LOCKING RANDOM ORBITAL DUAL-ACTION HEAD ASSEMBLY WITH CENTERING
摘要
<p>A removable head assembly for a combination rotary, including: a body; a rotatable element connected to the body and including an indentation or protrusion for fixing a pad assembly to the rotatable element; and a locking assembly including first and second elements. The body is connectable to a combination rotary tool and is rotatable about a first axis; the rotatable element is rotatable about a second axis; the indentation or protrusion is aligned with a third axis substantially parallel to the second axis; and the first element is displaceable to displace the second element to rotationally fix the rotatable element with respect to the body so that the first and third axes are co-linear, and the second axis is out of alignment with the first and third axes.</p>
