PRODUCTS / Flap discs
Flap discs
Flap discs use overlapping coated-abrasive flaps for grinding and finishing metal with an angle grinder. Abrasive grain and grit influence the result.
Where it helps
Combine stock removal and a more controlled finish in one operation.
What to consider
Not suitable for cutting. Pressure, working angle and grit selection affect service life and finish.
Catalogue range and selection
- Page 10 lists TFD 822, TFD 812 and MFD 852 Extreme. Page 11 covers TFD 814s for angle grinding and MST 624.
- For weld removal on metal or stainless steel, start with the amount of stock to remove. For the transition to finishing, see the special TFDC / TFDF discs combining abrasive cloth and surface conditioning on page 24.
- To select a flap disc, provide diameter, grit, workpiece material and the required result: weld removal, edge blending or finishing.

What to compare when choosing a flap disc
Start with the diameter and bore that fit your grinder. For example, the Ø125 × 22.3 mm TFD 822 zirconia disc is listed in P40, P60, P80 and P120. The 12° version has its own options in the table.
Weld grinding and final finishing call for different results. Tell us the workpiece material, your current grit and the finish you need so we can compare suitable series.
