Milwaukee m18fpd2 damaging bits

[MonkeyP]

Hi guys,
New to the forum as needed help that no one has been able to answer. I have a Milwaukee M18fpd2 and I have noticed that its damaging the shafts of all my drill bits, even the cobalt ones. It pushes the metal to one side causing a little divot from where the metal has moved and the ridge to where the metal has moved to.

Previously the jaws in older drills have been flat or had 2 outer edges to hold the drill bit true but the Milwaukee seems to have one row of one ridge on each jaw which damaged my drill bit. I have taken pictures on the damage on a new bit and the jaws.

I have already sent it back once as the chuck wobbled so had that fixed already.

Any help would be much appreciated.

Look's like you've found a design fault

Under tightening would cause this.

Tighten chuck by hand nice and tight. Turn back and chuck clicks.
Now locked.
Works will all drills I've used. Not everyone knows

Yes that is something I discovered only fairly recently. My old mains drills never had a chucks like that but a couple of battery ones I have bought recently have this feature on the chucks. Chuck keys seem to be a thing of the past.
