What occurs when the drill bit is not seated properly in the pilot hole before activating the drill?

When the drill bit is not seated properly in the pilot hole before activation, the phenomenon that occurs is known as drill wander. This happens because the bit may not be aligned correctly within the opening and can move or slip away from the intended drilling path when torque is applied. The correct term is typically described as "drill walk or drill wander," as the bit may skid across the surface rather than drilling straight down into the material.

In this situation, if the drill is activated with the bit improperly seated, it can cause inaccuracies in the drilling position, leading to misalignment and potential damage to both the workpiece and the tool. Proper seating of the drill bit is crucial to ensure the drill starts in the correct position and that there is minimal risk of slippage or wandering during the drilling process.

The mention of "drill run and drill start" does not accurately capture the issue at hand, as this suggests the operation begins without addressing the misalignment problem that could lead to improper drilling. Therefore, focusing on securing the drill bit properly is essential for ensuring effective and accurate drilling operations.
