2-in-One Drip Irrigation Tubing Hole Punch Fitting Insertion Tools Drip Tube Hole Punch for Easier 1/4 Inch Fitting & Emitter Insertion (Pro Punch Tool Sets)

The hole punch works well. It is a little hard to be perfectly accurate with it though unless Im doing something wrong. It is hard to see where the hole will end up. If I put a mark on the tube, it gets covered up by the plastic body of the hole punch.

The clamping punch works well on .700 or 1/2 inch tubing but foes not cut through 1/4 inch. The hand held cutting is deformed and cuts 90 to 95 percent leaving a chad holding the cutout. UPdate the clamping punch will not punch the oval .700 tubing
