dremel sanding buffs

Greg,

I recently had the same experience. I am going to try their detail abrasive brushes next. Here is the link:

I'll let you know how they work.

to Greg:
I was the inventor of these little bristle brushes...for the 3M Company...Dremel buys them from 3M...they have a learning curve and you want to run them a slow as possible to do the job you want done. They were designed for the jewelry industry. They come in a 3/4", 1", 2" and 3" diameter. They are available through Rio Grande too and you can make your own brush. http://www.riogrande.com/Search/bristle-brushes ... many pages of brushes.

those look good for large areas but I do a lot of small detail things Im not sure it would get int the crevasses with out sanding down the detail

The 3M Radial Bristle Discs come in a 3/4 inch diameter and a 120 grit...you can but them as separate discs and stack 5 or 6 together, which makes a nice, small detail brush for a Dremel tool. Run the brush fairly slow...5000 to 10,000 rpm.
Rio Grande sells the discs...I think Dremel only sells a brush they make with the 3M Radial Bristle Discs.

Otto Frei is the cheapest place I have found to get these. The offer quantity discounts, and you get a free mandrel with every bulk pack. They have all the sizes and grits, and ship very fast.

dehrlich - When I worked at 3M Otto Frei was one of our better distributors...excellent info !! I will check out D&M Woodworks...

I just bought some of the 3M bristle brushes (3/4" and 1") , and found them to be pretty good. I bought them from McMaster-Carr along with the mandrels, and they're a lot more affordable. If you run them at low speed they tend to last.

I'm only using them one at a time instead of stacking them up though.

I suppose I should have stacked them up to prevent grooving in my background.... They're not very aggressive on Spanish Cedar, until you don't want them to be.

Are they cheaper with McMaster-Carr than with Otto Frei? By chance do you have the link you ordered them from?

Based on rcadges advice, I ordered from Otto Frei. I received them last night and I tried them out. The work well. Pretty inexpensive around 1.10 each bristle. I did find the faster you spin them, the faster they wear out. I put two together. They did a good job.

Proctorw,

Pleased to hear that you are happy with the bristles from Otto Frei.

I would not want to be with out them.

I would suggest stacking 3 discs as a minimum for about 99% of the time...4 to 6 is best. I would use only one disc for very delicate sanding of a very finely detailed spot at slow speed. These discs were designed to be used on soft metals in the jewelry business, but have found a home in woodworking. They have a learning curve, but once you get the hang of them, they work very well.(says the proud papa)
