Rotary tool (Dremel) flex-shaft lubricant?
I just got a heavy duty rotary tool plus a flex-shaft.
Any suggestions on the best or easiest to find rotary tool (Dremel) flex- shaft lubricant? I noticed at first the spring rattled a little in the shaft, I guess (as they say) the lubricant has to spread around the area before providing enough slippage. They say to use little lubricant or the device will overheat. Thanks in advance. |

Rotary tool (Dremel) flex-shaft lubricant?
John Doe wrote: Any suggestions on the best or easiest to find rotary tool (Dremel) flex- shaft lubricant? ^^^^^^^^^^^^ This is not directly in response to your question, but I hope it saves you, or others, a lot of grief. I was using a Wecheer flex shaft carving attachment on my Dremel, when it started to make an odd noise. It was still working, and I wanted to get the job done, so I continued to use it, and the drive shaft broke. (It's made just like a Dremel flex shaft.) I pulled the broken end out, but there is no way to get the other half out. The shaft (and Dremel is the same), is closed at the business end. When the shaft breaks, the strands flare out and catch the housing, and there is no way to pull it out. Fortunately, the thing was under warranty, and I got a brand new one, but I started making phone calls, asking you are supposed to replace the broken drive core. Dremel just told me to send it in for repair. Wecheer told me nothing useful. My advice: inspect the drive core frequently, keep it lubricated, and always replace it if you even think it MIGHT break. Also, always keep the flex shaft as straight as possible when running it, and NEVER bend it to a tight radius when using it. Hope this helps. |

What sort of lubricant is suggested for these shafts. Presumable they require a fairly low viscosity due to their high speed. Thanks in advance for your help. John |

The flex shaft is a foredom. Maybe try a jewellry supply house. They sell flex shafts and could certainly tell you what they use. BTW, one nice thing you can buy is a fitting that clamps around the cable and housing and lets you force lube the whole length of the cable. Not sure if the ones they sell at motorcycle will fit your cable. Bring it in and see. Cheers, Eric R Snow |

What sort of lubricant is suggested for these shafts. Presumable they require a fairly low viscosity due to their high speed. Thanks in advance for your help. Dremel says: "The flex-shaft should be lubricated after every 25-30 hours of use. snip Wipe a very thin film automotive wheel bearing grease on to the center core and reinsert it back into the shaft. To prevent damage to tool do not over grease shaft. Too much grease will cause the unit to overheat". (They say too much grease can cause the hand grip to become very hot during normal use.) "Once Every 200 Hours ... The (Heavy duty Flex-Shaft Tool) cable should be thoroughly cleaned with a solvent and lubricated." I don't find any "thin film automotive wheel bearing grease". Apparently, they meant "a very thin film [of] automotive wheel bearing grease". |

I've seen it at hobby shops that sell Foredom tools, you can also get it directly from Foredom. It's a fairly stiff grease, too, no moly added. Hopefully, the shaft has a removable core, not like some I've seen that have been crimped together with no means of lubrication(Sears Crapsman). Stan |

Rotary tool (Dremel) flex-shaft lubricant?
I assumed that more folks used the same stuff I do. I had a buddy that
carved duck decoys using the foredom tools (he was pretty hard on them). He told me he used automotive anti-seize lubricant on them. When I got mine (Harbor Freight) I put anti-seize on it from the git-go. I've had it less that a year so I can't report on the long term. I also put a couple of drops of RemOil in the handpiece (don't know if that is good or bad). Bruce "John Doe" wrote in message ... I just got a heavy duty rotary tool plus a flex-shaft.
