Hiomakone Bosch PSS 300 AE

The Bosch PSS 300 AE sanding machine is a compact random orbital sander designed for general sanding tasks on wood, painted surfaces and light finishing work. It features an idle oscillation rate from 14,000 to 24,000 OPM and a 1.8 mm oscillating orbit diameter that enables smooth material removal with reduced surface marking. The tool delivers 125 W of power while remaining lightweight at 1.8 kg and uses a rectangular sanding plate sized 115 x 230 mm to cover medium areas efficiently.

Advantages

The Bosch PSS 300 AE combines a high oscillation speed range with a small orbit diameter to provide a balance between aggressive stock removal and fine finishing. Its 115 x 230 mm sanding plate is suitable for reaching edges and flat surfaces, and the overall compact design supports comfortable handling during extended use. The moderate weight and power rating contribute to steady performance across a variety of sanding tasks.

How to use

Attach the correct grit sanding sheet to the 115 x 230 mm sanding plate according to the task. Start sanding with moderate pressure and keep the machine moving in even, overlapping passes to avoid creating deep marks. Use higher oscillation speed within the available range for faster material removal and lower speed for finer finishing. Allow the tool to reach operating speed before contacting the workpiece and lift it clear at the end of each pass to prevent edge gouging.

Recommendations

For best results, begin with coarser grits for stock removal and progressively move to finer grits for smoothing. Maintain steady, light pressure and replace sanding sheets when clogged. Use in well-ventilated areas and consider dust extraction or a vacuum connection to reduce airborne particles and improve sanding efficiency.
