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.

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.

I usually just tap it gently with a piece of wood directly on the end of the bit. This will usually loosen it up. This also works with a router.

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

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

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

You will have to remove the plastic cap on the end of the tool where the tips go in. Then screw on the cutting guide.

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.)

Lowes, home depot and Sears sell them. Also, dremel.com sells parts.

Perhaps you are bending the shaft too much, or the original lube in the flex shaft has been compromised. Take it back to the dealer, for an exchange.
