Benefits of a DA Sander
Let’s start by explaining why getting a DA sander is an excellent idea. First off, they work on practically any jobsite or work area. Whether it is a workshop, construction site, or even at home or office – they’re super versatile.
Secondly, DA sanders will sand almost any material. You can use them on concrete, paint, wood, metal, plastic, and all kinds of similar materials.
And thirdly, they’re super reliable and easy to use. You won’t have to worry about any danger when using one of these. And even if you don’t know how to use one – you can learn in just a few tries.
Buying Guide – How to Purchase the Best DA Sanders
You may find the perfect dual-action sander in the above list. But before you make a final choice, it is utterly recommended to know exactly what you’re going for. Here we explain the different factors to consider before doing so:
You will find two kinds of DA sanders: the electric-powered model and the pneumatic or air-powered sander. Both have their ups and downs.
For example, an electric-powered model has the chance to work freely without the connection of a hose or compressor. It delivers decent sanding performance, but it is not powerful enough for sanding metals or difficult surfaces. Luckily, they’re easy to handle and pretty convenient.
As for pneumatic models, you’ll find them usually more powerful and ideal for challenging tasks. The problem is that they’re harder to use, handle, and prepare. They’re most suitable for people with experience, as the learning curve tends to be steep with them.
The speed refers to how fast the sanding disc or pad moves. This will tell the user how much sanding you can get out of the machine. It is important to note that this speed is measured in RPM (revolutions per minute). Here, we recommend no less than 10,000 RPM if you want a decent experience.
Orbit or Disc Size
The size of the pad is another crucial factor to consider. It will tell you the area that the machine will sand around. The most common orbit size is about 6 inches. Most models come with this size because it is ideal for most operations, both small and large.
But you may also find small discs of about 4 and 5 inches or up to 8 inches for the largest ones.
Ease of Use
Something that adds extra practicality to DA sanders comes directly to how easy it can be to use. We usually recommend models that come with comfy handles and grips, as well as light designs of about 2 to 3 inches, and practical controls.
Other exciting features to consider that make a sander easier to use are vibration dampeners and well-positioned air exhausts. A dampener helps to prevent dangerous vibrations, which increases effectiveness. And a proper air exhaust prevents discomfort when handling.
Lastly, consider the durability of the piece. This comes directly from the construction. We can’t recommend metal builds enough. Especially if it is steel, that’s the best material to go for. But materials like aluminum or cast-iron are not bad either. They’re just not as durable or light to use.
Plastic bodies are not the best out there, but may also handle the job well enough. They won’t be as durable, though. Choose accordingly, and you’ll get a durable-enough sander for your needs.
