Dremel is my new god

[Shrub]

Small chucks are usually way out of line if you dont spend the money for a quality item, collets are for that purpose, to run the cutters perfectally true (although even some very cheap collets dont run true!!) a chuck is totally fine in other uses but on a dremel running as fast as it does it could damage the bearings and actually cause any bits to break up sooner and cause the tool to be more dangourus as it is anyway in the wrong hands,

That said, it is a very good idea and one i often use in other applications, if you can make sure your chuck is on alignment be it with a dti or just line of sight and there is no vibration when the unit is switched on then go for it,

Not scare mongering just making sure you all know the pros and cons,

Shrub, the chuck I used was a dremel branded one and absolutely no problems.

The more expensive dremels are coming out with chucks as standard anyway, so it looks as if they may have ironed out any concerns you might have had.

It was expensive £16. but I found it well worth it. I think you can buy it cheaper on the net.

If you have a look on Pyro's dremel video you can see one.

£16 sounds good,

Yes i was generaliseing a little and was going off experiances with small lathe/pillerdrill/millingmachine chucks and a dremel branded one will as you say be perfectally ok, its the 50p market types that i was leaning more towards,

I agree a chuck in a collet system is great for speed and non critically acurite work (which you cant do with a free hand tool anyway),
