Frequently Asked Questions
What’s the main difference between a drill and an impact driver?
A standard drill rotates to create holes and can drive screws, but an impact driver specializes in driving fasteners. Impact drivers deliver high rotational force in short, powerful bursts (impacts) when encountering resistance, making them far more effective for driving long or tough screws without stripping them, but less suitable for precise drilling.
Can I use a hammer drill for wood?
Yes, most hammer drills have a “drill-only” mode that disables the hammering action, allowing them to function as a standard rotary drill. However, for delicate woodworking tasks, a dedicated rotary drill might offer finer control and less bulk. Using the hammer function on wood will likely cause splintering and damage.
How do I choose between a corded and cordless drill?
Choose a corded drill for continuous, heavy-duty tasks where consistent power is needed and an outlet is available. They tend to be lighter without a battery and offer unlimited runtime. Opt for a cordless drill for maximum portability, convenience, and working in areas without power outlets. Consider battery voltage and amp-hours for power and runtime when choosing cordless.
