For working teak you should get the corded Dremel 4000, it does have replaceable motor brushes.boutdone said:well said, that outlines exactly what I would like to do, well, after I recover from knee surgery. plans are to head out of Atlanta in the month of April 2020 to the southwest USA, now I know how to fill my hours. I was on the fence about getting a new Dremel tool to work on some teak I found on a shipwreck in the Caribbean many years ago. some woodworking is ahead for me again, that is a good thing. though I will do more of the alone stuff more than look for a socializing experience.
for a hardwood such as teak, or for materials such as bone, the rechargeable battery Dremel motors might well start smoking when doing longer stretches of carving time which will of course eventually lead to motor failure. Plus if they get overloaded in terms of torque they will shut off and you have to wait a while to restart them. They are very frustrating for anything other than light duty tasks, which I do like them for. Teak will be wearing out the burrs pretty quickly. There are better prices on those at https://widgetsupply.com/ and it is a good company to work with plus they have a very large selection of tools for use in rotary motors including very tiny sizes as well as larger ones. I also like their selection of diamond coated burrs in a wide variety of grits.
