Flap Discs

The Flap Disc is a revolutionary hybrid coated abrasive product that combines the stock removal capabilities of a depressed center wheel with the surface finishing characteristics of a resin fibre disc. The result is an abrasive tool that can perform the functions of grinding and finishing simultaneously. A series of flaps made of abrasive cloth are attached to a semi-rigid fiberglass backing in a fan-like arrangement. As the flaps gradually wear during use, there is a continual supply of "new" grains exposed from the under layers.

Features/Benefits

• Lightweight design reduces operator fatigue.
• Easy to use--very little surface pressure required.
• for back-up pads.
• Cool cutting permits light contouring and prevents burning.
• Longer life. Withstands wear up to 10-15 times longer than conventional fibre discs, due to overlapping flap construction.
• Aggressive removal of metal. Equal to Type 27 depressed center wheels with greater safety (does not require tool safety guards).
• Consistent performance as new granules are continually exposed during the life of the product.
• One-step grind and finish reduces down time and finishing costs.
• Grinding angle of conical shape provides optimum contact between work piece and disc surface.
• Tough construction allows for aggressive edge grinding.

Safety Recommendations

• Do not exceed maximum RPM rating indicated on blotter of flap disc.
• Discs without our quick change 5/8(-11 threaded hubs require a re-usable
• adapter commonly used with plain arbored depressed center wheels.

Applications

• Deburring
• Snagging
• Rough and medium grinding of welded seams in one operation
• Edge grinding
• Rust removal
• Working of fillet welds
• Beveling

While Flap Discs perform best on stainless steel, their versatility allows them to work effectively on other materials such as carbon steel, aluminum, wood and plastic.
