Dremel Variable - Speed Multipro Rotary Tool 395 - Answered Questions & Fixed issues
Dremel 300 Series - I can't get a collet to go in
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.

Dremel rotary tool variable speed, low speed speeds up after short use. Will brush replacement solve this issue?
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.

Dremel multipro variable speed only starts in 4 or 5 speed
with tool unplugged rotate tool end with your finger tips if it gives any resistance to this your bearings have forign material in them (happens if your doing grinding allot) if a liberal dose of light oil (sewing machine) does not improve this friction im sorry but you;ll have to replace tool to run slower speeds

How to release dremel tip .already got screw it wont release
Press release button and hold down while unscrewing bolt. Continue to hold button and unscrew bolt until tip is loose enough to pull out if it still won't come out unscrew all the way, take bolt off and pull out tip with channel locks. It just got jammed in when tightening because diameter is probably a little wider

Dremel 395 won't turn on
I have a Dremel 395 Type 3. Motor works fine, shaft doesn't turn.
Took it apart to find that the white plastic or nylon flex coupling on
the shaft had crumbled and the spline driver, which fits directly over
the motor end of the shaft was somewhat worn. I emailed Dremel and got
an overnight reply listing the 2 parts I need and the cost: Coupling is
$1.00 and the driver is $1.25. Placed order by phone: 1-800-437-3635.
I ordered 2 of each in case future replacement is needed. Total bill
came to $7.27 including Florida tax and shipping. Can't beat that.
They said it would be in the mail by tonight. (Flex coupling number is
2615294309; spline driver is 2615294308.)

Have Dremel MOD 395 motor runs and speed control works bot shaft won't turn--worth fixing ??? and how
The tool that you require parts for was discontinued many years ago. Limited parts are available from Dremel.
Inside the tool is a flex coupling and spline driver.
The flex coupling is # 2615294309 and the price is about $ 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 for about $ 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.
Total shipping for orders under $ 5.00 is $ 2.50. Orders over $5.00 is $ 4.00. There could be a tax charge depending on which state you live in.
Here is how to order:
