I’ve been working on cars for over 25 years. 10 of those I spent my day job at an industrial machine shop, 10 of those I worked at an auto parts store... this past weekend I was prepping my trailer for a new wiring harness. How is it that this is the first time I’ve ever used one of these magic drill bits?

I mean, W T F. Happy, but so unhappy I never tried this before!!!!
