Collection: Fibre-Backed Flap Disc

A vulcanised fibre backing is rigid and inexpensive. It takes sustained force without deforming, which makes it the backing for deburring flap discs.

Fibre or plastic

Fibre is rigid, economical and strong. It must be removed from the hub before disposal, and at the end of its life it leaves a hard edge that can mark the part.

Plastic wears down along with the flaps: the disc is used up completely, with no rigid residue or risk of marking, and it can be trimmed with a cutter if needed.

For sustained deburring work, fibre remains the best value for durability. On a finished part, plastic avoids a defect at the end of the disc.

Ceramic grain changes the calculation

A shape-controlled ceramic grain, as in the Cubitron ranges, is cut into micro-triangles that fracture predictably and always present a fresh edge. The disc cuts from start to finish instead of dulling.

It costs more per unit and is justified as soon as operator time weighs more than the price of the consumable, which is almost always the case in production.

Working angle

A flat flap disc works flat or very slightly tilted; a conical disc is made to work between fifteen and twenty-five degrees. Swapping the two wears the disc out in seconds without removing material.
