Quick Answer: The Milwaukee M12 FUEL right-angle drill and Ridgid PEX crimp tool kit are our essential plumbing repair picks. Modern plumbing repairs center on access and connections, and these two tools let you drill through joists in tight spaces and make reliable PEX connections that meet code in every jurisdiction.
What to Look For
Plumbing repairs happen in the worst possible spaces: under sinks, between joists, inside walls, and in crawl spaces. A right-angle drill or attachment is essential for drilling through studs and joists where straight drills cannot reach. Pipe cutters sized for your system’s pipe material (copper, PEX, PVC) produce clean, burr-free cuts that prevent leaks. For PEX work, choose between crimp, clamp, and expansion connection systems based on your local code and preference. Channel-lock pliers in 10 and 12-inch sizes handle most fitting work. A basin wrench is the only tool that can reach faucet mounting nuts from below. Headlamp or magnetic LED light is mandatory since plumbing work always happens in dark cavities.

How to Choose
Start with a right-angle drill if you do any plumbing that involves running new lines through framing. The Milwaukee M12 FUEL is the gold standard for plumbers and serious DIYers. Add a PEX connection tool based on your preferred system: crimp rings are cheapest, clamp rings are easiest for beginners, and expansion fittings offer the most reliable connections but cost more per joint. The powered copper cutter is a luxury that pays for itself if you do regular copper work in tight spaces. For occasional plumbing repairs, manual versions of pipe cutters and PEX crimpers work fine at a fraction of the cost.
FAQ
What PEX connection method is best?
Expansion fittings (ProPEX/Uponor) create the strongest connections and are the only type where the pipe end can be visually inspected after connection. Crimp rings are the most economical and widely used. Clamp (cinch) rings work with a universal tool regardless of pipe size. Check your local code for approved methods.
Do I need a right-angle drill for plumbing?
If you are running new water lines through existing walls or floors, a right-angle drill is practically mandatory. Standard drills cannot reach between joists and studs where plumbing runs. Even for repairs, the ability to drill access holes at angles saves hours.
What are the essential hand tools for plumbing?
At minimum you need: 10 and 12-inch channel-lock pliers, a basin wrench, a tubing cutter, a pipe wrench, PTFE tape, and an adjustable wrench. Add a PEX cutter and appropriate connection tool if your home uses PEX. A good headlamp is arguably the most important plumbing tool of all.
