A Favorite! Ergonomically designed to make snapping a hole into the 1/2-in poly tubing even easier. This tool has side guides to slide over the 1/2-in tubing to help hold into place and also act as a safety shield to the sharp hole punch tip. It also has 1/4-in side slot to securely hold the barb ends of 1/4-in fittings while pushing 1/4-in vinyl onto its other barbed end. The center channel to securely hold 1/4-in vinyl tubing and coupler or dripper while inserting into the poly tubing. The removable yellow cleaning tool that will clean the orifice of the Micro-Sprays and violet flow-controller. The flat, round-head goof plug fitting will easily give leverage to inserting into the poly or the 1/4-in in-line drip tubing. The bright-blue color makes this punch tool easy to find if misplaced.
