It features a 0.5-degree taper angle per side with a 1\/8-inch small end diameter and a 1\/2-inch length of cut. The ball end geometry with a 1\/16-inch nose radius allows smooth finishing passes in molds, dies, and sculpted workpieces. Built from micrograin solid carbide, it delivers rigidity and wear resistance in demanding CNC machining applications. The uncoated finish suits a range of materials where coating buildup or heat sensitivity is a concern. This tool is installed and used by machinists and CNC operators in production and job-shop environments.\u003c\/p\u003e\u003cp\u003eThis tapered ball end mill is suited for 3-axis and multi-axis CNC milling machines handling detailed contouring, rib milling, and finishing operations in mold-making, die work, and precision part manufacturing. The 3\/16-inch shank diameter fits standard collet systems. Its right-hand flute direction and 30-degree helix angle promote smooth chip evacuation during finish cuts. The 2-inch overall length provides adequate reach for moderate-depth cavity work without sacrificing rigidity.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMicrograin solid carbide construction for rigidity and extended tool life\u003c\/li\u003e\n\u003cli\u003eBall end geometry with 1\/16-inch nose radius for smooth 3D contour finishing\u003c\/li\u003e\n\u003cli\u003e0.5-degree taper angle per side for tapered wall and draft-angle milling\u003c\/li\u003e\n\u003cli\u003e3 flutes with 30-degree right-hand spiral helix for efficient chip evacuation\u003c\/li\u003e\n\u003cli\u003eCentercutting design allows plunge entry into the workpiece\u003c\/li\u003e\n\u003cli\u003eUncoated finish suitable for a broad range of workpiece materials\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and manual mills equipped with collet systems accepting a 3\/16-inch shank diameter.

Power down and lock out the spindle before loading or unloading the tool. Secure the 3\/16-inch shank in a clean, properly sized collet or end mill holder and tighten to the machine manufacturer's specified torque using the appropriate wrench. Inspect the cutting edges for chips or damage before each use, and confirm runout is within acceptable limits before beginning 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\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 3\/16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2 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\u003eNose Radius\u003c\/strong\u003e: 1\/16 inches\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: Ball\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: 12177555\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ACCUPRO","offers":[{"title":"Default Title","offer_id":51732142227762,"sku":"12177555","price":174.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/09ca65d9278d4cc97a13aa016e0423f9.jpg?v=1788739673","url":"https:\/\/voomisupply.com\/products\/accupro-12177555-tapered-ball-end-mill-3-flute-carbide","provider":"Voomi Supply","version":"1.0","type":"link"}
