What Makes DeWalt DWP849 Standout?

Powerful 12.0 AMP Motor

The first thing a polisher or any rotary tool should have is a powerful, smooth motor. Some tools claim to have a powerful motor, but the motor doesn’t run smoothly or cleanly in reality. We have deconstructed the device and found out how beautifully the motor is placed into the tool. When you turn on this polisher, the tool will give you a superior and powerful speed to work.

Ball-Bearing Construction

Ball-bearing construction is one of our favorite types; it helps the tool in preventing internal damage. Now, inner section damage and motor damages can happen for many reasons; with the ball bearing mechanism, the chances of the motor being damaged are meager.

Electronic Control

We have worked with it for hours and switched too many speeds according to our preferences and found the load under control. We noticed that the electric control mechanism featured in this tool helps to keep everything under load. So, when working with this orbital sander, you don’t have to worry about extreme overload or anything like that.

Conveniently Located Variable Speed Dial

We have purchased six different polishers that offer the same features and the same price point, but the switches were not placed comfortably inside the tool when we were working with them. When the buttons and triggers are in a place that is hard to reach, it becomes a pain while driving. Variable speed dial and trigger are placed so conveniently in this device, it’s just incredible. The switches are not too hard to feel, and the dial is easy to change but won’t change the speed if you touch that gently.

If you’re wondering about the speed quality, the device will deliver the exact speed you want, and the electric module will keep the momentum under control.

External Brush Cap

The tool features an external brush cap to hold the brush in place. The brush will be tightly in place and give you a better finish.

The Large Spindle Lock Button
