Tap and die sets are an essential kit to have available if a fastener or fastener hole is threaded and then rendered unusable. By using a tap and die kit, a new thread can be cut, or a damaged thread repaired, especially if it has threaded or has a lot of corrosion on it from years’ worth of build-up. A tap and die set generally consists of the tap and the die. The tap is designed for internal thread cutting, so this would be used on the fastener hole or a nut, whereas a die is used for the external thread, like on a bolt. Sets like these are most commonly used for:
• Automotive applications and repair
• General maintenance workshops
• DIY
• Machinery repair

Tapping and threading are the processes that are used to produce screw threads. Tapping uses the tap part of the set and creates internal threads. Threading is the process used by the die to cut external threads.

By choosing a HSS tap and die set, you can be sure that you are selecting the most durable and hardy material to ensure you are achieving a quality result every time. HSS has a higher abrasion resistance and can also withstand higher temperatures without losing its durability and hardiness, making it ideal for continuous use. It also cuts faster when working with stubborn materials and lasts longer.
