The DCE531B is DEWALT's 20V MAX cordless pencil concrete vibrator featuring a 1-1/8-in. vibrator head on a 4-ft flexible shaft that delivers 14,000 VPM under load. The isolated motor design reduces operator fatigue and improves durability in demanding concrete consolidation environments. Compatible with all DEWALT 20V MAX batteries and sold as a bare tool.
Does the DCE531B include a battery and charger?
No. The DCE531B is a bare tool. A 20V MAX battery and compatible charger are required and sold separately. Any DEWALT 20V MAX battery will work with this vibrator.
What is the vibration frequency of the DCE531B?
The DCE531B delivers 14,000 vibrations per minute (VPM) under load. This frequency is effective for consolidating concrete around rebar, eliminating voids, and reducing air pockets in slabs, walls, columns, and footings.
What is the head diameter and shaft length on the DCE531B?
The DCE531B uses a 1-1/8-in. diameter vibrator head on a 4-ft flexible shaft. The 4-ft shaft provides reach for deeper pours, and the 1-1/8-in. head is sized for residential and light commercial applications.
Why is an isolated motor design important on the DCE531B?
The isolated motor reduces vibration transmitted back to the operator's hands and arms, lowering fatigue during extended pours. It also helps protect the motor from damage caused by the high-frequency vibration of the head and shaft assembly.
Is the DCE531B suitable for residential and commercial concrete work?
Yes. The DCE531B is designed for both industrial and residential jobsites. Its compact cordless design is ideal for residential slabs, driveways, footings, and light commercial flat work where a corded vibrator or gas-powered unit would be inconvenient.
