This handy hole-punch reduces fatigue and simplifies insertion of drippers/emitters, 1/4 in. barbed couplings, and other barbed Drip devices into 1/2 in. Drip irrigation tubing. Sharp tip quickly creates the perfect size hole for secure, long-lasting connections. Constructed of tough polymer with a built-in stop to help avoid puncturing through both sides of tubing. Two usage tips: Applying a slight twisting action when puncturing holes will provide an even easier penetration. Attaching a lanyard through the hole and around your wrist puts tool right where you need it and helps prevent loss.
