Ample space usually exists between floor joists or studs to allow drilling holes for plumbing or wiring. Eventually, however, you will encounter a space that cannot accommodate the drill and the bit. When this happens, consider buying or renting one of these items:
- First, a short drill bit: Spade bits come in short lengths, or you might simply cut a regular bit to a shorter length.
- Second, attachments designed to fit into a drill chuck: These hold the bit at a right angle to the drill body.
- Third, drills designed for just this situation: The chuck is positioned at a 90º angle to the drill body. It’s a more expensive solution, so look to borrow or rent a drill like this unless you do a lot of drilling in tight spaces.
Without the proper bits or drills, boring in tight spaces—and being careful to introduce the hole in the recommended middle third of the joist, etc.—can be daunting. Angled holes, whether directed horizontally or vertically, may work for flexible wire, but are completely unsuited for water or gas lines. Further, depending on the incline, steeply angled holes can remove a significant amount of wood and consequently should be avoided when possible.
