Assess Damage and Attempt Initial Extraction

What happens here

The video introduces a DeWalt 20V MAX XR cordless impact driver with a screwdriver bit broken off and deeply stuck inside the chuck. The narrator explains that the bit is very low and won't eject. He attempts to remove it first with needle-nose pliers, then with Vise-Grip pliers, trying to wiggle and pull, but only manages to break off more fragments of the bit. He notes a strong smell of Kroil oil, indicating previous attempts to free the bit.

Goal: Understand the problem and try basic bit removal methods.
