What customers say about "Key Specs"
Dremel 8220-1/28 Cordless Rotary Tool
  • Separate power and variable speed switch. Variable from 5-30k.
  • EZ twist collet lock (no need to carry around wrench).
  • It has low level variable speeds which are very nice for especially slow and deliberate work.
  • I like this unit for the power/speed, which is fully adjustable via a slider switch.
  • I use this at work to grind dog's nails. I am able to set the speed where I need it and then turn the tool on/off at the separate switch. This is a huge time saver!
Dremel 4000-6/50 Variable Speed Rotary Tool
  • The Dremel tool itself is great and I really appreciate the variable speed settings.
  • It has plenty of power and the adjustable speed lets you tune the Dremel to the task at hand.
  • But this Dremel is powerful and has adjustable speed setting. It took me awhile shopping online and reading reviews to find a Dremel that would meet all my needs and this is definitely the one.
  • The tool doesn't have a lot of torque, so you need to let it operate at high speeds and let the rotational speed do the work.
  • I feel that it is worth the money to get your Dremel with a varible speed control. Speed does matter and it gives you something to play with when you get bored or just thinking things over.

What customers say about "Size & Weight"
Dremel 8220-1/28 Cordless Rotary Tool
  • Portable, enough power, light weight for hobbies and small fix it jobs.
  • Nice product, moderate weight in your hand.
  • Nice compact tool kit! Easy to handle and work with it.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • This unit works good. I previously had one of the original Dremels and finally had to replace it. They have made some real improvements. Nice size, weight and feel.
  • Not a commercial rotary tool but a light weight all around small task tool as in hobbyist tool.
  • It makes it hard to do some of the finer projects I was wanting to do because it's weight and size makes it awkward to handle.
  • The flex shaft is particually nice since it allows you to have a light weight tool in your hands for detail work.
  • I use this for my 2 Dremel work stations, drill press and router table, has the power the cordless doesn't, but the cordless is used more often for it's portability.

What customers say about "Features"
Dremel 8220-1/28 Cordless Rotary Tool
  • Takes all of the dremel attachments unlike some of the smaller models.
  • Handy case that stores the 8220 and many more accessories.
  • Quick release collar is new and great feature, no more wrench to chase down.
  • One of the best feature is that it fits all my Dremel accessories.
  • The only bad point is the carrying case: I wish the case were a bit more flexible in allowing more accessories to be stored with it.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • Comes with some nice attachments, can't wait to use the sharpener on my mower blades and see how well it works. Very pleased
  • This specific unit is extremely powerful, light, durable, and not too noisy. It includes a few bits which work well, but I wish i included more for the level of the kit.
  • The better tool ever for home or diy, probably doesn't works for heavy duty works. but so much accesories can be attached.
  • The tool is great the accesories are good but the only thing this that it did have the disk to cut wood that is my only fault with this product.
  • Great product; love that I finally have the full set with all possible attachments included in the package.

What customers say about "Power"
Dremel 8220-1/28 Cordless Rotary Tool
  • Plenty of torque and speed for grinding large dog nails. Don't waste your money on the cheaper lover voltage ones that bog down under the slightest load.
  • 12 volt separate battery and charger incase you want to have additional batteries. It is a quick charging battery taking about 1 hour.
  • Best feature is the removable battery. I can always have one on charge while I'm using it.
  • The battery holds a charge for a long time, and is fast charging.
  • I wonder if I got a dud for a battery. I can only do about 20 minutes on a medium speed before the battery dies. I am not impressed.
Dremel 4000-6/50 Variable Speed Rotary Tool
  • It feels solid in my hand and has good power for what it does.
  • As with all Dremel brand rotary tools, this is excellent construction, power, and versatility.
  • So I love the dremel (when it was working) great power, easy to use, simple, did everything I needed it to do, except power back up it just stopped working out of the blue and only used it a few times.
  • Be aware that you will lose some power with this extension, there were times when drilling and cutting that it would seize and I would have to turn it off, remove the tool, and start again moving slower.
  • It has plenty of power and the adjustable speed lets you tune the Dremel to the task at hand.
