Built with a 3.00-degree taper angle per side and a 6-degree included angle, this tool delivers accurate tapered wall geometry in a single pass. The 0.1250-inch mill diameter at the small end transitions from a 0.1875-inch shank, with a 0.3750-inch length of cut and a 2.0000-inch overall length. The 4-flute, variable-pitch spiral design reduces chatter and promotes chip evacuation. Applied APLUS coating extends tool life in ferrous and non-ferrous materials. Centercutting geometry allows plunge entry. Installed by machinists and tool-and-die professionals in CNC milling applications.\u003c\/p\u003e\u003cp\u003eThis tapered ball end mill is suited for 3D contouring, die and mold work, draft angle milling, and deep-cavity finishing where a tapered tool path is required. The 3.00-degree taper per side makes it appropriate for creating draft angles in injection molds, forging dies, and precision aerospace or medical components. Right-hand flute direction is standard for conventional CNC spindle rotation. The tool ships as a single unit and is intended for use in CNC machining centers with appropriate collet or end mill holders sized for a 3\/16-inch shank.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSolid carbide construction for rigidity and wear resistance in demanding milling applications\u003c\/li\u003e\n\u003cli\u003e3.00-degree taper angle per side (6-degree included angle) for precise draft and taper geometry\u003c\/li\u003e\n\u003cli\u003e4-flute variable-pitch design reduces harmonic chatter during full-depth cuts\u003c\/li\u003e\n\u003cli\u003eBall end shape enables 3D contour and radius milling at the tool tip\u003c\/li\u003e\n\u003cli\u003eAPLUS coating improves surface hardness and heat resistance for extended tool life\u003c\/li\u003e\n\u003cli\u003eCentercutting capability allows direct plunge entry without pre-drilling\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use in CNC machining centers and milling machines accepting a 0.1875-inch (3\/16-inch) shank diameter via collet chuck or end mill holder.

Ensure the spindle is fully stopped and locked out before inserting or removing the tool from the holder. Use a properly sized collet or end mill holder rated for a 3\/16-inch shank to achieve full grip and minimize runout. Follow the tool manufacturer and machine OEM guidelines for feeds, speeds, and depth-of-cut limits for carbide end mills in your workpiece material.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMill Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSmall End Diameter\u003c\/strong\u003e: 0.1250 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShank Diameter\u003c\/strong\u003e: 0.1875 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength of Cut\u003c\/strong\u003e: 0.3750 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.0000 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTaper Angle Per Side\u003c\/strong\u003e: 3.00 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Angle\u003c\/strong\u003e: 6 degrees\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Flutes\u003c\/strong\u003e: 4\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Shape\u003c\/strong\u003e: Ball\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Type\u003c\/strong\u003e: Spiral, Variable Pitch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlute Direction\u003c\/strong\u003e: Right Hand\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Mill Material\u003c\/strong\u003e: Solid Carbide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating\/Finish\u003c\/strong\u003e: APLUS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCentercutting\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: HELICAL SOLUTIONS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 84874\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HELICAL SOLUTIONS","offers":[{"title":"Default Title","offer_id":51732663042354,"sku":"84874","price":53.73,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6a76c2492eea61f62fd9f87a3b5d7ad4.jpg?v=1788745477","url":"https:\/\/voomisupply.com\/products\/helical-solutions-84874-tapered-ball-end-mill-4-flute","provider":"Voomi Supply","version":"1.0","type":"link"}
