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.
