Overview
The DEWALT DCF900B is a 20 volt cordless impact tool weighing 6.4 pounds, sold as a bare tool under DeWalt's naming convention with the B suffix, meaning no battery or charger is included.
DeWalt's B-suffix model numbers consistently mean bare tool only, which keeps the price down for buyers already invested in the 20V MAX battery platform but means anyone starting from scratch needs to budget for a battery and charger separately.
- 20 volt platform
- 6.4 pound weight
- Bare tool, no battery
- DEWALT brand
Who it's for
Fits tradespeople and DIYers who already own 20V MAX DeWalt batteries and want to add an impact tool to that platform. Not a fit for a first-time buyer who needs a complete kit with battery and charger included.
Pros and cons
- Compatible with 20V MAX DeWalt batteries
- Bare tool keeps cost down for existing owners
- No battery or charger included
- 6.4 pounds is heavier than compact models
Performance notes
At 6.4 pounds, this impact tool carries more heft than DeWalt's lighter compact models, which can mean more sustained driving power but also more fatigue during overhead or extended work. Being a bare tool, its actual runtime depends entirely on whichever 20V MAX battery the buyer pairs it with.
