4 mm (.125") Palm Punch for Spot Spitters

This hole punch tool is specifically designed to punch holes allowing you to connect 1/8" poly tubing directly to 1/2" or larger tubing without a fitting! That's pretty cool, even if it's a bit of a niche use. We'd suggest not using this hole punch tool for anything else. If you're looking for a normal hole punch tool, check out the A019 or A035. If you need a 4mm punch for installing katif-style drippers, use the A035 and get the green 4mm tip.
