The jig is clamped onto a door to cut a mortise for the fitment of a door lock.
A drill is attached to the jig with the following requirements:
The cutting length and depth of cut can be adjusted to comply with the demands of
various door lock sizes. The standard cutter supplied with the jig is a Ø17mm.
