I think it might be. I checked the brushes, which seemed ok. I removed the EZ Twist Nose cap to clean out any saw dust. I kinda messed around with the tool for a bit then I plugged it in and tried the power again . . . It worked! I began carving on my Tiger and after about 10 minutes the motor quit again. The Dremel didn’t feel especially warm and all of the vents were clear. I’ve had zero problems up until now. Hmm, I wonder . . .
I checked online and I found a few people who have experienced this same problem. I found this website with a pretty good review. According the reviewer the motor is the biggest problem with the Dremel. I’m still within the 2 year warranty so I better get to it. If you plan to purchase this tool I suggest you keep your receipt and packaging just in case.
Also, remember it’s not a commercial tool . . . so it requires frequent breaks while in use. Make sure you don’t put extra pressure on the Dremel while you’re using it. On some of the harder parts of the wood, I might have pressed harder instead of just allowing the tool to do the work.
Any Dremel 4000 owners know what’s up? Losing a tool is like losing a loved one . . . except you usually don’t have a warranty option.
