Drill and drive apparatus having arrangement to accommodate long drill bits
摘要:
A drill and drive apparatus includes a tube assembly which defines a tool chamber, the tube assembly including a shank adapted to be received within a chuck of a drill. The apparatus further includes a tool holder which is configured to be at least partially received in the tool chamber of the tube assembly, the tool holder having (i) a first tool locking mechanism at a first end portion thereof, and (ii) a second tool locking mechanism at a second end portion thereof. The drill and drive apparatus further includes a tube locking mechanism which is configured to releasably lock the tool holder to the tube assembly when the tool holder is at least partially received in the tool chamber. The shank defines (i) a first shank opening, (ii) a second shank opening, and (iii) a bit passage extending from the first shank opening to the second shank opening, whereby a drill bit locked to the tool holder by the first tool locking mechanism may extend through the first shank opening, the bit passage, and the second shank opening when the tool holder is locked to the tube assembly.
