The only opportunity you need to use a drill when installing a drip irrigation system is when you are installing the drip emitters. They’ve barbed connectors made to fit into 1/4-inch polybutylene tubing, and should you install them directly to the 1/2- or 5/8-inch main PB waterlines, then you need to make holes for them. You can purchase a punch to produce these holes, but the punch can be difficult to use, particularly in sunny weather once the tubing is hot and pliable. A drill makes the job of punching the holes simpler. Fit a variable-speed drill with a 3-16-inch drill bit. It will make a hole slightly smaller in diameter than the barbs of the emitters, ensuring a tight fit.
