❓ Frequently Asked Questions
What is FLEXVOLT Advantage?
When paired with a FLEXVOLT 60V battery, the drill draws more power for up to 77% more power than with a standard 20V battery.
Does it come with a battery?
The DCD999B is bare tool only. Look for DCD999T1 for a kit with FLEXVOLT battery.
Can it mix concrete?
With the side handle and low-speed setting, it can mix small batches. For large batches, a dedicated mud mixer is better.
