We have consumed 80 hours doing research and testing to have our top five straighline sanders, where we think that the Chicago Pneumatic CP7268 Heavy Duty Twin Piston Straight Line Sander is the best performing. From its dual piston power to the 3000 SMP and the ergonomic trigger and grip position, comes a tool that is capable providing the best results. It also helps that it has protective features as it goes quite fast with its SMP rate needing proper care from users.

During school break, I often visited my grandparents who have found love in making wooden chairs. Through the day they labored on creating this furniture from scratch.

One of the things they let me do is sand the smaller parts of the chair, which got be complaining at night.

When I was older, it was so frustrating to know about power sanders that could have saved me from the suffering.

Then I thought that my grandparents were in even more pain since they have to sand the more prominent portions of the furniture.

With them in mind, I set out to find the best sander to help my grandparents and you, who are in the search for suitable sanders.

We will center on the straightline sanders, which I think is the least common from other sanders, but as important as them.

Since it was hard to find, this review might help in reducing the time for research and even place them testing to determine if the right fit for different users.

How do straightline sanders work? 

Straighline (also “straight line”) sander is a type of sander tool. A sander is among the tools used in repairs and paintings. It helps prepare the material before painting or coating through removing the surface with the movement of the machine covered with an abrasive.

In this review, the focus is on the straight line sander. This sander type utilizes a back-and-forth motion instead of a turning one like the disc sander. It is most appropriate for creating straight lines and sanding on the edges of the wood or fiber or other materials

  • Heavy for some users

First on our review competes in the heavyweight tool that is followed closely by the Hutchins HUT2000 Hustler Straight Line Air Sander. It weighs 6.94 pounds, in which our testers found to be “as heavy as” the Ingersoll.

The weight is not necessarily a drawback as there are testers who think that the weight is just right. That is, your comfort on the weight of the tool depends on your strength when the tool is in use and vibrating.

3. Astro 888S Short Straight Line Sander (Second Runner-Up)

If the Hutchins HUT2000 Hustler Straight Line Air Sander is the heftiest, the third on our list is the lightest among all the tools. The Astro 888S Short Straight Line Sander has a weight of just four (4) pounds.

All the testers agree that the light weight makes the product less intimidating to use and provides more control over the tool. However, some of them have reservations if it can still perform with huge project or works.

When placing it into the test, the testers were amazed that the 4-pounds weight could run 3000 SMP like the heavier straightline sander. Thus, it can still produce a good finish on your subject.

Though this straightline sander as a good SMP speed, it is powered by a single piston. In contrast to the other products, the thrust power is slightly less stronger. There are also times when the testers found this straightline sander to be inconsistent.

On another aspect of the tool, our testers found that due to its shorter build, it is the effect when sanding hard to reach areas. It can even cater those are a bit narrow. Hence, it lives up to the expectation that a straightline sander is good for sanding the edges.

A drawback that our testers have found with the product is that it should be cleaned several times, so it does not halt while working. This is to take into account that the tool is smaller in comparison to others.

Like the other straightline sander, the trigger is at the bottom of the grip or holder. The positioning is comfortable for the holder to help in minimizing hand tension. The testers also like that it is easy to press for a faster job. 

What We Liked

  • Lightweight
  • Suited for narrow places
  • Comfortable grip

  • exclamation-triangle
    Requires more cleaning

The first opinion our testers have with the Ingersoll Rand 315G Edge Series Straight Line Air Sander is that it is heavy. In fact, it is heaviest in this bunch at seven (7) pounds.

Two of our testers deemed that this is for heavy industrial use rather than for home or personal use based on the weight alone. The testers, who were first timers and home DIY enthusiasts, find this tool heavy and difficult to operate because an extra force is needed.

Like the other products on review, this tool runs at 3000 SMP. Our expert testers said that the speed is fast enough to produce flawless output on the sample wood. Although the tool is on the heavy side with strong vibrations, the first time users see that it comparatively leaves smooth a smooth surface.

Our testers also find that trigger on the grip is easy to push at the heel of the palm helping the users work with it despite the weight. This ergonomic design also eased the vibrations when the tool is in use.

This straightline sander is packed with a double piston for reserve power. The testers said that this feature is useful in ensuring that the work does not halt and is powerful enough for large projects.

There are instances where the testers experienced halting during while doing the work. Our testers think that the jam might be because of the dust particles that have accumulated.

There are two implications of the jamming. First, it can cause inconsistency with the work and does not inspire confidence because the tool might break any time. Second, to remedy this, you need to regularly clean and remove the residue from the tool.

What We Liked

  • Efficient SMP speed
  • Dual piston for continuous work
  • Ergonomic handle

What We Didn't Like

  • Clogging material residue
  • Heavy

It has a similar double piston power that is adept at giving quality sanding results. This powers the 3000 SMP rate that adds to having a fast and impeccable finish.

The features that sets the Central Pneumatic Straight Line Air Sander from the other straightline sanders is its weight, and the coverage of the took when sanding.

Unlike the other heavy tools like the Ingersoll Rand 315G Edge Series Straight Line Air Sander and the Hutchins HUT2000 Hustler Straight Line Air Sander, this tool is comparatively lighters at 5.65 pounds. Even with its lightweight character it still provides the same benefits as the dual piston and the SMP rate of 3000.

Our testers believe that with such feature the Central Pneumatic Straight Line Air Sander can be valuable to help the users achieve more sanding tasks or large work.

An issue that our testers have observed is that there are times when the product is difficult to start-up. It may have something to do with product break-in as it will be used for the first time. But, during the testing after running for a few minutes, it stalled, and the testers could not figure out why. It, however, turned on again and continued to work until the testing was done. 

What We Liked

  • Bigger coverage
  • Power dual piston
  • 3000 SMP

What We Didn't Like

  • Seems faulty as it stops without apparent reason
