Not expensive and readily availableIf only I had a 2MT collet chuck...

Here's an option I've used for keyed chucks which works a treat, and great for use as file handle's also. Golf balls, drilled 3/4 the way through and slightly undersized. The rubber core grips tight, but wear safety glasses while drilling as occasionally one might encounter an old one with a liquid core under pressure which can squirt out with some force.After a lifetime of nipped fingers from badly fitting keys, I haven't got a single keyed one in use. I strip the keyless chucks ,clean and molylube.
I do the golf ball thing tooHere's an option I've used for keyed chucks which works a treat, and great for use as file handle's also. Golf balls, drilled 3/4 the way through and slightly undersized.

Now you are going to tell me that’s on par with a keyless chuckHere's an option I've used for keyed chucks which works a treat, and great for use as file handle's also.

Not totally as you can get away with your hand for most drills etc.Saw that in my feed too. Interesting idea but overengineered for the task. Defeats the object of having a keyless chuck too.
Cool idea,
Why the knurling on the outer face, it's not going to be in contact with the chuck?
Grip for oily fingers ?Why the knurling on the outer face, it's not going to be in contact with the chuck?
