The unique Box Hollower is specifically designed for hollowing projects with straight sides and flat bottoms. It is ideal for boxes and can also be used on larger projects, like tall vases. Its broad cutter facilitates the rapid removal of waste wood. Because the shank is a full ¾" flat section, there is no fear of tool rotating inside.The cutter may also be slightly off-set to give a different angle of approach. There are other cutters which may be fitted to this tool, see table on right. Sharpening is done with a diamond file or honing stone and can be achieved on the tool or by using the 472. Blade Length: 5-1/2"
