Review on Milwaukee 48-25-2121 8-Inch 16-Inch Selfeed Drill Bit by Richard Summerall

Ideal for drilling holes for 1 1/2" PVC pipe in wood studs. Plumbers always have this size when roughly venting to renovate or expand a room. The quality is good and will last a long time, especially if you don't drive nails or screws into the tree. Pricey at first, but get it when you need it
