Best Random Orbital Sander

For most construction works, you require sanding different surfaces. Maybe it is sanding your furniture or wood floor with a view of smoothening it you perhaps scrubbing off an old paint so that a wall can be painted afresh. Sanding can also be used with a view of roughening a surface. A random orbital sander is a tool that is held by hand. You can purchase one powered electrically, an air-powered one of the larger floor orbital sander, which is not hand-held. The 'random orbit' means that the sanding blade rotates in a random motion.

When this sand disk is spin simultaneously and randomly, unlike for other sanders, no marks will be left on the wood. Where two portions of wood need to be fastened at right angles, the random orbital sander works greatly since the sanding disk's random rotation is insensitive to the wood grain. These sanders have proven to have very significant advantages over other sanders.

Ultimate Buying Guide

When looking out for a random orbital sander, you must first consider the nature of the work you are carrying out. If your job is a regular sanding where a subtle finish is expected, go for a low power rated sander. More severe work will require a higher power rating like that of the Bosch 1250DEVS.

A dust collection system that is effective is also very key. You opt to look for a sander that removes most, if not all, dust on your working surface. This is to provide you a clean environment and neater finishes.

Handheld sanders require to be portable. Therefore, look for one that is light so that you can carry it comfortably within your site. Always get a sander that produces little vibration since too much noise can cause fatigue and poor results. Lastly, speed control systems are very critical. This is because you will have to vary the sander's speed several times to achieve the best finish.

Frequently Asked Questions 

Q: What Is The Best Random Orbital Sander?

A: This is entirely dependent on what your task entails, its needs, and expectations. A large floor random orbital sander will be suitable for contractors who undertake many and big construction projects. You will opt to go for a handheld sander that is smaller and lighter for your domestic use.

If your electricity connection is not reliable, you can go for a handheld sander that is air powered. You also have to consider the labor force to perform the task. Smaller and less complicated handheld sanders will be more suitable for someone sanding for the first time rather than giving him the complex floor sander.

The frequency of use of the sander is another major factor to consider. It will be illogical to buy a very large, complicated, and expensive floor sander with rollers for a one time project. This kind of machine would be suitable for construction contractors who use it regularly.

Q: How does an orbital sander differ from a normal sander?

A: The main difference is the oscillatory movement of the random orbital sander. The orbital sander, as the name suggests, moves in an orbit in a circular path. The random orbital sander, on the other hand, not only moves circularly, but the motion also has an oscillation. As a result of this back and forth movement, the sander can produce a neat smooth finish without swirls. The oscillation also moves on the working surface irrespective of the grain's slope, thus giving you a perfect finish.

Q: How Does A Random Orbital Sander Work?

A: As the name suggests 'orbital,' the sander has a circular motion. This circular motion, if alone, will result in a wood surface full of swirls. This is, however, avoided by the oscillatory movement of the sander. It moves back and forth in a random manner, which ensures any possible scratches are removed. The result is a neat, smooth, and uniform surface. Unlike other sanders that use square pads, this sander uses around the pad. This round pad is good because it does not get stuck into corners as easily as the square pad.

Final Verdict & Recommendation

The sanders we have seen above are all great tools for any woodworker. Each of the above sanders is suited to perform particular actions specifically. They all are tools of high quality and with great features such as the dust collection systems.

Suppose you aim at achieving the neatest and most uniform surface. I highly recommend that you purchase a Bosch ROS20VSC Palm Sander 2.5 amp corded speed sander. It has variable speeds of 7500 and 12000 OMP, which are relatively fast, making it very efficient.

However, as before stated, always first weigh your task's various needs, then with this in mind, choose the most suitable sander.

Last but not least, as for all tools and machines, safety precautions are essential. Always handle your sander with care, either when using it or storing it. There is still a possibility of physical injuries when mishandled.
