Mini/Micro Slide Hammer
Mini /Micro Gear Puller
about 8 inches total length w/tip installed
Includes 3 assorted tips. Actual tip shapes might vary some from the photos
Tips have a metric thread of 4mm x .7 so that you can conceivably make your own tips out of a 1/4" metal rod. (if you are handy!)
Shaft is 7/32" diameter....the shaft and tips will fit through a 1/4" hole
This is small enough to fit into most small spaces.
Like most innovative tools, easily pays for itself in time saved and frustration avoided.
This seems to be the only one of its type on E-Bay
