Bowl gouges are designed to be strong and remove wood quickly relative to the size of the tool. Unlike spindle gouges the flute is U shape or V shape with a radius at the bottom of the V, this enables the efficient removal of shavings. They are made from round section stock giving them the strength required for the job of overhanging the tool rest when producing deep bowls. Typical sizes range from ¼” (6mm) to 1” (25mm) 1” being less typical than the rest. Most turners will have more than one bowl gouge due to having to have different bevels to suit certain shapes and designs. Some gouges may be of the traditional grind where others may have fingernail or swept back sides at the cutting edge. Experience will help decide the tools required for the tasks in hand.
