Tools, Sharpening and Power Machinery - what lubricant do i need to use for a corded drill

hi,

i have a bosch corded drill. its quite old already but it still functions well both for masonry, wood and metal.

i only have one problem with it, after some time of storage, i notice that some type of fluid (quite viscous similar to grease) is seen in the casing of the drill. i am not sure if this is the lubricant spilling out.

when i try to run the drill, i can smell something like similar to a burning material (but NO smoke). and the drill body is warm to touch.

does this simply need lubrication? do i just have to open the drill and place some lubricant? what kind of lubricant do i have to use?

thanks,
leonard

I can only relate my experience. Most hand tools such as drills and saws have gear boxes. They do need to be regreased if used often but not greasing them usually will cause noise and not a smell.
You mentioned that some lube was leaking from the drill. Some of that may have gotten into the motor itself contaminating the brushes and armature.
Hand tools are a pain to get back together properly but it can be done. If you are knowledgable about motors and how to check them out then proceed to disassembly but if you arent it may be time to pitch it. Most hand power tools are not worth paying for repairs.
If you decide to dissemble. Make sure you unplug it. Corded tools use fatal voltages.:alarm:

besides the smell, i forgot to mention that i also hear some noise while the motor is turning.

fortunately, while observing the motor turning, i do not see any spark in the brushes (good sign though).

i'll keep things updated when i open up my drill.

however, i am still under the dilemma of what lubricant should i use.

Bosch has a grease for it's power tools but i think you would be safe using the white lithium lube.
