What type of drill is preferred for accessing spaces like attics in alarm system installations?

A flex drill is preferred for accessing spaces like attics in alarm system installations because it features a flexible shaft that allows the user to navigate around obstacles and reach tight or awkward spaces more easily. This flexibility is especially beneficial in attics, where height, limited visibility, and structural elements may hinder access.

Additionally, the lightweight design of a flex drill makes it easier to maneuver and control, which is crucial when working in confined areas. The compact size allows for portability and eases the strain during prolonged use, making it practical for the specific needs associated with alarm system installations in such challenging locations.
