A removable depth guide assembly for a cutting tool of the type having a housing containing a motor connected to a collet for rotating the latter about an axis, said assembly comprising:
- (a) said housing including engageable means adjacent said collet;
- (b) a depth guide having a first part including engaging means adapted for interengagement with said engageable means when said first part is rotated relative to said housing in a first direction in a plane perpendicular to said axis for detachably securing the first part to the housing, rotation of the first part relative to the housing in a second direction opposite said first direction serving to disengage said engaging means from said engageable means thereby permitting separation of the first part from the housing;
- (c) said first part including a first support element;
- (d) said depth guide including a second part having a second support element engageable with said first support element;
- (e) fastening means engaged with said first and second support elements for adjustably positioning said second part relative to said first part in a plurality of locations along said axis;
