I see that these are again on offer tomorrow for £30
Any comments? I have a feeling that someone (TMH?) had used something similar in the past and found it useful, but I can't quite remember.
The spec gives the speed in RPM. I assume that it reciprocates rather than rotates? If so, does the motor speed equate to strokes per minute?
Is it really a file (for use on metal) or just a sanding device for wood?
