Key Features of the Bosch Pex 220

The sander comes with a microfilter box. The built-in dust extraction traps the dust produced in the filter box. You are allowed to connect the sander to an external dust extraction feature such as the vacuum. The micro-filter system removes up to 80 per cent of the dust produced by the machine. The high-speed sander makes the collection faster. The box is easy to clean. You have a clean environment and clean air as you are working. 

Sanding sheets

The sanding sheets are easy to remove and replace. That is made quicker due to the Velcro-type fastening system that is convenient. Match the holes with the sandpaper, and a clicking sound when the hook and loop are attached. The sanding pad is 125mm in diameter. The sanding sheets are at the round base. The sanding discs have multiple types of grits that are ideal for different materials. The sanding plate is magnesium, and its large surface makes it an extensive surface material. 


The input power of the machine is 220Watts which brings high performance. The sander is five times faster than the standard sander. The machine is ideal for curves and polishing surfaces. The rotary and orbital movements give a scratch-free character. The powerful sanding machine also works on paintwork and other domestic uses. 

Palm grip

The soft palm grip makes the machine comfortable to handle. Sanding is easy and quick, using the handle. It is fatigue-free, meaning more time for using the sanding machine. The grip is rubberized, and that reduces vibration.

Key features of the Bosch Pex 300

Sanding sheet

The sanding sheets are easy and quick to remove and replace. When selecting a sanding sheet, there are factors to consider. The coarse sanding method sands down with high material removal. It takes care of old paint and varnish. Thin coats are removable. Intermediate sanding is for light sanding, face sanding, and working on irregularities. Lastly, fine sanding involves light sanding of coating defects. It removes fibers from surfaces and stains. That leaves the surface with extra polish. 

Dust extraction system

Your dust extraction system is effective. The punched holes on the sanding sheet must match the holes in the sanding plate. You are free to use the alignment aid. The Velcro has to face upward. You press the alignment aid into the two holes of the sanding plate. The sanding sheet has to be pressed firmly onto the sanding plate. The dust comes from materials such as lead, wood and metal material. It ensures good ventilation and prevents dust accumulation. It connects to a vacuum.


The On/Off switch works to start and stop the machine. It is a safety feature that prevents accidents when the sanding machine is not used. To activate it, you push the button, and it indicates 1. Stopping the sanding machine requires you to press it again, indicating a 0.

Orbital stroke rate

The thumbwheel is used for the preselection of the orbital stroke rate. You are allowed to preselect your preferred rate whilst the machine is running. The 1-2 is the low stroke rate, 3-4 medium, and 5-6 is the high stroke rate. What determines the stroke rate is the material. If you are not sure, practical tests are not forbidden. The machine has to cool down if you use it at a low stroke rate. You run it at the maximum with no load for about three minutes.
