The Tools Needed:
4.25" Core Drill Bit ($75) https://amzn.to/2ZzyT3R
Core Drill Adapter ($12) https://amzn.to/38cGmcN
3/8 chuck Electric Drill
Wire Brush
Gloves
Dryer Vent Kit https://www.homedepot.com/p/Everbilt...

This is the simplest and cleanest way to put in a 4" hole through brick, cinderblock, from an exterior wall so that you can install a dryer vent for your laundry needs.

It might be advantageous to get a 4.5" Drill, as the Stainless Steel Sleeve was a bit tough to slide in, although with a wire brush and elbow greese I was able to get it in.
