Drilling Holes: Notching and Boring Holes in Wood Studs (DIY)
Keep the holes centered on the studs and a consistent height off the floor. Drill holes into a stud at least 1/4 in. oversize, especially for hot water pipes. If you don''t, they''ll make annoying sounds as they expand, contract and rub along studs. Joist hanger manufacturers sell wrap-around, stud reinforcer plates.
Bottom Hole Assembly
A bottom hole assembly (BHA) is the lowest part of the drill string, extending from the bit to the drill pipe. It is a complex assembly of components that are designed to drill the well, control the wellbore, and provide the driller with information about the formation. The BHA can consist of the following components:
