Diamond Flap Wheels
UDT Diamond Flap Wheels are used for shaping, beveling and grinding edges on natural stone, marble, granite, concrete and terrazzo, tiles, alumina ceramic, silicon carbide and engineered stone. They can be used wet or dry, have a fast cutting speed and high stock removal rate. A Flap Disk is easier to use and more forgiving than heavier cup wheels, with no vibration.
Our flap wheels are also ideal for sharpening tungsten carbide teeth on machinery such as stump grinders, excavators, trenchers, as well as boring, mining and drilling machines.
Sharpen with the Gold Line #60 grit, and finish off with the #120 grit.
All our flap wheel are made in Korea or the EU.
When used on alumina ceramic tiles, these flap wheels will not blacken the tile like grinding wheels. A variable speed grinder is recommended as low speed work as efficiently as high speed, and the lower speeds keep the wheels cool. Alternatively, swapping flap wheels regularly also keeps them cool. Overheated wheels will loose flaps, and in severe cases, can loose many flaps at once.
#60 grit is the best for stock removal, and #200 and #400 grit is best for polishing (even on alumina ceramic).
The Gold series #60 are best for removing epoxy glue off alumina ceramic tiles.
The UDT Gold Line are a flap disc with extreme grinding and an incredible life time, and very suitable for a straight stone edge. A smooth consistent finish with no chipping is another advantage of these Flap Discs.
These Flap Discs, made from 100% diamond flaps, are the value-for-money option compared to cup wheels.
