- Durable construction: Punch tools are made from high quality plastic and metal. They are strong and the punch heads are polished to resist dulling for long use. - 2-in-1 design: Includes a drip tubing punch and a 1/4 inch fitting insert, enabling both hole punching and fitting insertion in one tool. - PE pipe compatibility: Perforates polyethylene pipes for installing drippers and micro nozzles. Suitable for PE pipes with 16/20 mm diameter. - Precise hole size: Punch holes measuring 3 mm (0.118 inches) for a snug fit that minimizes waste and helps maintain proper pressure in your drip system. - Use scenarios: - Install new drip irrigation lines in a garden bed by punching 3 mm holes in 16/20 mm PE tubing for emitters. - Add 1/4 inch fittings along the tubing during setup or maintenance. - Expand or repair existing drip systems in greenhouses or landscape beds without replacing pipes.
