Como Cambiar el Mandril a tu Taladro

The video explains the different types of chucks on the market, their different mounting threads on the shaft, and the two left-hand screw thread sizes used to secure the chuck to the shaft so that it does not loosen when used in reverse. One method of chuck removal is explained in case of a repair or for any case in which the chuck cannot be closed, since it is difficult to close the chuck with the chuck's own adjustment key in one of its three holes to close its jaws. It also explains how to check whether the drill has a left-hand screw inside the chuck (as not all drills have one). If it can be removed because its head is stripped, it must be removed using another drill or a multi-tool (commonly known as a mini-lathe) to perform this task. If for some reason these methods cannot be used because the chuck is unusable, more "heavy-duty" methods will have to be used, such as using a grinder or emery to remove it from the tool, or even removing the shaft from the machine to perform the operation more safely.
