Drill bit that won't come off an electronic driver?

I have a Black & Decker electronic screw driver and a set of various drill/driver bits. I have no problem using driver bits with my electronic driver, but whenever I use a drill bit to drill a hole in the dry wall, the drill bit comes off the electronic driver at the end. It's not a big deal, but it's definitely an inconvenience as I have to pull out the drill bit from the wall with my hand each time.

Is there a drill bit that won't come off an electronic driver? Alternatively, are there electronic screw drivers that won't lose a drill bit? I've noticed that unlike driver bits, drill bits have shallow "waist" at the end that may prevent the issue I'm facing. My Black & Decker electronic driver doesn't have any special feature that can utilize this "waist" but maybe some other drivers do.

You don't say what model of screw driver you have. What type of chuck does your drill/driver have?

Cordless screwdrivers usually have just a magnetic straight hex receiver that holds the bit. They are not really intended to be used as a drill......they simply don't have the needed RPM.....and....as you have found out.....they don't have a locking mechanism that would hold onto a hex shank drill bit.

You can get a small combo drill/driver with a spring loaded hex "chuck" if you want a dual purpose tool.

As Halton predicted, mine just has straight hex receiver without any chuck I believe.

I much prefer the flexibility and handle shape of a cordless drill. You can get magnetic bit holders that you chuck up and can hold your hex bits for quick tool changes.

I went to the local Home Depot to check out one of these. It looks like at least the ones that I saw have a lock-in mechanism by throttling the receiver with brute force. It doesn't seem like there is any chuck involved. Is this how they are supposed to be?

I think you are describing a keyless chuck, pretty common on cordless drills.

Cordless screwdrivers should work the same way as cordless impact drivers.
The collar should slide rearward allowing your bit with a circular groove to be retained.

Do your bits have this groove?

A chuck like this one should do the trick.

Yes, all of my drill bits have groove. Driver bits are groove-less.

Is there a retaining collar on the drill and is it not gripping the bits?
The locking collar should retain the bits.

To engage a locking collar you would pull (back or out depending on the direction of your tool) on the knurled ring and while back insert the bit and release the ring.
Does yours not do this?

The bit that is pictured is referred to as a ball detent and the one inch long driver tips are called wire detent.

The bits themselves can have groove for the ball detent. If y

Some quick-release chucks do a pretty good job of locking onto the small cut in the wire-detent bits, as well as the ball-detent ones. Try them in the store if you can.
