A universal tilt base accommodates general-purpose router motor housings with diameters of 3-+E,fra 1/2+EE inches and larger. The motor housing is received by a collar tiltingly attached to a table base with an aperture, so that when a cutting bit attached to the router motor, the bit protrudes through the aperture to effect a workpiece, with means to independently adjust both the depth and tilt angle of the cutting bit. In the preferred embodiment, the collar is configured to accommodate router motor housings which either slide without rotation to adjust cutting depth and those which may be rotated during depth adjustment. To accommodate at least two of the types which do not rotate during depth adjustment, the collar is configured to receive motor housings having an at least one outward protrusion. A plurality of grooves, formed lengthwise and spaced apart on the inside cylindrical wall of the collar, may further be provided to accommodate motor housings having a plurality of spaced apart outward protrusions which slidably engage with the grooves. Means are also provided to compress a separation in the collar to secure the motor housing in position with a cutting bit attached thereto so as to bring about a desired cutting depth in the workpiece.
