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 8100-N/21 8-Volt Max Cordless Rotary Tool

Variable speed so you can slowly work up speed without scaring your dog
This is a great tool. Has much the same heft and balance as the corded tool but without the hindrance of the cord. Plenty of power & speed.
Fantastic for dog nails...can't wait to play with other tools!! Battery holds a life for long tome! So glad I got the variable speed!!
Great for dogs of any size since the speeds are easily adjustable while working. So much better than my other 2 older Dremels.
I have a corded Dremel that is great for relatively heavy-duty rotary work, but needed a lighter cordless unit for quick lower-speed work.

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 8100-N/21 8-Volt Max Cordless Rotary Tool

Good size considering the power
The size of the tool is bigger than what I expected and am not liking that.
The small size of this unit is perfect.
Light weight and maneuverable. Easy to use.
However, the extra weight might take a little getting used to.

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 8100-N/21 8-Volt Max Cordless Rotary Tool

A case and plenty of bits included
Perfect! Ten different speeds and easy to use. Item is as described as well as the attachments it comes with.
I love this Dremel! Variable speed and the speed adjustment is in the perfect spot to easily adjust the speed with your thumb.
Bought it for keeping our dogs nails short and manicured. Works great! The variable speed option is great.
The adjustable speed settings of this Dremel do not work well at all.

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 8100-N/21 8-Volt Max Cordless Rotary Tool

Li Ion means no battery memory, longer life, shorter recharge times
This 8v unit is about the right power to do dogs nails , has a variable speed so you can start out slow to not scare them.
When I ordered this I was worried that it wouldn't have the power I needed, or the battery wouldn't last long enough. Both of those turned out to be untrue.
I highly recommend this unit to anyone who needs a quick and handy battery operated Dremel with some power.
