Flap discs are overlapped pieces of coated abrasive arranged around the outer rim of a hub and adhered with strong glue. The overlapping method allows for more abrasive material to be mounted on the hub and improves disc life while keeping the benefits of the higher grain exposure. Like the fiber disc, the grain types and grit sizes can be changed according to the cut rate and surface finish requirements.
Normally these products are available in three configurations:. Type 27 for blending and standard work. Non-woven abrasive discs are composed of fibrous material where the abrasive is bonded to the fibers by a resin.
This random assortment of grain and fiber gives the disc a compliant cutting action as it conforms to the point of contact more readily. The result is a better surface finish or lower surface roughness average Ra. Coarser grit non-wovens, while not as aggressive as fiber discs, flap discs or grinding wheels, can still provide an aggressive cut that may be sufficient for the application.
An example of a heavy weld showing the height that is well suited for grinding wheels and coarse grit fiber discs. Each of these abrasive product families has a place in the post-processing of a weld. Now that each family has been defined, here are some application examples where they would be most useful. Confined spaces where grinding wheel breakage could pose more of a risk. Blending the weld to the parent material without overgrinding.
Small work areas where a small angle grinder is the tool of choice. Conformability to the weld to blend into the parent material where grinding on either side of the weld is allowable. Better surface finish than a grinding wheel or fiber disc, grit for grit.
Removing weld splatter without overgrinding — 50 grit or finer. Difficult to reach welds — fillet welds that require clean up. Frequent abrasive product changes are not practical — working in areas that are secluded or where there are limitations on how many tools the welder can bring, such as scaffolding.

Safety Rules for the Disc Sander. Always wear proper eye and ear protection, and a dust mask. If you're doing a large amount of sanding, you should wear a respirator.
Don't turn on the power with the stock laying on the worktable or already in contact with the disc. Never reach over the disc or behind it while it's running. Always sand on the downward motion side of the disc Figure The rotation helps to hold the workpiece against the table. If you sand on the upward motion side, the disc will lift the piece off the table and cause a kickback.
The one exception is when you use the quill to advance the disc. The rotation of the disc may lift wider boards off the table. When you use the quill feed to advance the disc, attach the quill feed lever to the side of the power plant where you can reach it most easily.
Always use the worktable; add the extension table if necessary. Never sand without a table supporting the stock. When using the quill feed to advance the disc, back up the stock with the rip fence.
