Taps And Dies Available here. There comes a time when it is easier to cut a thread onto a pipe yourself than try to find the right size at a store. When you reach that point, let MicksGarage.com and our selection of taps and dies come to your rescue. We sell both dies and taps in standard, metric and pipe sizes. They are made of carbon alloy steel, so you know they are built to last. Our dies are designed to be used with any adjustable spanner, and our taps have the drill size permanently etched on their side. When custom threading is the only way to go, use our taps and dies to get the job done.
