3M's best quality, these 1/8" thick bonded wheels contain proprietary synthetic Cubitron™ - one of the hardest, longest lasting abrasives available.
Cubitron particles are somewhat less sharp than aluminum oxide, but they are harder and wear down more slowly.
They are especially suitable for high heat applications such as working on tough metal substrates - like stainless steel or cold rolled steel.
With a bonded construction, the abrasive is distributed throughout the structure - not just on the surface - for longer useful life.
These wheels feature a built-in spin-on hub for 5/8"-11 thread - for quick wheel changes.
The substantial spin-on hub provides support for the wheel, so an additional back-up pad is not necessary.
