ABSTRACT:
A router depth adjustment mechanism for minimizing rapid course depth adjustment for standard and plunge routers. Routers with rapid or course adjustment mechanisms may permit a router motor housing to drop suddenly, if the user is inattentive. Sudden adjustments may result in damage to the router and potentially contact the user. The mechanism of the present invention includes a threaded shaft and a biased thread engaging member which may be disengaged for rapid adjustment. A restraining device and/or a break may be included to minimize the rate of change.
