Higher speeds 5,000 35,000 rpm, same as Dremel corded models. High capacity 10.8V Lithium Ion battery pack for longer run times. Battery fuel gauge lets you know when its time to recharge. Variable speed to handle a greater range of applications.
Remember how cool we all thought that first Dremel was? We're reliving the feeling with this one: lighter, faster, smarter, better, and stronger.
The main improvement over the last generation is the battery source: lithium-ion. There are so many reasons to applaud. Lithium holds its charge up to six times longer in storage than nickel-cadmium batteries, so it's ready when you are.
Remember the disappointment when you were ready and your battery was low? That won't happen with this one. It's got a battery fuel gauge that tells you how much life is left before a recharge, so you won't be caught without your Dremel, and if you choose to keep it on its charger, you won't cause memory and shorten the charge capacity.
It's small, it's light, it's comfortable and maneuverable; it's everything the corded models are, but without the cord. We love it.--Kris Jensen-Van Heste, Amazon.com
