Most of National Flooring Equipment's grinders fit Fast Change Tooling. This wedge-shaped grinder tooling is available in a variety of segments, bonds, and grits. Double-bar metal bond tooling is an industry staple and a great option to keep in your toolkit. 

A double-bar segment is less aggressive than a single bar and will leave a smoother surface profile. Fast Change double bar segments fit National's 8274-4, M600, P650, M800, and P800 planetary grinders.
