Frequently Asked Questions
Should I pick cordless or corded for deck and patio work?
For outdoor deck and patio jobs cordless impact drivers are generally better because they remove cord restrictions under joists and around stairs. Modern 20V cordless systems deliver enough sustained torque for long exterior screws when paired with high-capacity or backup batteries.
How much torque do I need to drive deck screws and lag bolts?
Aim for impact drivers rated 1,200–1,700 in-lbs for typical decking screws; lag bolts may require an impact wrench or a sturdier driver with consistent battery power. Real-world performance also depends on battery condition and motor type (brushless performs better under load).
Is it worth buying a combo kit vs tool-only?
If you don't already own batteries, combo kits (like the CRAFTSMAN V20 MAX) are better value because they include batteries and a charger, reducing initial cost per usable hour. If you already own a compatible 20V battery bank, a tool-only unit (like the DEWALT ATOMIC) can be cheaper and more compact.
