just the thing to clean up edges of aluminum. Saved countless hours already making my fuselage formers compared to filing. A must have item.
3M 7S FINE GRADE DEBURRING WHL
Excellent fine grade wheel takes all marks out of the parts after using the medium one
3M 7S FINE GRADE DEBURRING WHL
A must for aluminium polishing and edges.
Bought this same wheel when I built my RV8 several years ago and decided to get a new one for the new project. One of my heavily used items in my shop. Could not live without it. A+++
Great timesaver for deburring aluminum edges. I would recommend to any builder of aluminum aircraft - well worth the cost.
The 3M Scotch-Brite Deburring Wheel (7A version) is a great way to clean up metal parts after cutting. Its fine enough to polish the surface well enough to remove scratches that could create stress cracks but is also fast enough to wear down large burs. I ended up buying a Harbor Freight polisher as it had a long enough arbor to accommodate the wheel size. This is definitely a must-have for metal finishing.
Works great for deburring sharp edges on panels.
The wheel that I received was seriously out of balance and creating a lot of vibration to the point that it was unusable. When trying to exchange the item for another wheel, I was told that since it had been in the machine (even though that was just turning the machine on for a few seconds), that it would have to be warrantied (as opposed to returned) and it could take 4 to 8 weeks to have 3M verify the defect and then get my money back or get a credit. I expected better quality control from 3M. Completely unacceptable in a $115 wheel.

The 7A, 12-00875, is a medium grade cut and polish wheel, and the 7S, 12-00948, is a fine grade light deburring wheel.
The 7S is 1" wide and the 9S is 1/2" wide.
It is a 6" wheel. We are not sure if it would work on a 8" grinder. You would need to check with the grinder manufacturer to see if it can use 6" wheels.
