Professional Gun Punch 3mm

One of the few tools used in drip irrigation installation, a hole punch tool is essential (literally!) to building a system that used 1/4" tubing or fitting, or where drippers will be inserted into 1/2" or larger tubing. A hole punch like this one is specially designed to create the correct size hole for drippers and 1/4" fittings to fit into without leaking. The "pro" model includes a 3mm punch tip, squeeze-action punch lever, and removable sleeve to accommodate 3/4" and 1/2" tubing. To use 3/4" tubing, push the blue insert by the punch tip to the side until it slides out, making sure to replace it before using with 1/2" tubing. 

TIP: DO NOT other tools to make a hole instead of an approved hole punch! Awls, screwdrivers, nails, drills, etc. punch uneven holes, risk piercing through the other side of the tubing, and leave jagged edges that will result in leaks. Only use an approved, purpose-built hole punch tool when installing a drip irrigation system.
