Ryobi 12v battery drill converted to pre-oiler.
Real oil pump rotors inside custom made housing on front of drill.
3 batteries and 120v charger included.
Made it for for my BDD/BDG Atlantic 15 years ago.
Used it for about 12 years - worked great.
Hours of use very small compared with normal drill use so should be fine for many more years.
$20 shipping to contig USA or Canada.
