Hi,

Am new here and bough my first Bosch professional cordless drill 18v combi.

I am wondering is it normal for the chuck to wobble slightly even th drill bit or driver bits does have a slight wobble. I know the chuck sleeve does wobble but the drill bit and driver bit do too.

Look forward to replies.

Concentric runout as it's called simply isn't acceptable in a new, professional standard tool.

However, before sending it back, just ensure that the chuck is actually correctly seated on the spindle.

There's a left-handed screw accessible inside the chuck by opening it fully.  Ensure it's tightened.

Don't try to actually remove the chuck, as some later versions, stupidly, have a one piece chuck and spindle assembly.  There should be instructions in your tool's manual.

If you don't have any luck with this procedure, then send it back for replacement.

 I took it back to where i got it from they said it normal for a little movements?  Surly for a kit a this price we expect it good.

I asked to look at several others while instore and come to my shock they all did the same

Bosch Pro 2 more same as mine
Dewalt
Makita
Metabo

All had the same thing hmmmmmm

Hi,
Not exactly the same problem but I have a gsb18ve2li which has had a problem from new.When you install a drill bit it usually come loose.Even when you lock it as it says on the chuck the bit comes loose.I have had to use hex ended bits but as they are not very popular are hard th get hold of.Is there a problem with the chuck?
Thanks Al.

Hi all.

Andrew
There will be a very small amount of movement with the chuck both backwards & forwards as that is needed for the impact/hammer action and because of this there will also be movement in all directions. However there is a tolerance to what is acceptable. It does vary slighty from machine to machine. What 18V combi do you have?

Alan
The bit should lock in and chuck should NOT loosen if tightened correctly. I assume this is an autolock chuck on the drill. It is either not being tightened enough or faulty.  Sounds like it is faulty.

Its hard to answer both these questions without seeing them. Andrew's drill is probably within tolerances and if you want a drill that has no movement you are likely to be wanting a precision drill such as a GBM. These do not have impact/hammer for the reasons above and are corded.

Alan. If the chuck is not holding I would recommend having it looked at. If under warranty still that should be fixed no problem.

 Hi All

Have had the drill checked out and it withink Tolerance so am happy now as got use to it

hi lads
I would not expect or accept any runout on any new tool if its visible with the naked eye its wrong
if you were drilling a 2mm hole with runout you may get 2.2or even 2.3mm in my booh totally un acceptable
the only time i would accept runout would be using an older sds model with a chuck adapter

sort it out bob
andy

To be honest I did not want to accept it but I took it back to the store where i bough it from where we took out 5 more machine the same they all did same thing...

Took out 3 dewalt and they did it
Took out 2 metabo and they did it

So i though must be normal
