Finding the right polishing equipment is essential to maintaining your car's paint and luster. Apart from accuracy, power and performance are the other vital factors to consider when buying a speed polisher. In this article, we will highlight the DEWALT DWP849X review variable-speed polisher, which, according to the manufacturers, works wonders on metal and concrete surfaces.
DEWALT DWP849X Review
The DWP849X is the latest buffer from the US company and is arguably a much better version of the DWP849 polisher. For one, the DWP849X has a 12 Amp motor, compared to the DWP849, which had 8. You can choose between 7-inch and 9-inch models during purchase. However, there's no difference between the two models, except the size.
Some of the key features include:
1) Powerful 12 Amp Motor
The DWP849X comes equipped with a robust 12 Amp electric motor, which means you can use it in all the most demanding applications. More specifically, the motor can deliver up to 1,250 watts and RPM, ranging between 600 and 3,500 (depending on your requirements)
You can set your preferred wattage and RPM via the Controlled Finishing System, which works quite well in maintaining the set limits even under pressure. The CFS has a Soft Start, which keeps the powerful motor acceleration in check.
2) Wool Ingestion Shield
Dust, debris, and wool particles are inevitably produced during high-speed polishing at varying levels, depending on the surface being polished.
Accumulation of these particles in the motor can shorten its lifespan, and/or reduce its efficiency. The DWP849X comes with two cleanable Wool Ingestion Shields, to help protect the motor. They're cleanable too, which means they can last you for a long while if you're not a heavy user.
3) Ball Bearing Construction
The ball bearing construction effectively reduces the rotational friction in the motor and subsequently increases the durability of the buffer. This, in addition to the heat-treated, precision-cut gears, makes the DWP849X a very smooth, effective and durable buffing tool.
4) Hook-and-Loop Backing Pad
Included in the DWP849X's packaging is a hook-and-loop pad that enables you to seamlessly switch pads and accessories without much hassle. The disks are in a standard size and can go with different types of pads.
5) Multiple Handles
A good grip on a polisher allows you to control the application, enhance accuracy, and minimize mistakes. Whether you're buffing your sleek car's body or a concrete wall, you will certainly appreciate the DWP849X's multiple rubber-coated handles.
There is the normal side handle for secondary grip and a dynamic, 3-position bale handle for primary grip. Unfortunately, you can't switch bale handle's position without a tool.
As mentioned earlier, the DWP849X comes in two dimensions, with a slight 2-inch difference in depth. The overall width, including the side handle, is 18.5 inches, is slightly higher than average. However, the device only weighs 6.6 pounds, which makes it pretty easy to handle, even for someone with smaller hands.
How To Use The DEWALT DWP849X
Part of the DEWALT DWP849X's appeal is that it's so easy to use. To get started on the DWP849X, plug it directly into a wall socket, and switch it on. Then, scroll the Controlled Finishing System to set your desired RPM. Press the two-finger trigger system to get the motor roaring, and then hold the machine down on the surface you want to polish. When done with the polishing, first depress the trigger before you turn the device off.
Notably, the DWP849X makes quite a bit of noise, but that's to be expected, considering its power. You may, however, want to get some earbuds if you plan to use it for more than an hour.
The DWP849X is pretty straightforward when it comes to maintenance, as it has only a few parts that need regular cleaning and checkups. One of those is the soft rubber gear case cover, which can be removed by unscrewing the screws attaching it to the gearbox. It's pretty durable, so all you need to do is clean it regularly.
The polishing pads also need regular changing as working with worn out pads can undermine your work. To remove the pads, twist them in the anticlockwise direction, or the direction opposite the one used to screw them in place.
When it comes to the carbon motor brushes, DEWALT recommends inspecting them for damage or wear before using the machine. You can access the brushes by unscrewing the inspection caps holding them in place.
To enhance durability and seamlessly performance, the DWP849X should ideally be lubricated every month, depending on the usage. As a precaution, it's better to have the device re-lubricated at a credible service center, or if possible, a DEWALT service shop.
The DEWALT DWP849X is a very powerful electric tool and can easily cause damage if recklessly handled. To prevent body injuries, particularly electrical shock or damage to items, it is strongly recommended to disconnect the device from electric power before making any changes or adjustments. Wearing rubber gloves when handling the tool is also highly advisable.
For additional safety, only use accessories (backing pads, wool ingestion shields, etc.) that are made or recommended by DEWALT. You can find the recommended accessories on their website.
The DWP849X, with its power and sleek look, is one hell of a polisher. Its solid speed control system is particularly helpful on sensitive surfaces. The two handles allow for a good, strong grip, which boosts stability and minimizes user fatigue.
I also loved the 1-year free service guarantee that comes with the device, which is in addition to a 3-year limited warranty. Nonetheless, considering its the steep price, it's only fair that DEWALT gives these guarantees.
That said, it would be much better if the bale handle could be adjusted tool-free as the manual adjustment may be a disruption to professionals on tight timelines. Hopefully, this review helps you in making a good decision and if you do go on and purchase the DWP849X, don't hesitate to let us know about your experience!
