Hi guys, my Dewalt DCD796D2-QW is not drilling perfect circular holes any more. When I insert a drill bit in the drill chuck, the drill bit is rotating in an oval shape.
Since it’s not of the drill bit (I’ve tested with several drill bits, and in the drilling machine they are all ok), it must be from the drill chuck.
Now, does anybody know how can I remove it to change for a new drill chuck?
Do I need a special key?
Here’s a photo of it
