Buyer’s Guide- How To Choose The Best Sander

To get the desired sanding results, you must check all required features before making the purchase. Buying an inappropriate tool will result in wastage of time and money. So, we will go through a knowledge base & few considerable features before you purchase any sanding machine. Let’s check out in details:

What is a Random Orbital Sander & Why it’s used?

A random orbital sander is a handheld tool in which an abrasive coated pad moves in a random orbit action for sanding tasks. Meaning, the sanding head, and disk have variable rotations.

Due to such movement, it does not leave any swirl mark and is insensitive to the direction of the wood grain. Some orbital sanders come with dust collection port wherein you can connect the dust bag, canister or an external vacuum.

Orbital sander use sandpapers disks that are attached using hook and loop system or pressure-sensitive adhesives. It is mainly used for stock removal and extra smooth sanding. It is also perfect to sand two wood pieces that are going to fastened at right angles.

Orbital Sander Vs Random Orbital Sander

The name sounds similar and they are also used for each other interchangeably, but there are significant differences between an orbital sander and a random sander.

  • Orbital sander’s head only moves in a rapid circular motion but orbital sanders oscillate as it spins creating fewer swirls.
  • You have to use orbital sanders in the direction of wood grains while the random ones have no concern for grain direction.
  • Orbital sanders are useful where you do not need heavy sanding or you just have to prepare a wooden surface for sealing or painting. On the other hand, random orbital sanders are used for decent stock removal and big jobs like refinishing wood materials or floor and even while sanding cabinets and shelves.

Things To Consider When Buying

Here are some of the points you need to consider when buying the best one.

Motor:Random orbit sander comes within a power range of 2 to 6 amp. Depending on the requirement, you can select the motor. If you are only involved in minor household tasks, then you can choose any sander that has a 2-amp motor. For household and some professional works, sander with a motor of 3 amp or more will be better.

Variable speed control: Most of the homeowners avoid the important feature of speed control. Variable speed gives you the facility to change the RPM for fine finishes and increase it for better stock removal. You can apparently get the same result by changing the grit, but why go the long way, if we have an alternate. So choose a tool that variable speed control.

Dust collection: ROS create lots of wood particles that may get into your respiratory system to create health troubles. It will also need you to clean the complete workshop time and again. Choosing a tool with dust bag may solve such issues. You should always look for a sander with dust bag or dust port that you can use with external debris collectors.

Power source. : There are two power options available to choose from – electrically powered or battery operated. While battery-based sanders are powerful enough nowadays but you cannot run it for more than 40 minutes on a single charge. On the other hand, electrical sanders are comparatively more powerful, but you need a nearby power outlet.

Disc or base plate size: A base plate is a disc where you can attach the sandpaper for sanding. Any sander less than 5-inch disc size is only meant for finishing. Anything above than that is considered for sanding.

The second thing to check the attaching system of sandpaper on the sanding disc. Most of the sanders on this list have a hook and loop system, which is reliable and is easy to use. Last, but not the last thing is to check on the base plate – holes. Holes on the sanding disc helps the dust canister to suck the wood debris. It keeps the working area clean.

Foam on the disc pad will need replacement after some time. Make sure that the sanding disc is replaceable so that you can easily replace the sanding disc instead of the complete sander.

Durability: If you are investing an amount on any machine, expect it to be with you for some years. Check its built and warranty. Look for a dust seal on the switch, ball bearings, and electronic housings.

Multi grips: Some sanders come with two grip handles while some of them have only one handle. Two handles give you better control but compromise the accessibility of the tool. One handle allows you to reach the right places, but you have less control over it. So, choose a sander that comes two handles, but one of them should be removable.

Differences: Random orbital sander vs Sheet sander vs Palm sander

Movement: Let us start with the sheet sander or an orbital sander. Orbital sanders are sold as sheet sanders as they accept standard 9×11-inch sandpaper. Two clamps on either side hold the sandpaper to the pad. Its head moves in a circular motion to sand any surface.

Movement of random orbital sander head differs as they oscillate as well move in orbits. As the pad vibrates and spins at the same time, you can use it for finishing as well as stock removal. Due to the random movement, it also leaves less or no swirls as compared to other counterparts.

Palm sanders are detail sanders that are used on sand small places, especially corners, edges and furniture with wooden designs on it. It can have any one of the orbital or random orbital movement.

Appearance: Most of the times you will find that a sheet or orbital sander has a square disc pad while random orbital sander (check UK’s top picks) has round and palm can come into two designs – circular or angular.

Weight: Both orbital sanders and ROS are lightweight, but the palm sanders are the lightest.

Working speed: Sheet sanders are not made for quick works as they remove layer after layer and will consume more sandpaper. On the other hand, ROS works comparatively faster and is good for heavy stock removal. A palm sander is also not built for heavy sanding or stock removal. It is ideal only for finishing and light smoothing.

Use: Sheet sanders are used only for wood sanding, rounding sharp edges, removing hardened wood putty and cleaning old paint coatings. You can use random orbital sander for smooth sanding, but it is also used for heavy stock removal.

Palm sanders are the smallest, as they are built for finishing. Sanding hidden corners, furniture joints, and tight places are the areas where palm sanders can perform better than any other sanding machine.

Orbital sander tips & tricks

Random orbit sander is one of the first tools that you want to have if there is any woodworking project around. It has all the features that you need for smooth sanding or finishing. But, you should know how to make the maximum benefits from the tool. So a little detail about the same will be good.

Safety: Before you start any woodwork, think about the safety first. Sawdust is created while sanding that is unhealthy, so always wear a face mask and glass while working.

Startup and shut down: Power on the sander and let it spin for a few seconds before making any contact with the material.  Once you are done, lift the ROS above the working surface before you switch it off.

Slow down: If you are habitual of using the best belt sander, then you will move ROS fast on the surface. But, that is not the right way as random orbital sanders are slow. You have to show some patient here and move it slowly to get the best finish.

Use the right sandpaper: On the sandpaper packets, you will see a number that is anywhere between 80 to 220. These are grits. Lower grits mean the sandpaper is coarse and will remove more material, but will leave the surface rough.

Higher grits mean, the sender will be able to remove fewer layers but results will be smooth. Always keep sandpapers of a variety of grits while sanding. So that you can get the look that you want from wooden materials.

Do not apply extra pressure: Applying extra force is not required while sanding any surface. The weight of the tool and your hand is more than enough to get the job done. Pressing the tool may put extra stress on the surface and machine that can damage any one of them or both.

Do not tilt: If you see any sold burn mark or stain on the wooden surface, do not try to angle the sander on that expecting fast removal. Random orbit sander are built to use on a plane surface always, so avoid any unusual movement. Pass the sander once again over the area that seems uncleaned or stained.

Bottom Line

We learned that ROS20VSC and DCW210B are the two best random orbital sanders that are not only powerful but are also comfortable and good in terms of dust collection. Apart from these two, we have included the best of the ROS that is both performers and money savers.

With this guide, you will not need to investigate much about the features that you need to check before buying a ROS. Look for the sander that suits your requirements, match the features and start working.
