Cordless Handheld Concrete Vibrator Kit. A flexible vibrating shaft, and two rechargeable batteries inside a black carrying case. This tool generates between 4,200 to 12,000 vibrations per minute (VPM). The high-frequency vibration pushes trapped air pockets and excess water out of fresh concrete, filling voids to prevent structural honeycombing.
Type: Battery-powered poker concrete vibrator used to remove air bubbles from wet concrete.
Power Source: Rechargeable lithium-ion battery pack (marked 288V nominal/store rating).
Accessories: Two batteries, a charger, and the vibrating shaft/poker attachment.
