“Always admired Dremel rotary tools. Waited until cordless available. It works like a charm. Allows precise drilling, shaping, smoothing without the bother of an electrical cord.”

Jerald M Savin, Amazon Customer Review

“I am very pleased. Haven’t touched my corded unit since it came. The premium cordless Dremel is much too large for small work. The small size of this unit is perfect. Dremel has become very cheap with their plastic case. Much worse than cases I have had before.”

MarxMack, Amazon Customer Review

“I have used this on several projects and it has worked well for everything. It has plenty of power and the battery has yet to run out on me during a project. Being cordless has been great for those jobs away from the house or tight places.”
