An impromptu review of the 8000 Lithium Cordless Dremel.

When I first got my Dremel cordless (8000 Lithium Ion cordless Dremel), I was as happy as punch. I thought I hade been set free from the hassles of the electric cable forever (I have owned a Dremel MultiPro 240v for at least 15 years and it has never skipped a beat).

I use it for everything, cutting, grinding, sanding and trimming… the uses are almost almost as endless as the tools and accessories you can get for this device. 

Soon I owned the tile cutting tools, the routing table, the plunge router and the right angle devices all available at your local Bunnings store. 

Not far down the track, I found that the tool was not cutting as well as normal. About two and a half months in, the tool was no longer accurate or steady. At first I thought I had bent tools or that I had damaged the three jaw mini chuck – but soon I realised that the tool had actually started to loosen up on the sleave bearing at the end of the motor. Within the next few weeks my Dremel ended up with 1mm to 1.5mm slop at the tool end which made a mess of anything you tried to grind or cut... and this unit was no more than a few months old!dremel_tool.jpg

I decided to return the unit to Bunnings for replacement, thinking that based on my experience with my old MultiPro, the new unit must be faulty. Bunning organised to have it shipped to Bosch for what I believed was a replacement. 

Skip 4 weeks later and I started to wonder what was happening given I had not heard anything. I contacted Bunnings and they said they would follow it up. Two weeks later after many calls, I finally get a call from the Bunnings people to say that the Dremel has arrived in and has been repaired. “Repaired?” I said. And he proceeded to explain that initially Bosch had sent the tool back saying that there was nothing wrong with it. The Bunnings staff member checked the device himself against a new one and found that mine (in his words) “ran like a chainsaw” compared to a new device and promptly sent it back to Bosch. 

Bosch later returned the tool repaired, having replaced the motor, and included a notice saying that “I should be careful not to depress the spindle lock until the rotation has ceased”.

Back at the workshop, when I tested the Dremel, the tool still vibrated… not as bad, but it still vibrated. I could not believe it!

I decided to have a look at what was happening inside and upon undoing the body screws, I found that the two neck screws had been completely stripped out of the plastic. Upon closer inspection, because of the stipped screws the body would not clamp down and hold the head bearing securely. Thus the vibration.dremel_screw.jpg

I considered taking the unit back but realised that it was a waist of my time for a $149 item… and I had already wasted probably three hours on getting it repaired the first time round.

Although I have decided not to send it back, I did think it prudent to warn you all about not only the poor quality of the 8000 lithium ion cordless Dremel, but also the shocking service quality from Bosch Australia. The only bright light in this whole situation was the diligent Bunnings staff.

Moral of this story - Hang on to your old Dremel, or just buy the cost effective Ozito alternatives that are now readily available… they can be no worse than the cordless version !
