How To Pick The Best Orbital Sander
Sanding is one of the most tedious tasks in any construction work or DIY project. However, with the right set of tools such as an electric power sander, this task can be accomplished fast and effectively. The goal
An orbital finishing sander is also called a quarter-sheet sander due to the fact that it accepts a quarter of a sheet of the standard sandpaper. It has become one of the most common hand tools used in shops and homes because of its convenience and affordable price.
How Orbital Sanders Work
Orbital sanders require round disks of sandpaper, which are attached to the base of the unit using an adhesive or a hook-and-loop fastener. The motor of the orbital sander moves in a random motion. An offset drive bearing allows the pad to move following an elliptical pattern. The randomness of the movement prevents swirls from being left behind.
Benefits of Using Orbital Sanders
One of the major benefits of using orbital sanders is its superior capacity in removing any material. Because of its random motion patterns, it does not leave any swirls and thus results to a smooth finish. To achieve good results, changing grits is not necessitated, which translates to less hassle alongside the easily changeable hook-and-loop disks. Comfort is not an issue with this sander since it is lighter than other types of sanding tools. Thus, you will experience less strain and fatigue even when used for extended periods.
What Makes a Good Orbital Sander?
Each orbital sander has a combination of different features, which all play a part in making it an
- Power Source
Orbital sanders are commonly powered by electricity through a wired connection. However, some orbital sanders are powered through compressed air, for those used with a compressor in automotive and industrial settings. There are also cordless orbital sanders with batteries as power sources. These units feature unparalleled portability.
This is the part of the tool responsible for letting the energy from the power source flow though the orbital sander. Random orbital sanders either have a trigger or rocker switch. The latter is the common one present in light-duty units. For heavy-duty ones, the sliding trigger switch is used. This allows for improved safety in operating the orbital sander.
- Lock-on Button
This feature is only present in orbital sanders that have a trigger switch. This is located next to the trigger switch to provide easy tool lock-in operation. One thing to note about a lock-on feature is that it must be released before unplugging or disconnecting the tool from the power source to prevent automatic operation when the tool is reconnected.
Generally, orbital sander motors have a power of 200 to 750 watts. However, the more important is the output power delivered onto the sandpaper. This power is less than the input power because of the efficiency of the internal parts of the tool. Thus, when looking at an orbital sander, inspect the efficiency of its components to guarantee that more of its input power is delivered to the sandpaper. When comparing units against each other, it is best to look at the
This is the part influencing the speed of the orbital sander. The speed capacity of these tools range from 1600 rotations per minute to 26000 RPM. The bigger the value, the greater the capability of the sander is.
- Speed Control
This allows a preset of speed for the orbital sander. This enables the user to gain better control of the tool as varied applications require different speeds.
The housing protects all of the internal parts of the orbital sander. Since random orbital sander
- Sanding Plate
This is where the sanding disc is fitted either via a hook-and-loop system or a peel-and-stick Pressure Sensitive Adhesive. The former will need to be replaced when it is already worn out.
- Dust Collection System
All orbital sanders are connected to a dust bag or vacuum cleaner through a port. Light-duty sanding tasks that produce a manageable amount of dust can be adequately collected in a dust canister or bag. However, for bigger applications, the tool must be connected to a vacuum cleaner or a dust extractor. Dust collection is one of the most important parts of a sander since
What to Consider When Purchasing an Orbital Sander?
As you shop for an orbital sander, you have to assess which features are most important for you. These should then be included in the unit you plan to buy.
Aside from the features, you have to consider other important factors such as the diameter of the sanding disc, cost as well as availability of the disc, oscillating speed of the unit, frequency of use of the tool as well as the degree of its usage.
The combination of the power, weight, and versatility should be taken into account. Assessing the controllability of the tool can be done by inspecting the handles. The unit should have sizable handles placed in the best position for proper handling.
When looking at the hook-and-loop system, it is more convenient to have a finer one rather than a larger one. Fine hook-and-loop systems hold sanding discs securely as compared to the larger ones.
Finally, orbital sanders will be directed towards two different types of applications: DIY and commercial. Orbital sanders for DIY are designed for home use. They have numerous features with generous warranty offers. On the other hand, units for commercial use are built with reliability, durability, as well as performance as the top priorities. Its manufacturers offer shorter and limited warranties. In case of parts replacement, the parts are readily available in stores.
