Cordless Drills

Voltage, brushless motors, chuck size, and which drill you actually need.

The cordless drill market splits into three voltage tiers and two motor types — and most buyers overspend or underbuy because they don't know which variables actually matter for their work. This page covers voltage, brushed vs brushless, chuck size, and when to choose a hammer drill over a plain driver.

Guides

Real buying-guide content — voltage math, motor comparisons, and what specs to ignore. No brand padding.

Troubleshooting Why your cordless drill won't turn on or won't hold a charge — it's the battery pack, not a dead drill Dead in your hand, or a charger that blinks and refuses the battery? It's almost never the drill — it's the pack, and often the pack's own brain protecting a cold, hot, or flat cell. The symptom-by-symptom fix before you spend $120 on a new kit. Buying guide How to choose a cordless drill: 12V vs 18/20V, brushed vs brushless, and chuck size The voltage rating, motor type, and chuck size that match your actual use — from light assembly work to concrete anchor drilling. Common mistakes buyers make and how to avoid them.

Why this page exists

Cordless drill content online is almost entirely sponsored comparison lists. Brands pay for placement and the specs that matter most — motor efficiency, no-load vs under-load torque, battery platform lock-in — get buried under affiliate rankings. Neither tells you the difference between a 12V and an 18V in real-world drilling.

A brushless 18V drill and a brushed 20V drill from different brands may or may not have similar real-world performance — because peak voltage numbers don't tell the whole story. This page explains what does.
