All sizes of Dot style and Turbine style NamPower disc brushes are designed for use with NamPower tool holders with flow through coolant galleries. The 16mm precision ground shank allows coolant to flow from the brush center. This results in better lubricant dispersion which permits the brush to run at greater cut depths and drastically reduces heat generation. 50mm, 60mm and 80mm brushes are designed to work with the 16mm shank tool holder. The product on this page is the 16mm shank variant.
100mm, 125mm and 150mm brushes are designed to work with the larger flow through coolant NamPower tool holders with 25mm shanks. Please contact us if you would like to purchase either the standard or sidelock 25mm diameter shank holders.
