ROS sandpaper come in 5, 6 and 8 hole styles. Does it really matter which style of sandpaper is used on any ROS? Dust pickup on most ROS’s is pretty poor unless a vacuum attachment is used.

I use a vacuum on mine all the time and try to match the holes. It still only works fair. I have a DeWalt and a Bosch; the B is a smoother operating sander by far. Dust pickup seems about the same from both.

I always hook a dust collector up to it. Gotta save our lungs from that fine dust. Especially the fine stuff from a ROS

Yes it matters a lot. More so which sander you get, The bosch ROS20VSC has amazing dust collection and actually leaves my work pieces squeaky clean. I bought the hose to run DC directly to it an i quickly learned it is not needed. The pleated filter does a fantastic job of keeping the dust contained.

The Bosch that Mike does a great job of collecting dust. The same goes for the Makita BO5041K. They work as well as my old PC with the dust collector hose attached. I use Mirka Abranet disks, so that might help with the dust pickup.

What about this stuff from DeWALT?

Looks like you don’t need to worry about lining up the holes and it clogs less.

I use a vac and match the holes and I think it does a good job, so yes, it my experience it matters if you use a vac, not if you do not.

This is what I’ve been using. Can’t say enough good things about it. It’s more expensive, but lasts way longer and there’s virtually no dust that can be seen. I’m sure there are small airborne particles, but that’s what respirators are for :)

Mirka Mesh

Edit: It also doesn’t clog.

Hooks and loops…. I learned the hard way.

The hooks on the sanding pad are tiny plastic hooks. If you have a 5 hole sander and put 8 hole paper on it the hooks poking through will be sanded off. Sometimes when the sandpaper flies off (after the hooks are worn enough) the rest of the hooks get sanded smooth.

Mirka paper…. or any other that’s mesh. It’s really great stuff. lasts a long time… but the hooks on my Bosch were worn smooth after several uses of it. I love it but don’t use it any longer. And…. even though my Bosch had decent dust collection with a hose and vacuum, many sanders don’t, I’m now using a pneumatic sander (hook and loop) with no holes. My hooks don’t get worn off as no holes to line up.

Another tip: Don’t press down. It creates heat and melts the hooks enough so they are soft and get destroyed.

They sell interface pads that protect your sander hooks. It’s nothing more than a perforated pad with hooks on one side, and loops on the other. You stick it to your sander, and then attach the disks to it. Where it excels, is that you attach and detach the sanding disk from it, not your sander base, so there’s less wear on it.

Ya, I bought one and that wore out after awhile and had to be replaced too.

Hello Mr Ron

It sure does, try taking a breath, now put a drinking straw in your mouth and repeat the exercise, a lot longer to get a full lung capacity eh!

Same effect with a few holes missing on the ROS paper.

I would go with H & L too, however there are some brands that the H & L fails before the sheets need replacing, making the ROS into a ocsilllating ROS.

BTW at first I thought you were a Gypsy as you have no home posted, then after investigasting further I see your trains, which then made me wonder with that sort of experience why would you ask the question.

Regardless here is the reply

So if you have a wad punch you can punch the additional holes in your sheets, just use a piece of hardwood as a base and if you want to you could build a template to correctly locate the additional required holes.

This is my half Sheet jig, which you could modify and for a ROS sheet jig

Nice trains !

MrRon,

I use a pair of 8 hole 5” hook and loop Porter Cable model 382 random orbital sanders. I find the on-board dust collection on these sanders is good, but not perfect. A lot of dust is trapped in the sander’s dust collection canister and a very light amount of dust remains on the workpiece after sanding.

I recently gave the Mirka Abranet sanding disks mounted to the Mirka hook and loop pad protector a try. I was impressed. Dust collection seemed improved and the mesh screen continues to cut seemingly longer than the Mirka Bulldog Gold discs I had previously used. But I find the mesh easily tears when you catch an edge, like a dado in the center of the workpiece being sanded.

https://www.2sand.com/sanding-discs/5-inch-hook-and-loop-discs/abranet-5-inch-dust-free-sanding-discs-with-pad-protector

I recently bought some 3 packs of Norton’s ProSand Multi-Air sanding disks. These offer alumina abrasive on a fiber reinforced backing. When placed on the Mirka Pad protector, the Norton disks seemed to last as long as the Abranet and did not tear when catching an edge. The multi-air design seems to perform as well as the Abranet on my sanders (both in cutting action and dust collection). The Norton disks are slightly less expensive than the Abranet.

https://www.amazon.com/Norton-04034-5-Inch-Discs-50-Pack/dp/B0064D6IZI/ref=pd_day0_328_2/164-7851277-5163238?_encoding=UTF8&pd_rd_i=B0064D6IZI&pd_rd_r=7KQ8DDX3APQFFFQ3JQY5&pd_rd_w=1lqm2&pd_rd_wg=3ep6E&psc=1&refRID=7KQ8DDX3APQFFFQ3JQY5

My bottom line is that sanding goes faster and the abrasive lasts longer when sanding dust is removed from the surface during sanding. Since the Norton sanding disks hold up better to edge bumping, are a little less expensive, and perform about the same as the Abranet on my sanders, I will be buying the Norton disks after I run through the Abranet.

Have your say...
