User questions & answers

Question:	Do you use adhesive backed paper
Answer:	I don't know why not. We wear out at least two of these sanders a year in our shop and we use them to sand wood, plastic, aluminum, and steel daily, and sometimes other types of material as well. If you sand a car this sander would not be suitable for wet finish sanding as it is not sealed for that purpose.

User questions & answers

Question:	Does this sander come with connection capability for a dust collector system hose
Answer:	Yes, and no.... Check this out at Amazon: Bosch RS014 5" Buffing Pad I believe the sanders that this is listed as fitting are the same diameter hook-and-loop bases as the ROS20VSK just with a different mounting hole pattern of the base to the sander so it should fit, but the reviews of its performance are not great.Maybe there are other buffing pads that would work better.
Question:	I have a Porter Cable pancake compressor. However, would I need another type of hose and fittings, to connect the sander to the compressor, besides that which came with the compressor
Answer:	DAGS on "bosch ros20vsk 220 parts". Lots of responses. The first is ereplacementparts.com which carries it. There are also several others.
Question:	What size air compressor is required to run this sander effeciently
Answer:	I would say that a small amout of "cupping" is normal. As to 1/16 of an inch, I think that is a little much. Most of the sanding takes place on the outer edge of the disc. As it rotates the dust is sucked into the 8 holes in the center of the disc. In order to flatten out the disc, you would have to put more pressure than normal. My experience with this brand of random orbit sander is that the more pressure you put on the sander, the slower the disc turns. You need to have at least a moderate rate of rotation to keep putting new cutting surfaces forward and to get a decent "scrambling" of sanding marks.If your sander is older, you may want to purchase a new disc. They are relatively inexpensive. If the sander is newer you may want to see if the dealer or manufacturer will replace the disc.
Question:	Can the disk pad be replaced with the a velcro pad and where can I get it
Answer:	There is an adapter (part # VAC002) that will adapt the sander to standard vacuum hose sizes (1-1/4" & 1-1/2" hoses).

User questions & answers

Question:	Can i use this to sand drywall
Answer:	I think Amazon made a mistake. The pads I received a couple of years back, were about four inches in diameter and don't look like the ones shown in the latest photo. I'm not sure how they are attached, but as I recall, I used an attachment for my power drill that looked like a black rubber mat with an axel for insertion into the chuck of my power drill. The pads I received have a white cloth-like backing (about the texture of a flannel shirt). I think they are meant to be used with some kind of Velcro-like attachment arrangement. The trick is to keep them centered or they will wobble out of balance.
Question:	What are the minimum CFM’s required
Answer:	The adapter is not included with the pads
Question:	Can you wet sand a car with this
Answer:	The 5” is better, much easier to get centered
Question:	Will this air sander work efficiently with Dewalt 6 gal pancake compressor
Answer:	Unfortunately

• Professional High-Performance Dual-Action Random Orbit Pneumatic Air Palm Sander That Includes Two Different Styles of 6" Backing Plate Pads, One For Psa (Pre-Stuck Adhesive) Sanding Discs and One For Hook and Loop Sanding Discs.

User questions & answers

Question:	How do units like this vacuum the dust without holes in the pads? How good is it at sucking the dust? Thanks
Answer:	This is a throw size it measures 50x70 inches
Question:	Is this item a palm sander
Answer:	Mine are stored until winter, but they are lovely.
Question:	Does this come with a hook and loop pad as well
Answer:	Hi This is the black and white cow. The one that says Rodeo is the brown / dark brown cow print Thanks.
Question:	will a 17 gallon air compresor work with this sander
Answer:	I purchased the cow print and the two sides were not bonded together, only sewn along the edges. It was very noticeable after the first wash when one side shrunk and the other didn't. It was wonky looking after that.
