What is a magnetic bit holder?

	This type of chuck has a magnetic bit holder built into its design.
	The bit holder has a powerful magnet at the base that holds the bit in place.
What bits can it accept?
	Magnetic bit holders always have a hex slot, which means they can only accept bits with a hex shank. In order for a screwdriver or drill to sit securely in the chuck, it must be the right size. Read more about this in our section: What is cartridge size?

Disadvantages of a no deposit bonus
	Compared to a keyless chuck where the bit is held by a magnet and ball bearings, a magnetic bit holder uses only a magnet. As a result, it doesn't hold the bits as securely, and you may find that if you buy a poor quality model, the bits can wobble or even fall out.
