Random Orbital Buying Guide
Random orbital sanders produce an aggressive sanding motion that can sand away a lot of your workpiece if you’re not careful. That’s why it’s important to choose a tool with a variable speed setting. The general rule is the wider the range of speed, the better as this gives you more control when it comes to sanding.
Cordless or Corded?
If you’re working indoors and you have ready access to an electrical outlet, then it is best to go for a corded random orbital sander.
A portable cordless sander is the better choice if you’re going to work outside or your job site doesn’t have access to an electrical outlet. Sanders like these are powered by rechargeable lithium-ion batteries.
Although they have the advantage of being portable, you have to make sure that you’re not going to use the tool for several hours as their run time is limited.
The Right Type of Handle
Most random orbit sanders have a palm grip design. This allows you to grasp the top handle located directly on top of the pad and fully control the direction of the tool.
This design, on the whole, is ergonomic and keeps hand fatigue at a minimum. The problem is that some models have a bigger palm grip compared to others, making them difficult to grasp for people with smaller hands.
Palm sanders are ideal for smaller projects thanks to their compact and lightweight bodies. Apart from the palm grip, you can also hold them around the neck for greater control.
If you want greater control and a more secure grip, then check out random orbital sanders with D-handles. Some models even have the trigger switch located right below the handle for a more convenient operation.
If you want to reduce hand and arm fatigue while maintaining a firm grip on your tool, then check if the model has an auxiliary handle. A random orbital sander with an auxiliary handle is more convenient, and you can be assured that you can apply just the right amount of pressure to the tool while working.
It is also easier to use the tool vertically or overhead when it has an auxiliary handle. Some units have built-in auxiliary handles, while others have auxiliary handles that can be adjusted and removed when necessary.
Choose a 6-inch random orbital sander if you want to take on larger projects as it covers more area. But if you’re a hobbyist who tackles smaller projects or you want something lighter and budget-friendly, then go for 5-inch random orbital sanders.
