3PCS Sphere Rotary Burr, 360° Sphere Rotary Burr,5/8-11 Thread Ball Gouge Attachments for 4-1/2" & 5" Angle Grinders Carbide Steel Power for Wood Hollowing, Slotting, Engraving

Feature:【Complete 3-Size Sphere Burr Set with Precise Specs】This chainsaw carving tools includes 3 spherical rotary burrs (25mm/0.98", 30mm/1.18", 40mm/1.57" diameters) with 5/8"-11 universal threads. Made of high-density carbon steel, these burrs maintain sharpness through extended use while withstanding speeds up to 12,000 RPM. The graduated sizes allow progressive shaping from rough carving to fine detailing.【Direct Installation on 4.5" & 5" Angle Grinders】Designed for seamless compatibility with standard angle grinders, sphere rotary burr set directly onto 5/8"-11 spindle threads without adapters. The unified threading system ensures vibration-free operation at all speed ranges. Ideal for both dry and wet woodworking applications.【Aggressive Cutting Action for Efficient Material Removal】Features hundreds of precision-aligned carbide teeth that rapidly hollow, contour, and shape wood while maintaining smooth surface finishes. The spherical geometry provides 360° cutting action for creating bowls, sculptures, and complex curves without tool repositioning.【Optimized for Softwood Carving & Detailing】Excels in beech, pine, spruce, linden, and other softwoods. Perfect for rough shaping, hollowing, undercutting, and final surface blending. The balanced design prevents gouging while allowing freehand artistic expression and efficient stock removal.【Safety-First Design with Professional Guidance】 Always use with OSHA-certified goggles, respirators, and gloves. Pre-scan wood for metal contaminants to prevent hazardous kickbacks. The flange lock system ensures secure operation during extended sessions.Specifications:Material: 45 SteelSize: 40mm diameter grinding head: 4*10.8cm, 30mm diameter grinding head: 3*10.3cm, 25mm diameter grinding head: 2.5*10.2cmPackage Includes:3xSphere Rotary Burr
