Random Orbital Sander Vs. Sheet Sander Which Is Right For Your Job?
We Will Go Over How, Why, And When To Use Each Of The Two Most Common Types Of Power Sanders: Random Orbital (RO), And Sheet (Finish) Sanders.
Sheets Sanders Overview Sheet sanders are best used for the final preparation step before applying paint, finish, lacquer, stain, or whatever else.
Also called palm sanders or ¼ sheet pad sanders, they typically use ¼ of a standard 9 x 11” sheet of sandpaper.
They have a square sanding pad, and most models use some sort of spring-loaded clamp device to hold the sandpaper in place on the pad.
Sheet sanders move in a simple back and forth motion, which is nice if you’re not wanting to sand through a lot of material at a time.
Sheet Sander Pros
Sandpaper is widely available and inexpensive
Best option for finish work
Great for 90-degree angles
Affordable
Sheet Sander Cons
Less powerful (can’t take off a lot of material)
Not a wide range of use
Prone to leaving swirl marks
Random Orbital Sanders
Random orbital sanders are a better option if you need to take off layers and layers of rough material.
RO sanders can be controlled and manipulated much more by the user than sheet sanders can.
Random orbital sanders use circular pieces of sandpaper that attach to a sanding disc (usually with velcro).
Random Orbital Sander Pros
Powerful,
Wide range of use;
Better dust collection
Rarely leaves noticeable swirl marks
Random Orbital Sander Cons
More expensive
Can’t reach tight corners / 90-degree angles
Best Sheet Sanders
Makita BO3710 ⅓ sheet sander
This is a bit expensive for a sheet sander, but it’s a seriously quality tool with a great clamping mechanism, a very solid aluminum sanding plate, and a great dust filtration bag that actually works.
DEWALT Electric Sander, 1/4-Inch Sheet, Orbital (DWE6411)
Like the Makita, another no-frills, super-quality tool that has just a little more punch than your average sheet sander, with its 230W motor that operates at 14,000 orbits per minute.
SKIL Precision Control ¼ sheet palm sander with Microfiltration
The dust capture with the Microfiltration system is second-to-none, and the Precision Control system uses lights to let you know when you’re applying the perfect amount of pressure - when you’re in the ‘green zone’, you’re sanding at maximum efficiency.
Best Random Orbit Sanders:
DeWalt DWE6423K 5-inch variable speed random orbital sander
This 5-inch variable speed RO sander is the our favorite, hands-down. It’s not absurdly priced, and it’ll do as good a job or better as models with a much larger price tag.
SKIL 7492-02 5-inch random orbital sander w/ Precision Control
We’ve heard a lot of people say these SKIL sanders with the Microfiltration and Precision Control are just gimmicks, but with a price about half that of the DeWalt, we say it’s a heck of a value buy for a good, functioning sander.
