Dewalt DWE6423 review

The Dewalt DWE6423 orbital sander motor has a 3 amp motor and spins between 8,000 and 12,000 RPM. Counterweight design reduces machine vibration.

The equipment has an improved dustproof electric sander switch that prevents dust from being sucked in. Due to the fact that dust is not retained inside, it also lasts longer. The dust port works with this type of device.

The low height of the machine is by no means a disadvantage. It brings you closer to the device. You can easily see the machine and all activities. You can multitask with the one-handed dust bag of the dust collection system. Vacuum systems with 1-1/4 inch hose can be connected to the dust port.

This makes cleaning easy. Dust is not allowed in your workshop. Both the environment and your health will benefit from this.

When workers are around, they feel safe from sawdust-related respiratory illnesses. You will use the DWV9000 universal connector. Velcro fastened sand pad makes it easy to change sanding sheets. Maximum item weight is 3.52 lbs. The box contains one random variable speed DWE6423Orbital sanderand one dust bag.
