Pros
Pro Great for surface finishing
This flat sheet sander is an excellent tool when you need to get a perfect surface finish on a flat workpiece. Due to the fast, low amplitude motion, this tool can remove even the tiniest bits of material, without damaging the surface, thus leaving a near-perfect result. When it comes to surface finish quality, this sanding technology is by far more superior than random orbit sanding.
Pro Perfect for corners
This palm sander can work on three perpendicular surfaces simultaneously, making it an ideal tool for sanding right angle corners.
Pro Large work area
While the majority of sheet sanders can work only with ¼ sheet sandpaper, this tool is twice as big and accepts ½ sheet sandpaper. Due to the low material removal speed, the increased working area is a huge advantage as it enables you to work faster.
Pro Feels sturdy and solid
As the body of this palm sander is made from sturdy, high-quality rubber, metal, and plastic, the tool does not feel cheap.
Pro Works with cheap sandpaper
The clamping mechanism of this palm sander is compatible with the regular sanding paper that you can buy at your local DIY store. You can use the provided punch-plate to make any sheet sanding paper suitable for this tool. This will significantly reduce your expenses as the regular sanding sheets are cheaper than the pre-punched sanding sheets.
Pro Vibrations are reduced
This palm sander has a dedicated suspension system, which isolates the handle from the parts that are prone to vibrating (just like a car's suspension damps the vibrations caused by road bumps).
Pro Comes with a dust bag
This palm sander comes with a portable dust container. Having an integrated paper filter, it will keep the level of dust in the air to a minimum. Contrarily to the simple paper bags offered by competitors, Bosch's container is made from high-quality plastic.
Pro Great for detail finishing
The low amplitude (2mm) eccentric motion, combined with the maximum speed of 12000 RPM, makes this palm sander a perfect tool for surface finishing.
Pro Versatile in light-duty applications
Due to the broad speed range (6000-12000 RPM), you can use the rough sanding pads to start the job and then achieve the perfect surface finish using your finest sanding pads.
Pro Perfect for corners
Due to the specific form of the pad, this palm sander is perfect for sanding right angle and sharp angle corners.
Pro Includes a handy dust bag
You won’t need to buy an external vacuum unit for this device as its 250 W motor is capable of extracting dust from the workpiece. However, if you do have an external vacuum unit, you can hook it up using the Festool’s 27mm adapter.
Cons
Con Suffers from dust and moisture
The body of this tool is made from multiple small elements. Thus the moisture and dust protection is significantly reduced. You will need to occasionally clean this palm sander to ensure its long and productive lifespan.
Con Not designed for heavy-duty applications
This palm sander is not powerful enough to be suitable for rapid and aggressive material removal applications. Random orbit sanders and full-rotational sanders perform much better in such applications.
Con Unusable for heavy-duty jobs
The small pad size and minimal material removing capabilities, make this palm sander unsuitable for any heavy-duty applications.
Con Expensive to run
It doesn’t accept the self-cut and self-punched sandpaper. You will have to buy the expensive Festool's abrasive sheets, which cost around $27.00 per a 50-sheet pack.
