The main difference between a drill and an impact driver boils down to power and rotational action. Unlike drills, impact drivers are made with quick release shanks that accept all one-quarter-inch hex driver bits. Impact drivers produce lots of rotational force, capable of driving the largest wood screws in seconds.
Why do my drill bits go blunt?
Applying too much or not enough pressure – Too much pressure can break the bit, and not enough pressure can blunt the bit.
