Morphology
The meaning 'a drill bit that has rollers' is directly and transparently derivable from combining 'roller' (a cylinder that rolls) with 'bit' (the cutting part of a drill). This straightforward noun–noun compounding follows common English (and cross‑linguistic) composition patterns, so a B1 learner who knows both words can readily infer the MWE's meaning.
Etymology
Roller bit is a drill head with hard metal rollers like small wheels that spin and crush rock as the bit turns. So, the name shows it is a 'drill bit' that uses rolling parts to cut through hard rock.
