Random Orbit Sander Reviews
Our Top Pick is the Bosch Variable-Speed Sander
A random orbit sander is the perfect tool for stripping furniture, getting new molding ready for installation and other jobs where a strong sander is necessary.
The Bosch 3727DEVS is a great choice, equipped with a powerful 3.3 amp motor. The enhanced random orbit action ensures that you will have a clean, swirl-free finish with every project you tackle.
This sander uses the standard, 6 inch hook and loop disks that are super easy for anyone to change. It also has a dust canister that keeps dust under control and will keep your workshop, and your lungs free from dust.
This orbit sander has an opm (oscillations per minute) that ranges from 4500-12,000. The micro filter collects up to 120% more dust than regular dust bags. The medium hook and loop backing pad will corm to the surfaces you are sanding and lasts up to 5 times longer than the regular pads.
This sander also has exclusive dual bearing mounting system and the die-cast housing work together to reduce and virtually eliminate vibration and wobble which means a better finish and result. The Bosch random orbit sander provides aggressive removal of old paint and other materials to give you a clean finish in which to refinish.
The constant response circuitry feature maintains a constant motor speed even during tough jobs which provides overload protection and gives the person sanding a reduced torque soft start to prevent gouging. The variable speed dial allows you to decide how fast the sander sands, so you can adjust it to the specific job.
Since this orbit sander use standard 6 hole, 6” hook and loop disks, you won’t have to spend time or money for the much more expensive, proprietary abrasive disks. You also will never have to worry about troublesome adhesives.
The ergonomic handle has a comfortable soft grip top and the front and rear handles are also ergonomic for the ultimate in convenience and comfort. You won’t get tired with the multiple grip choices. You can even remove the front handle if necessary and you are sanding in tight spaces. The convenient trigger features a lock-on button that means you won’t have to just hold down the button constantly while you are sanding for long periods of time.
Dust can be a real problem for any type of sanding project. The Bosch micro-filter dust canister has an integrated paper filter that provides a great filtering system for fine dust. It can trap particles as small as ½ micron and reduces the person’s exposure by collecting far more dust than other random orbit sanders do. Weighing just 5.2 pounds, there is a 1 year warranty, 1 year service plan and 30 day money back guarantee.
Who Should Buy This?
A random orbit sander is a common and much valued tool with woodworkers, cabinet makers, furniture makers and professional carpenters. They are used to remove the finish from objects or to smooth a new project without the common swirl marks that other sanders leave so often. They are very easy to use and work on a variety of materials including wood of all kinds and sanding the edges off of plastics or laminate. Because of the clean, swirl-free surfaces the random orbit sander provides, it is a must have tool in any woodworker’s tool box.
What Makes a Good Random Orbit Sander?
There are several features that combine to make an excellent quality random orbit sander. One of the most important features of the orbital sander is how efficient and easy it is to change the sandpaper. Most sanders have a hook and loop method which makes changes very easy and fast so changing the sandpaper doesn’t slow you down.
A variable speed dial is another great feature in a high quality orbital sander. When you are able to control the speed of the sander you will have a smoother finish on your various projects because you can adjust the speed according to what you’re sanding.
If you are sanding something like veneer, a slow speed is much better and eliminates the problem of sand through. Overall, slower speeds will be better for a smooth, silky finish. A random orbital sander with a variable speed control may cost more but it is well worth the extra cost.
A good vacuum option is always a must in a random orbital sander. Most of the sanders on the market will come with a bag or canister to help with dust collection. This is important for health reasons in addition to keeping the workshop cleaner. The most effective method of getting rid of the most dust is to hook the orbital sander to a good quality shop vac. You will need to make sure that the connection on your sander matches the standard vac sizes of 1 ¼”, 1 ½”, and 2 ½”.
Ergonomic handles and grips are also important. The best sander in the world won’t be enjoyable to use if it is uncomfortable and hard to get a good grip with. You want to find one with multiple grip choices and that those grips are soft and comfortable. This will enable you to do long term sanding jobs comfortably as well.
For convenience look for an orbital sander that has a power cord with plenty of length. Having a short cord will force the person sanding to have to use extension cords. Having a long cord enables them to move around the object they are sanding without hindrance.
Some other features that are part of a great quality orbital sander include:
- Having a sealed switch to keep out dust and dirt
- Having it balanced and low vibration
- Trigger lock – on
- Portability (have a good carrying case)
- Tracking adjustment
