Desc. says it has a Quick Change Head, is this the locking type where you slide a collar to load/release a bit, or the magnetic type non-lock type?

If you look at the pic of the driver, the black collar slides fwd and back to lock the bit in. Additionally it comes with a bit that locks into the driver, that just has a magnetic tip to hold regular bits that don't have the little indentation.... So I think I boil it down for you by saying....... yes it locks bits that have the indentation/ground down spot on them and if it's s smooth quarter inch hex bit it doesn't lock them. Hope this helps..

Yes, it has the 1/4" quick change bit holder. If you want the 3/8" chuck, you will need to look at the other model #.

The blue collar is part of the bottom piece. Mine only twists half a turn to loosen or tighten. I haven't had any problems.

I can not say that it is, or is not, a magnetic switch. I can tell you that it performs the same function for me. I use these on my woodshop tools. I have tested them by turning on a tool, then turning the circuit off to simulate a power outage. When the breaker is switched back on, the tools do not re-start. You must physically turn the tool back on. Great, and necessary safety feature.

Has hook in back of where the lock would go into the void . Not a circular lock. Has a collar. Can lock by quarter turn or half turn to lock and unlock the straight down side bar. Looks like the one I just bought from you.

No, it is not magnetic. However, there are spring-like "grabbers" down in the chuck that hold the bits in place very securely...they do not fall out.

DWARA100 had a magnetic piece that surrounds the bit and can slide out to make contact with the fastener head, keeping the fastener on the bit tip. The magnetic piece is attached to the black plastic visible near the inside of the right angle of the tool. DWARA50 does not have this magnetic piece. Also, the magnetic piece doesn't quite reach the fastener head for #8 or smaller screws.

Both are 1/4" hex quick change type, or words to that effect. The chuck on the unit without the clutch or dual-speed switch appears "beefier" although the bits fit looser in terms of in-out play.

correct-a 3-position collar selects low-speed rotary drilling, high-speed rotary drilling, or hammer drilling.

My unit does not have a lock on switch - Amazon must have information that is old or simply in error. But I honestly can not imagine you would want one, since this is a variable speed grinding tool. I was grinding off hardened 1/2" threaded bolts - it did that job easily at full speed.

My drill, which is Model HD21-2, does not have a lock button nor does it have a variable speed control on the trigger as shown in the photo in Amazon. Although a lock button may have been useful, I can see no value in a variable speed control in a drill with a 2 speed gear change.

A collar is necessary, pull the collar back and insert the bit, The bit should lock right in place.

Amazon has a variety of magnetic bit holders. I suggest a 1.5 or 2 inch length for general use. The Hitachi is an excellent too that comes with a bit, but not a magnetic holder.

quick refers to the ability to change the grinding wheel quick, not the speed of the rotation. It is a very convenient feature which allows you to change the wheel with no tools. you simply turn the tool off, and when it has run down to about 30% speed you push the spindle lock button and it loosens the nut to finger tight.

Make sure you're trying to turn the collar only... its right hand thread so turn counter clockwise as you're looking at the tip head on... try wrapping a rag around the collar and use a channel lock style pliers

It mounts with a knob tightened by hand on the opposite side from the picture so I would say yes it does have a quick release

It is a NO switch. It is closed when the magnet is holding it closed, called a "closed loop" and opens when the magnet is removed (normally open)

It's easy to move it to the position you want, then lock it in. The supplied Allen (hex) wrench does the trick for loosening/tightening all swivel points.
