Most of the holes of panel furniture parts are processed by various types of dowel drill bit, which are divided into single dowel drill bit, multi dowel drill bit, three-side dowel drill bit, six-side dowel drill bit and so on.

According to the direction of rotation, the drill bit is divided into forward rotation and reverse rotation. When installing, remember not to install it backward.

Forward and reverse are made into different colors of red and black. Red represents reversal, usually represented by "L", and black represents forward rotation, usually represented by "R".

CNC side hole drilling machine, power drills and other equipment are mostly used for forward rotation, and the two hidden holes next to the hinge machine are generally used for reverse rotation. However, there are forward and reverse rotations on the row drill machine, so make no mistake.
