Why is my Dremel flex shaft getting hot?

Why is my Dremel flex shaft getting hot?

Flexshaft overheating (and eventual melting), is usually caused by incorrectly assembling flexshaft core when putting the machine together. If the flexshaft is assembled such that the steel core (the rotating part) is subjected to compressive forces then it will quickly overheat.

Can a Dremel overheat?

It does get hot when it is spinning at 5,000 to 35,000 RPMs. I was using it tonight for a few minutes & was surprised that at 10,000 – 15,000 RMPs that it was getting hot. Don’t block the vents. If the Dremel is overloaded, it will burn itself up & the accessories can burn out quickly as well if pushed.

Who in Dremel, did you speak to?

How odd….. a good friend of mine used to demo for Dremel at tools shows in the Tampa bay area. He is also one of the finest power carvers I’ve ever known. He always lubed the shaft and recommended it to me. But that was a few years ago. It could be that something has changed, I guess. Who in Dremel, did you speak to? Was it a service tech?

How much grease do you need for a flex shaft?

Purchased this for lubing the flex shafts for my WEN rotary tools and it works perfectly. It doesn’t take much lube so don’t stress over the size of the tube.; 1 oz will last a great while depending on how often/long you use your rotary tool. It’s grease, follow the direction for application.
