Whether you're just milling some boards to patch or add to an existing floor, or you want more control over the color match and strip width of a new floor, our flooring bit set is the perfect candidate. The cutters are specially designed for flooring, and feature chamfered edges along the tongue and along the bottom edge of both boards. This prevents small particles such as sand and sawdust from affecting the fit of your strips. The bevel on the bottom edge also ensures that the joints will be tight even if there is a slight hump in the sub-floor. A V-groove nail slot in the male section helps your nails set in nicely so they won't interfere with the fit.
