Eli X. ★★★★★ Oct 21, 2026

It took me a minute to figure out the right angle to push it in, but once I did, the hole was clean and perfectly sized for the drip fittings. Much easier than trying to poke holes with a screwdriver or knife.

Finally, a simple tool that makes adding drip emitters to 1/2" poly pipe truly effortless. The punch creates a clean 4mm hole every time with no jagged edges. I installed a dozen drippers in under five minutes without any leaking.

I was nervous about cracking the tubing, but this tool makes perfectly clean 4mm holes with almost no effort. It's small and simple, but it did exactly what it needed to do for installing my drip emitters.
