Sure, cheap tools are cheap. Let the buyer beware.
For some tools and at some prices it's worth a shot.

We used to buy cheap $2 screwdrivers by the packet of 10.
Really good value as I can bend them to suit a job, cut them down, file them off ...............

Cheap 'cutting/grinding/drilling' tools are generally a bad idea. You need good steel for abrasive work.
Cheap tools don't have good steel.

I had a job where I had to bend the handle of a spanner 180 degrees to get it to fit the space.

Bought 3 cheap spanners the right size.
Bent and ground them down to fit.
One broke, 2nd one was a success.

Cheap tools can be ok
