Thermal Fusion Drill Bits

[D.808]

Have not heard of Thermal Fusion Bits. But at work we had some Cryo Tools, suppose to stay sharper last longer. I couldn't tell the difference from a regular good bit and blade.

I just saw an ad for these bits for most metals inc. aluminum. The idea sounds possible and the results look positive. Has anyone ever used these bits for work on their bike? Any draw backs if you did or can foresee ?
