The Tapered Spoon Bit

The tapered spoon bit looks a lot like an upside down cone is used by chair makers for boring tapered holes in the seats and arms of chairs. When boring into solid wood, the bit should be started in a straight position and after a hole has been made and the bit has begun to drill into the wood, the angle of boring can be changed by tilting the brace and bit until the desired angle is reached. This will enable you to bore a tapered hole at any angle.
