Aluminum Oxide Flap Wheel M8 (AO)

Aluminum oxide is a popular choice among industrial professionals because of its fast cut-rate and long life. This mineral makes a tough, durable abrasive that self-fractures to expose fresh cutting edges, whereas traditional natural abrasives dull more quickly. Due to its fast cut rate, hardness, and strength, it is widely used in grinding applications in addition to sanding and finishing applications.

Flap Wheels with Shank

Flap wheels with Shank are suitable for grinding small area, dead angle, inner hole surface, and slit gaps that are difficult to reach. The Features of the abrasive clothes are various with multipurpose application capacity. It is flexible and rich in tensile strength. It could remove the burr and uneven, rough surface with fast grinding force efficiently, meanwhile, can make sure the performance result achieves a slightly finer surface. It is a good product for pre-painting or mirror finishing preparation procedures.



High flexibility to optimum adaptation to contours


Steadily high stock removal through the entire tool life and aggressive coated abrasive resin is freed up constantly


The design of opening spaces and flat bonded make the abrasive tools can process a face-down position, so can touch closely to the edges and corners.

Work on edges




Weld dressing


Fine grinding in multiple steps

Safety Warning of Aluminum Oxide Flap Wheel M8 (AO)


Safety Warning of Aluminum Oxide Flap Wheel M8 (AO)


Please try to choose an operation indoor environment and wear protective guards and goggles.  


Never exceed the recommended maximum permitted rotational speed for safety reasons.


In order to have a good stock removal rate, quality of surface, and thermal loading on the workpiece, the best performance would be with a recommended cutting speed of 15-20m/s.


Don’t push and increase the pressure during the processing to achieve a finner surface looking, but try to switch to diffirent grit flap wheels.


Safety Warning:

The clamping length between shank and grinders should be more than 15mm.


Never exceed the maximum safe speed when the shank is extra long. Try to consult your sales to check the safety rotating speed before use.
