Screw-Action Irrigation Hole Punch, 8鈥?2 mm

This screw-action irrigation hole punch uses a C-shaped support frame and a hand-turned T-handle to advance the working tip toward the tubing. The gradual screw movement lets you position the tool and apply force in controlled stages. Choose the listed 8, 10 or 12 mm option according to the opening required by your takeoff fitting.

Select by the required hole diameter

The size options describe the intended opening, rather than the nominal diameter of the pipe being worked. Check the fitting鈥檚 installation requirements and ensure that the tubing material and wall thickness are suitable for the selected tool. A hole intended for a rubber grommet can differ from one intended for a directly inserted barb. Confirm the complete connection before choosing the cutter.

Position before applying force

Shut off the supply and release water pressure. Mark the outlet location, place the compatible tube in the support area and align the working tip with the mark. Turn the handle gradually, keeping the tool square to the tube. Stop if the pipe deforms excessively or the tip does not advance as expected; forcing an unsuitable combination can damage the connection area.

Retract the working tip after making the opening, remove loose cut material and inspect the edge. Fit the selected compatible seal or connector, restore water slowly and inspect the joint. Sold as the selected punch option; the group photograph illustrates alternative tools and does not mean that three punches are supplied.
