Speeds up the process of using a Dremel

It is really a pain in the neck to keep pulling out that little tiny Dremel wrench to swap one Dremel mandrel for another. The Dremel Chuck allows you to quickly grasp and release the mandrels using just your hands. You can also use the wrench on it to make sure your mandrel is held tightly, but most of the time , hand tight is sufficient. There are some function that this chuck is not recommended for due to speed, torque, and force, so be aware of this when inserting tools. ==> Homw Power Tools
