Wow! how KEWL! a dremel with the Name "Micro" guess I'm gonna have to get a couple to replace my aging cordless Craftsmen 2-speed 4.8v cordless rotary tools. These new micros Look like exactly what I've been looking for....Thanks for the heads Up.
I'm still using a #260 corded dremel that belonged to my Mother from 1975. and have numerous other corded dremels hooked up to the various Dremel accessory tools: Drill Press, Router, Plunge Router, Router/shaper ect. More recently (Last 6 years) purchased a couple different fullsize Lith-ion Dremels that are REAL work horses. the Dremel 800a (10.8v) and 8200a. Yes they occasionally need to be recharged but if you carry and extra battery that is no problem at all.
Most of the corded Dremel tools work well in the house and I do still use them for lots of heavy work but have to say even in-house the Lith-ion battery dremels do all my finish and/or fine work.
As others have said the 4 collet set is a standard accessory and everyone should have a set or two. With these extra collets and/or keyless chucks any accessory up to 1/8" shank can be used. nor to the accessory tools need to be Dremel products. I buy 1/8" shank mill-end cutters from lots of drill and cutting tool distributors for use on every kind of material for balsa to Stainless Steel.
One work of warning about the keyless chucks: they do NOT always self center correctly. this is a Big problem when using very small or tiny drill bits and mill ends. I have a couple different keyless chucks direct from Dremel one works very well the other is almost useless for anything other then cut-off wheels or drum sanders as it just will not center correctly.
So rest assured just about any Dremel you come in contact with will be able to handle whatever tool or cutter you install
