20 Most Recent Dremel Variable - Speed Multipro Rotary Tool 395 Questions & Answers

You'll need to use either the built in shaft lock to hold the collet in a fixed position, or use a pair of slip joint pliers to hold the shaft of the bit, while you use the wrench to loosen the collet. Slow and steady should get it loose. Another option is use some penetrating oil sprayed lightly onto the back of the collet to help loosen it from the shaft etc.

I have exactly the same unit a 395. The kit comes w/ a wrench to unscrew the nut holding whatever you have locked in. If you can't find the wrench then I suggest you get an adjustable wrench and lock it into the flat side of the nut. There is a place where it will lock in so that you can tighten or loosen the nut. Some of the 395's come as a kit w/ all the different attachments, accessories, heads and tools. If it came with a plastic case the wrench is usually slotted running parallel just in front of the handle. You will see it when you open the case and take a top view look at the handle. It is sometime hard to see but it's just there. Good luck.

Here's the email from I got from Dremel (in my case the flex coupling broke):
Inside the tool is a flex coupling and spline driver.

The flex coupling is # 2615294309 and the price is $ 1.25.
This is the hollow plastic sleeve about 1" long with grooves on the
inside, that goes between the motor shaft and the output shaft.

The spline driver is # 2615294308 at $ 1.00.
Spline driver sits on the direct end of the motor shaft. The flex
coupling sits over the spline driver. Spline driver is about 1/4",
hard plastic with grooves on the outside.

find the little square attachment and place on the end of the dremel tool. I didid the same thing. Worked fine after I put the other part on.

It doesn't attach anywhere, that's why it popped out. It should just fit in a recess, pushing the lock button outward.

the collet is either the wrong size for the shaft on the attachment or is missing alltogether

remove all the star head screws, unscrew the top plastic collet holding the plastic outer casing on. take a pair of vise grip locking pliers open the plastic casing just enough to expose the inner shaft inside the casing lock the vice grips onto the metal shaft between the bearing casing and the collet that is stuck enough to hold but not to dent it up. now that the vice grips are locked onto the main shaft get an adjustable wrench and size it to the collet screw size and turn it should come off rather easily or at least mine did just did it as i wrote this then screw the casing back together and happy dremeling hope this helps

unscrew the collet nut, and then if it's still stuck, tap the end of the bit on the table or something solid. It'll come loose then.

There is a collet stuck in there. It was probably in there without any tool in place, then the collet nut was tightened. With no tool filling the hole in the collet, it collapsed and became small enough to be pushed too far in. Fortunately these collets are soft steel. Find a sheet metal screw that you can screw into the hole. That will allow you to pull the collet out. Discard that collet. These collets come in at least two sized to accommodate different sizes of tool shafts. Unfortunately the spare one you have is one of those sizes, and the one you extracted is probably the other. But they don't cost much and you can buy them where you buy dremel tools. Good luck, Al K

Hello, M8052895 - I found a list of authorized Demel repair centers in the Philippines here: http://www.dremel.com.ph/ph/en/service/after-sales-service/dremel-authorised-service-centre-list/ If you scroll down that page, you will find a Philippines contact telephone number. Best wishes.

I agree with raysaw - sounds like a job for WD40.

Hi it sounds like you have a brush worn out. I would change out the brushes first and go from there. Brushes are relatively cheap and it is a good investment to check out first. You can get brushes from almost any hardware store that sells Dremel parts and accessories.

How stable is your line voltage? The SCR phase control used for speed control is more sensitive to line voltage changes at low speeds than at high speeds. Brushes should be changed when they are worn down to about 1/2 of their original length. Much more than this and they don't have enough tension to properly contact the commutator ring. Check with power off when the tool is cold and slowly turn the chuck by hand to feel the resistance. Run it a while and let the bearings warm up. Turn off power and turn by hand again. If it feels looser when warm (which would cause it to speed up at slow speeds), the tool might need to be disassembled and bearings oiled. I use Dexron automatic transmission fluid to lube most motors. Wipe down any excess.
