A rotary hammer will absolutely demolish this job compared to a regular drill, and it's worth the investment if you're doing more than just a couple of holes 🔨 Regular drills can technically work with masonry bits, but they're slow, wear out your battery fast, and you risk burning out the motor since they're not designed for the repetitive impact that concrete needs. Rotary hammers use a pneumatic or electromagnetic hammering mechanism that does most of the work for you - it's like the difference between chiseling by hand vs. using a jackhammer. For basement shelving, you'll drill faster, cleaner, and with way less frustration, plus the tool will last longer without getting cooked.
