SETTING UP BOLT PLATE LENGTH:
The Commander is capable of machining bolt plates 2” to 12” long. To adjust the bolt
plate length simply adds or removes telescoping spacer pins as required. Make sure
that the same amount of spacer pin is added to both the left and right sides.
LOCK BORE TWO STAGE FACE DRILLING:
It is possible to drill two different diameter holes with the same cutting tool. The
drawing represents a 2-1/8” counter bore bit mounted on the shank of a smaller
diameter bit. Care must be taken that the 2-1/8” be maintained between the tip of the
ring cutter teeth and the teeth on the main cutter or door face tear-out will result.
Turning the selector switch to REG allows the smaller bit to drill through the door but
not so deep that the counter bore touches the door. Deep sends the counter bore all the
way through the door until it just etches a groove in the chip out block.
It is important when switching from 1-3/8” doors to 1-3/4” thick doors that you use the
proper shims to make the difference up between the two door thicknesses. There is a
pin holder located next to the lock bore motor that engages the two limit switches
which dictate where the cutter stops its movement in the door.
The pin holder holds a 3/16” pin, ½ the difference between the two door sizes by
adding the 3/16” pin when machining a 1-3/8” door; it will limit the travel so you don’t
destroy the chipout.
The side drill bit has a 4” long fluted section. For 5” backsets and over bored dead-
bolts you’ll need to put in a 6” bit. Be certain the machine is locked out.
