Major Manufacturing HIT-66-200 Lock Mortiser. Our new HIT-66-200 lock mortiser can quickly mortise a pocket for a mortise lock. The mortiser requires the use of our HIT-66 clamp system (sold separately) and can be used with most of our HIT-66 templates at the same time. The mortiser includes a 1 carbide tip mortise bit, mortise guide plate for alignment and stop collars. Once the unit is clamped to the door, it is a simple matter to set the height and depth stops. A series of holes can be drilled then the webs between the hole can be wasted away forming the pocket. Requires the HIT-66 clamp set and a 1/2 drill motor.
