I picked up a Keller Tool Co rotary tool no. 1033. It has a 1/8" pipe thread opening not 1/4 as every other air tool . It is also described { if I search the patent number 2099280] as a hydraulic tool . This makes no sense because it must be pnuematic as it only has one opening . [ I mean what would it do spew spent hydraulic oil out some port?]. It also has a quick release chuck that takes 1/4" hex shaped shafts. Searching the patent makes me realize it is pnuematic but why would it be called hydraulic ? Anyone seen an air tool inlet in 1/8 pipe thread? Also has a grease fitting near the air entrance. Grand Haven Mich. Lots of other writing too.
