How many size of drill bits?

Purchased June 2022: smallest 3/32, middle 7/64, and largest 1/8. Sizes are stamped on side of each piece.

want to know what the quick change is?

Clic-change is a GIMMICK. It is present on 100% of all quarter inch hex drill bits, driver bits, literally any quarter inch hex tool for a drill or driver. Since the '90s. Shame on Bosch for this advertisement.

Are the drill bits replaceable (in case one breaks)?

Each of the three self centering drills have allen set screws on the side of each unit that allow the drill bits to be removed and replaced. I use these drill bits all the time. It is easier and more accurate to drill a centered starter hole using these bits than trying to eyeball a hole and find out that it is not centered. Fast, accurate and easy to use. And I believe that the small drill bit is used is each of the drills.

Are the drill bits tapered ?

The drill bit themselves are straight, like any 'normal' drill bit. The size 6 is 3/32; size 8 is 7/64; and size 10 is 1/8" diameter. The tip of the housing is slightly tapered to facilitate centering, such as in the hole of hinge.
