A quick-change drill chuck adapted for positioning ball elements within dimples circumferentially disposed about the central axis of the adapter portion of a tool, such as a drill, to drive the drill. A first quick-change drill chuck utilizes an axially spring-biased collar, while a further quick-change drill chuck incorporates a rotary spring-biased collar for manipulating the ball elements into and out of the dimples.

A cylindrical shaped tube freely rotatable within a housing provides the pressure chamber for an eccentrically mounted rotary seal vane type pneumatic motor with the drive actuating air moving axially through the pressure chamber.

A drill stop having a dimple arranged so that the drill stop can be utilized after the drill has been ground to a shorter length. A cylindrically shaped tubular member is provided with a dimple off center with respect to the longitudinal axis which dimple provides an interference fit in the drill flute along the run out ramp portion of the flute adjacent the shank end of the drill. A further dimple opposite the first dimple may be utilized to reinforce the function of the first dimple.

Double ended drill stop

A lubricator for an automatic riveter positions an absorbent pad containing a liquid lubricant in the path of the riveter's drill bit when the bit is being moved laterally. The absorbent pad is resiliently held to ensure contact between the pad and the drill bit. When drilling only, the pad is mounted at an angle to a cylinder and is driven back and forth by the cylinder to contact the drill bit and transfer lubricant.

Lubricant applicator

A housing to fit over a drill contains a pair of sleeves with facing inclined surfaces that approach each other to force a washer located between the surfaces into an inclined position to lock onto the drill. A spring located on each side of the washer extends to the adjacent sleeve.
