What are flap discs used for?

Flap discs are incredibly versatile abrasive products, available in a vast array of different abrasive grains and grit sizes designed to cater for all customer requirements. They are the ideal choice for multiple stages and processes within metal fabrication, from stock removal to smoothing out surface imperfections and deburring.

KLINGSPOR SMT Flap Discs offer an aggressive cut while leaving a pleasing finish. Often, one of the SMT discs will take the place of what is now two separate grinding operations - heavy weld removal with a hard grinding disc and then final blending and clean-up with a fibre disc. A built-in fiber-reinforced consumable backing plate eliminates the need for a separate backing pad. Plus you may use your standard angle grinder mounting nut.

Engweld Silver Flap discs are made of alumina zirconia coated flaps, fastened equally to glass-fibre reinforced resin backing plates or glass fabric backing plates. For most metal grinding applications including working of welding seams, deburring, de-rusting and cleaning of castings. Available in Sizes 4-1/2" and Grits: 40, 60, 80.

Klingspor SMT 624 a new twist on convex flap discs. The new SMT 624 utilizes a 12° angled backing plate. This will enable the disc to be used on more severely curved surfaces like pipes and storage tanks. Available in sizes 4- 1/2", 7" and Grits: 36, 40, 50, 60, 80, 120

When to use a coarse gritted flap disc:

For rapid stock removal and where the final surface finish does need to be highly refined or where the customer has no regard for the finish and just wants to get the job done fast. The coarser the grit, generally the quicker material removal rate (depending on the material) but the scratches left behind may be too deep to blend out at a later stage.

This is particularly apparent when comparing finishing processes on carbon steel and stainless steel. The temptation is to always opt for the coarser grains but this can hinder and prolong your finishing options at a later stage.

Coarse grits are also the best choice for soft such as soft steel and aluminium.

When to select a fine gritted flap disc:

Fine grits should be used when a blended and more refined finish is essential to the project. They are typically used at the latter stages of the grinding process to clean up deeper scratches imparted by the coarse grain in stock removal.

Stainless steel for instance usually requires additional surface finishing processes because of the properties that each imparts on the material.

A highly refined finish is primarily used for decorative purposes example or the number 4 finish that is chosen for its anti-fingerprint, anti-bacterial properties in commercial hand rails etc.

After initial stock removal from a coarser grained flap disc or grinding wheel, the scratch would look unsightly on a stainless steel surface.

Finer grits are also more effective over smaller areas of contact and better suited to harder and more brittle materials.
