Ranked in these QuestionsQuestion Ranking
It can be used effectively during all stages of a sanding project, due to having a good compromise between sanding power and surface finish. With it, you can relatively efficiently remove a large volume of material, and then reach an acceptable surface finish. For example, within 10 -15 minutes, this tool can sand an old 36" x 48" hardwood dining table to a surface finish level that's good enough to apply the first level of varnish.
Pro Multiple dust extraction options
This tool offers you two ways of extracting the dust from the workpiece.
First, you can use a vacuum unit, compatible with the tool's 27mm dust extraction port. While the vacuum units from Festool are very pricey (starting at $510), more affordable third-party vacuum units can be used.
Another option is to use a dust collection bag, which is provided with the tool. However, keep in mind that the manufacturer recommends using the bag only occasionally. For example, while working in tight spaces.
Pro Wide speed range lets you set any speed you need
You can adjust the speed of this palm sander according to the needs of your project. It ranges between 4000 and 10000 OPM (Orbits Per Minute). Slower speeds are great for sanding with rough sandpaper, while faster ones can result in better surface finishes when used with more delicate sanding pads.
Pro Decent build quality
The tool does not feel cheap or loose, as the body of this palm sander is made from high-quality rubber, metal, and plastic.
Pro The vibrations are barely noticeable
Festool palm sanders are well known for their state-of-art vibration damping systems. The manufacturer uses pre-calculated counterweights on the motor shaft to make this tool perfectly balanced for its 6" sanding disks. Build quality also factors into vibration damping, as this sander is made from large, cast plastic parts, which are less prone to vibrations. As a result, the tool vibrates so unnoticeably that you only need one hand to operate it.
Pro Keeps your hands dry and cool
The motor cooling system also blows air towards the hand grip. As a result, your palms will be dry and cool.
Pro Great handling
Due to an excellent geometry of the handle and lightweight design, this palm sander is perfect when it comes to working single-handedly. Additionally, as the handle is covered in rubber, the risk of accidental hand slipping is significantly reduced.
Con Worse surface finish than a sheet sander can offer
No matter how good and expensive a random orbit sander is, in terms of surface finish it will always lose to a lower quality sheet sander. If exceptional surface finish is something you are looking for, consider investing in a sheet sander instead.
Con Bad for corners
This palm sander is not suitable for sanding corners and edges due to its round sanding pad.
