This frustrating situation occurs when the rotating force of an impact driver fails to dislodge a fastener, instead binding the bit within the driver’s chuck. This can happen for several reasons, such as a stripped screw head, excessive torque, or a bit that is the wrong size or type for the fastener. A common example is a Phillips head bit camming out of a stripped screw, becoming wedged in the driver.
Addressing this issue is crucial for several reasons. Continued force can damage the driver, the bit, or the workpiece. Moreover, a jammed bit halts progress and can necessitate costly repairs or replacements. Historically, removing stuck bits often relied on brute force methods, which could exacerbate the problem. Modern techniques and tools offer more effective and less damaging solutions.
