    dremel flex-shaft lube

    What's the proper, if any, way to lube a dremel flex shaft? Have seen online recommendations for Foredom flex-shaft lube, axle grease, lithium grease and nothing as in leave it alone. The first three saying be careful not to overdo it or the handpiece heats up. It's a basic dremel I've had for many years and is starting to get a little noisy. Probably needs brushes by now too.

    Cactus, not sure if this is right or wrong, but I use a very small amount of Moly-b on my fingers and lube the shaft with it. (ahem)
    Works fine on my flex shaft dremel adapter thingamajigger.

    I think I need to do this as well. Mine is making loud sounds, and heating up sometimes. I was thinking about just buying a new shaft since it is only $26 for a fresh one.

    I found these instructions on rio:
    https://www.riogrande.com/Content/Ho...x-shaft-HT-psd

    Steps
    1 NOTE: To ensure a long service life, we recommend greasing your flex shaft every 40 hours of use.
    BEFORE YOU BEGIN: Before performing any maintenance on your flex shaft, unplug the unit and remove the hand piece.

    2 Lay both the motor and shaft on a flat surface. Using a flat-head screwdriver, loosen the set-screw on the motor housing, just above the shaft.

    3 Slide the sheath down and remove it completely, exposing the inner shaft. Using a rag or shop towel, wipe the inner shaft to remove any existing, old grease.

    4 Squeeze a small bead of grease (about 1/16" dia.) from the tube, then starting at the top of the shaft (closest to the motor) run the grease along the length of the shaft, stopping approximately 6" from the key end of the shaft.

    5 Place the sheath back on to the shaft, then slide the sheath up all the way to the motor connector.

    6 Adjust the placement of the shaft so that 3/4" of the shaft end is exposed at the end of the sheath. If too much of the shaft is exposed, the handpiece will overheat and wear prematurely. However, if the shaft doesn't extend far enough, the shaft itself could also overheat and suffer damage.
    Once you have the sheath placement correct, tighten the set-screw to secure the sheath in place.

    7 Hook the motor back onto the hanger and plug it in.
    IMPORTANT: Do not attach the handpiece before hanging up and plugging in the motor.

    8 Place a trash can under the shaft to catch any excess grease.
    Run the motor at high speed for 10-15 minutes. Running the motor heats up the grease, allowing it to redistribute down and throughout the shaft (the excess grease will drip out of the end of the shaft and into the trash can. It's important to allow that excess grease to drip off, other wise the grease left in the handpiece may cause the handpiece to overheat.
    Re-attach the handpiece for use.
    REMEMBER: Perform this maintenance task about every 40 hours of use.

    Who knew greasing "the shaft" could be so laborious? LMAO!

    Yeah, it does kind of read like a porno script. I've seen similar instructions from Foredom but those hanging tools are heavier and higher torque than my old dremel so wasn't sure. The Rio Grande site doesn't mention what kind of grease. I may call dremel next week and get it from the horse's mouth. Thanks for all the input so far.

    Couldn't find the definitive answer to dremel flex shaft lube so kept digging around and lo and behold found my 20 year old manual. So for anyone interested this is what it says for my model 395 Type 5.

    "FLEXIBLE SHAFT LUBRICATION - The flexible shaft should be lubricated every 25-30 hours of use. To lubricate, unscrew the flexible shaft assembly from the motor housing. Pull the center core out of the flexible shaft assembly. Wipe a very thin film of a good quality, high temperature grease on to the center core. To prevent damage to tool do not over grease shaft. Too much grease will cause the unit to overheat. Dremel shaft lubricant No. 5990952 or automotive wheel bearing grease should be used. Reattach flex-shaft to the rotary tool."
