Abstract
A rotary-vibratory drill coupling has a first component with a plurality of spaced-apart members. Each member has a pair of opposed, spaced-apart faces defining a slot therebetween. A second component has a plurality of angularly spaced-apart blade-like projections extending radially thereon. Each of the projections is slidably received between one pair of the opposed, spaced-apart faces on the first component. Preferably there are anti-friction linings between the projections and the faces.
