4 ” Z 1 W / S C O R E D R I L L o Ø NOTE: During the initial stages of contact the bit may wander. After about 1/8” of cutting has been achieved in the work surface, slightly more force can be applied. This will be the normal amount of force the rest of the hole. o NOTE: Do not force the hole. Let the machine do most of the work. Excessive physical effort should be avoided as it can cause damage to the machine or the user.
