A quick-change attachment configuration is directed to a tool for use with a hole saw for boring holes on a wooden plank, particularly the quick-change attachment configuration is arranged for quickly replacing a longitudinal body, which is a drill bit shank having a driving end, a tool end, and a limiting portion. The configuration includes a quick-change attachment for assembling a longitudinal body and a hole saw which has an axial hole for allowing a longitudinal body to move on the quick-change attachment, and a locking component for locking and releasing the longitudinal body on and from the quick-change attachment. The locking component has a first component and a second component, which when used, the longitudinal body is easily moved slidably and locked so the shreddings emerging from the hole saw are cleaned.
