rotation\u003c\/li\u003e\n\u003cli\u003eBright uncoated finish suitable for a wide range of workpiece materials\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 using 7\/16 inch shank toolholders, including ER collet chucks and side-lock holders of the appropriate bore size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis tool should be installed by a qualified machinist or CNC operator following the machine tool manufacturer guidelines for tool holding and runout tolerance. Ensure the spindle and toolholder are clean and free of chips before seating the shank. Confirm proper collet size or holder bore before tightening to the manufacturer-specified clamping procedure. Always verify spindle rotation direction matches the right-hand flute orientation before initiating a cut.\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: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2-3\/4 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\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: Bright\/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: 12177531\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51742860476722,"sku":"12177531","price":113.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/bda9e6da00009a5c56f54a1bef6558ac.jpg?v=1788839929","url":"https:\/\/voomisupply.com\/products\/accupro-12177531-tapered-end-mill-3-flute-solid-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
