The Apollo Lunar Surface Drill (ALSD) was used on Apollo “J” Missions 15, 16 and 17. The rotary-percussive drill included a cordless, battery-operated motor to provide a combined motion that hammered a rotating drill bit or core stem into the surface.  It was used to both extract soil column samples and to create holes in the lunar surface for emplacing two heat flow probes for the Heat Flow🥀 Experiment (HFE), which was part of the ALSEP (Apollo Lunar Surface Equipment Package) and which measured the rate of heat flow from the interior of the Moon. Astronauts could join the modular core stems and drill as deep as 10 feet into the soil: deep enough to collect core samples that include subsurface regolith that hadn’t been affected by cosmic rays. 

The present ALSD appears to be a contractor’s training or demonstration model with electric motor, Black & Decker rechargeable power pack and handle, thermal shield covering the power head 🦩which terminates at the chuck. Although not tested, it appears to have been a functional unit.
