I purchased this Bosch die grinder because the price & size was right. Or so I assumed. On Amazon they list it as variable speed, which is actually 100% INCORRECT. It is most certainly 1-speed. I used it, time passed, thought I'd live with it. But now (that its too late) having buyers remorse. For any tooling that is much larger than typical small diameter burrs, especially like 2" flap or abrasive mesh pads/wheels, its actually borderline scary dangerous. The 'real' variable speed models are bigger, heavier & more $$.
Is there any kind of aftermarket 'box' I can acquire to control the speed externally? ie plug the grinder into the box & turn a dial to give me progressive rpm? I know this used to be a thing back in the day with Variacs (does that mean variable voltage transformers?). But how would I know this motor is compatible? I assume true variable speed motors in tooling must have brushless motors & dedicated controller circuit board thingy inside? In case you were wondering based on my sophisticated electrical vocabulary I am not a PhD electrical engineer - LOL
