The air deflector protects the operator from exhaust and debris and the trigger lock-on button reduces user fatigue. Another factor in reducing fatigue is the extremely light weight of the sander; only 4.4 pounds.
The spindle lock makes changing accessories very fast and efficient. Holding onto the disc sander has a pistol grip and side handles that are covered with elastomer which is a soft material that makes it much more comfortable to hold onto rather than just hard plastic.

What Makes a Good Disc Sander?
There are many features that a high quality disk sander possesses that make it an excellent tool to add to your tool box. One of the first things to look for will be power. When the disk sander has plenty of power, even tough jobs are more manageable. Different sanders will have different power levels so think about the types of jobs you want the disk sander for when you are shopping.
Our pick has 6.2 amps of power with up to 4500 rpms, making it a great choice for moderate sanding jobs that require extended sanding time. Sanders can come in both cordless and corded varieties. Some people prefer one over the other, but what will deter mine which is the better for you is whether you want to worry about recharging batteries or if you need constant power being fed to the disk sander.
The grip a disk sander has is also important, especially if you will be using it on a regular basis. You want the sander to be comfortable to hold and use. Soft grips are very good for reducing vibration which can be a real bother and increase hand fatigue.
There are disk sanders that have palm grips, handle grips and some have a center grip and side handles too. One potential problem with palm grip sanders is that the handle will become hot during use and that can be very uncomfortable.
Variable speeds are always preferable so you can choose what speed you use to sand your projects with. Faster speeds are good for tough sanding and removal of rust and paint from your projects. Slower speeds are perfect for finer sanding and finishing work.
Trigger locks keep the sander locked in place in the on position so you do not have to continually hold down the trigger to keep it running. Having to hold the trigger down can cause cramping and tiredness in the fingers and hands and cause the sanding work to be uneven in spots.
