The ROLOC discs are a lot tougher than “3M Radial Bristle Discs” or “Sanding Wheel Brushes” from McMaster-Carr. You can really go at it and scrub a piece with a Roloc disc.
The Roloc discs work best on almost flat things or on the outside of bowls or hollow forms.
On the inside of the above small bowl I would still use a “Sanding Wheel Brushes” from McMaster-Carr. See my “Sanding Wheel Brush” blog entry.
For delicate things I would still use a “3M Radial Bristle Disc”. See my my “Power Carving Textures” blog entry.
3M Bristle Discs
3M makes two different “Bristle Disc” products. A “3M ROLOC Bristle Disc” and a “3M RADIAL Brislte Disc”. See photo for differences.
The yellow Roloc Bristle Disc that I like is 3″ diameter, 80 grit. Around $15 on Ebay on 10/2020.
They make 1″, 2″ and 3″ sizes. Green is 50 grade. Yellow is 80 grade. White is 120 grade. On the 3M website Grade=Grit. The 2″ discs are around $11 and easier to find.
You will also need to purchase a Roloc Disk Holder (Mandrel) for your drill. You can get good package deals (1″, 2″ and 3″) on Ebay or Amazon for around $10 on 10/2020.
I like to use my Roloc Bristle Discs in an angle drill. I like drills with real METAL gears. I don’t need to waste my time and money on the cheap crappy drills with plastic gears on Amazon. I get my angle drills from woodturnerswonders.com because they have metal gears. You can see the metal gears in the product photos.
Here is what the finished piece looks like. I like it!
