I've been hesitant about the earlier cordless Dremels but this one looks like "it".

So far it's done everything I've asked it to do but I haven't asked it to do much--I got it specifically to deal with a piece of acrylic that my cordless Rotozip melted instead of cutting--I figured the adjustable speed on the Dremel would take care of that and was right.

Just an aside about stalling--if you're stalling a Dremel then it's time to take a good hard look at a Rotozip, which, if you've never played with one, is kind of a Dremel on steroids--Dremel has an equivalent, the "Advantage", but only the one model and not cordless.

The lack of a provision to charge the battery with the tool attached is just carrying through the current practice with cordless tools--it's assumed that one will have two batteries, one on the tool and one on charge if this is an issue. There's space in the case for a second battery.

A "gotcha" to be aware of with the lithium ion batteries, always store them charged--if they self-discharge below a certain point a protective circuit kicks in and they disable themselves--this is a safety issue--trying to recharge a lithium ion battery that is discharged below a certain point can result in an explosion (I'm not talking about a little spill--exploding lithium batteries in emergency-locator transmitters have brought down light aircraft).

The bundled accessories are, near as I can figure it:

Aluminum oxide stone #932 and #8193
Silicon carbide stone #84922
Aluminum oxide abrasive wheel #541
2 rubber polishing wheels #425
3 Large felt polishing wheels #429
5 Small felt polishing wheels #414
1 cutter, looks like a #181
1 drill bit, #150
1 Mandrel #401 (for felt pads etc)
1 Mandrel #402 (for sanding disks, cutoff wheels etc)
Sanding cylinder mandrels 1/4" and 1/2"
4 80 grit 1/2" sanding cylinders
3 120 grit 1/2" sanding cylinders
4 80 grit 1/4" sanding cylinders
3 120 grit 1/4" sanding cylinders
11 sanding disks
17 cutoff wheels, 3 are thicker than the others, the others are in two containers of 10 and 4 but can't tell any difference between them.
1 wrench with screwdriver tip that fits screws on mandrels
1 case with a good deal of unused storage even after all the accessories are stored.

Dremel Lithium Ion Rotary Tool-Model 800 (Rating: 5.00)
Review : Finally, a cordless rotary tool that holds it charge while being stored. Now I don't have to worry about charging my tool's batteries the night before I need it for a project. And the Lithium Ion batteries are environmentally safe--unlike Nickel Cadmium batteries.
This tool is surprisingly smooth, yet seems as powerful as my old standby corded Dremel Model 395. At 35,000 RPM it is the fastest cordless rotary tool I've seen on the market. I like the sleek, ergonomic design. Based upon my previous experience with Dremel tools, I expect this tool to be trouble free for a long time.

I love this Dremel !!! (Rating: 5.00)
Review : Mine is utilized for robotics projects--it finds a lot of uses with metal. I also bought the press accessory with it. This little accessory helps me make straight cuts and drill holes.

I'm telling you, I use this thing constantly and it works like a champ! It is powerful enough for me to cut all my brass and aluminum with the precision of that of a doctor. For as handy as this tool is--I'd pay twice as much to get one if need be. I've had mine for 5 months too.

One HUGE word of advice. WEAR SAFETY GOGGLES! I know this may sound lame, but it saved my @ss!!! When cutting some tubing, my disk exploded at full RPM's and the shrapnel hit me in the goggles. (Of course I had my fat head over top of it while I was cutting) Just be careful. The tool is A+, but the little thing could be dangerous if you slack on the safety.

Lithium-Ion is SOO worth it! (Rating: 5.00)
Review : I've always wanted a dremel and thought that the cord would be fine. But now I'm glad I went with the cordless. I use it in the back yard, around the house, at work. Not only that, Lithium-Ion technology is outstanding. Blows doors off those old nickel rechargable batteries.

Lithium-Ion is the same technology being used in the most current cell phones. It doesn't have memory problems like the old rechargables so you can charge it at any time, YOU DON'T HAVE TO WEAR THE BATTER DOWN BEFORE YOU CHARGE! Also, the charging time is a fraction of what it used to be. If I run out, I put the battery on the charge for less then an hour and I have enough juice to finish the job. Typically, full recharging only takes 3 hours.

I highly recommend that you get this dremel (8000-01 10.8 Volt Lithium-Ion) if it is your first time, second dremel, or a dremel enthusiast.

Nice but underdesigned (Rating: 3.00)
Review : I bought one of these at a local brick & mortar store for a project I'm working on. I am impressed with the power of the device and it is a really neat tool, but unfortunatley I've already had to return two of them for a defective speed control. While using it, the first one all of a sudden just jumped up to full speed and stayed there regardless of where the speed control was set. In other words, it was no longer variable. The second one did the same thing. Since I saw replacement brushes available for their tools (and therefore they must consider it somewhat user serviceable) I decided to open it up and see what it looked like inside. One of the transistors on the circuit board had gotten warm enough to melt the solder and shorted out two of the pins on the transistor. I'm on my third one now (just returned them at the store) and I first bought one about 2-1/2 weeks ago. Great tool but Dremel needs to work on their quality control.
