RPM for milk frothing? So I had one of those American capitalist/consumer moments where I would have liked to have a milk frother handy. But I just can't bring myself to buy such a frivolous single-use additional material possession. So as a compromise I'll get a Dremel tool.

Concerned that I'll need to step down a Dremel tool to work as a milk frother. Has anyone measured the average RPM of a milk frother? Anyone seen a DIY project to attach a gear reduction to a Dremel? Do I actually need more RPM?

Loss of torque should not be a big issue, even with whole milk. Half and half, that may be another story.
The Ozeri Deluxe milk frother  claims an rpm of 15000 rpm

However I have seen in ikea (and pound / dollar stores) a much cheaper option that to me seems much the same
