Impact Action: Provides a rotational "hammering" force (tangential to the rotation) that kicks in when resistance increases. This prevents stripping screws and wrist strain.3

Purpose: Driving fasteners (screws, lag bolts, deck screws).4 Not ideal for drilling holes, especially large ones.

Chuck: Features a quick-change 5$1/4 \text{ inch}$ hex chuck that only accepts hex-shank bits.
