Is your collet suppose to be very difficult to loosen enough to get the bit out. I've seen people change bits in videos and looks like a quarter turn of the wrench and the bit almost falls out. I seem to have to make 4-5 complete turns before I can get the bit out. I am using a dewalt 618 in a rockler plate if that matters.

I don't know about the DeWalt system but the Makita 3612c and the Bosch MRC23EVSK system bit release is easy, for me maybe one full turn of the one(Makita) or two wrenches (Bosch).

The dw618 has a catch that you have to loosen and then turn a little more and it tightens up, then you turn a little more to loosen. This is normal. I think it is built in as a fail asfe to keep the bit from coming loose while the machine is running. Don't know if this makes since to you but it is normal.

My PCs and Boschs require less than a full turn to loosen the collet so it can be finger turned. Then, after a few finger turns, all the PCs need the wrenches to get past a second tight spot before the bit can be removed.

It also allows you to insert bit, partially tighten, lift bit 1/8" and it will stay in place while you completely tighten

Too bad there are no auto spindle locks so you only need one hand to change. The button to release on the 618 seams to always be blocked and ther isn't much room for 2 wrenches in theer

I agree with Steve. I thought something was wrong with my DW618 until I asked the same question as you.

This has been the case on several European routers I've owned. It doesn't stop the bit from coming loose in the chuck, but it can't fly out. The Porter Cable I now use in my table doesn't have that facility.

My Hitachis are the same as Steve`s, Gene`s, and the others. You have to loosen twice.

Jon is correct that the Musclechuck is the only one handed type available. It tightens with an allen wrench and only requires one quarter turn and it reportedly holds more securely (4x) that a standard collet. It was developed by John DeRosa who is a member of the forum and he was giving forum members a discount in the past and may still be.

My Ridgid has that second bite, that most are talking about. But 4 or 5 turns seems to be a bit much. I think even with the second catch, it's still no more then a turn or two.

Can't beat a Muscle Chuck. Have one on my Ridgid table mounted router. On the handhelds, I don't mine using the two wrenches or the spindle lock and one wrench.

I've got a hitachi, dewalt and worx (cheap brand) but all have the 'loosen twice' chuck.
