Make your drip system installation quick, easy, and stress-free with the Hole Punch Tool with Pistol Grip. The hole puncher features a solid metal tip to pierce 1/2 in., 5/8 in., and 0.710 in. supply tubing for insertion of 1/4 in. fittings and drippers. Saves time when you build, expand, or repair your drip system-simply position tubing in the adjustable holder (which has a sliding shelf to accommodate larger-sized tubing) and press the handgrip down to punch the hole. Comfortable pistol grip makes hole punching easier on the hands; a sure-fire solution for reliable, repetitive punching. The Pistol Grip Hole Punch Tool is made of polypropylene (PP) treated with UV inhibitors.
