Frequently Asked Questions

I have just built my cement wall and want to apply paint. Can I use this sander?

I must say it depends that how rough the wall is, and also depends on how you want the end results.

For instance, any wall that is too rough needs lower grit sandpapers.

I would recommend that you try the disc sander before applying the random-orbit sander.

With the random-orbit sander you may do final finish on your surface.

I am new to sanding, which speed should I use?

I recommend trying with the lowest speed since this tool has variable speed dial from 4500 to 12000 RPM.

So, start low until you find your way towards the highest speed that requires expertise in sanding.

You get the privilege to select the desired speed for each task treated.

Complex projects may require the minimum speed.

My pads are no longer effective, what can I do?

You can change pads easily by purchasing replacement pads either from your local store or online on Amazon.

Does this sander come with the vacuum for the removal of dust particles?


You have to purchase that separately.

Consider the Bosch VAC005 5-Meter Vacuum Hose 35mm from the same manufacturing company.

Any safety precautions to exercise?

Yes there are.

Precisely, you have to put on your protective apparels.

Consider the goggles, safety long sleeves, aprons and gloves.

There might be other dust particles towards you. So, you wouldn’t jeopardize your health with that.

Jerry's TakeJerry's Take
I bear testimony to the exceptional and remarkable industrial performance of this random-orbit sander.

My sister’s husband had bought one two years ago after they bought a new home, which they found the kitchen color quite unattractive.

So they had to remove the paint and this sander had come to their rescue.

They bought two and even now they are still functioning well.

The variable speed as well as the powerful motor built-in in this random-orbit sander is incredible.
