The patent pending made in the USA Hollow Roller™ system is a captive bar tool for safely turning hollow forms and bowls. The bar is completely captive, which allows the operator to focus on the work and art of the vessel being turned instead of on the complexity of the hollowing system. It incorporates a fully sealed bearing lubrication free roller system that eliminates drag on the bar, thus enabling a smoother flowing motion to all tool movements. By doing this, it gives the operator more control and feel while turning the work piece.
