The mechanical realities of metal fabrication explain why genuine angle grinder attachments require rigid mounting. Angle grinding relies on direct friction, material hardness differentials, and mechanical downforce. Removing rust, scale, or weld beads demands abrasive grains cutting into the workpiece surface under substantial manual pressure.
If a disc were genuinely levitating via compressed air or magnetic repelling fields, applying downward force would immediately collapse the suspension or force the disc into catastrophic wobble. Even advanced industrial air-bearing tables require steady external pneumatic lines pushing 60 to 90 PSI of continuous dry air across micro-porous carbon surfaces. A compact 18V cordless motor cannot generate the volume or pressure required to hover an operating abrasive disc while cutting metal.
Centrifugal force presents another insurmountable barrier. Without an arbor spindle mechanically locking the disc through a secure flange collar, any disc spun to fabrication speeds would immediately drift laterally and turn into an unguided projectile. The hoax depicts complete stability without side-guide containment, violating fundamental laws of angular momentum and tool safety.
