we used a handheld drill for several years.
The detailed description can be found in an older post on coral-list:

Maintenance: pretty simple: rinse in freshwater, run with air to dry the
tool, and apply oil generously inside the drill and on all moving parts.
The original paper is available on Research Gate:
