Back the tap out frequently to get rid of debris that builds up in the threads.Ĭlint’s career has covered nearly the entire realm of audio and video production. As with using a die, adding oil is a must. Next, place the tap into the nut and begin turning it down by hand being cautious to keep it perfectly straight to the hole. To begin, place the tap into the provided wrench and secure it. You can always drill out the hole and re-tap it for a slightly larger bolt. If you encounter completely damaged threads, don’t panic. Based on its location, this may even be impossible. This keeps you from needing to try and muscle the gauge into a worn-out bolt. For those doing a nut on its own, you would want to use the actual matching bolt to set the size. If you don’t have a matching bolt, use a gauge to select the correct size for the nut or hole you want to thread.

Using a tap to thread (or re-thread) a nut is just as easy. Rethreading Holes and Nuts with a Tap and Die Once the die makes it far enough down that the bolt sticks through the top you will know you are finished. This is to be expected and is akin to drilling into wood with a large bit. Every few turns you may have to back the die out a bit to clear the threads and allow it to cut better. This also extends the life of your tap and die set.Īs you thread the die down onto the bolt you will feel it quickly begin to catch. Use this advantage to add lubricant without removing the die. Most tap and die wrenches have an open top. We recommend using a little cutting oil to lubricate the die and keep it cool during use. It’s more apparent when you engage in longer thread lengths. This is inevitable when tightly rubbing two metals together. When you begin to rethread the bolt it may start to heat up. Once you have the bolt secured, carefully align the die so that you don’t go down on an angle, but straight down the bolt. Locate some rubber (like a bibcycle inner tube) and place it in the vise jawsĪlign the Die and Begin (re)Cutting the Threads.Lining up your holes and keeping them straight and level presents the biggest challenge with these bits. We’ve tried them in various sheet metals and plate steel. Provided you stick to the recommended materials and lubricate the bits during use, these provide super-quick hole tapping. With how much caution you need with manually tapping holes, it’s a wonder how these work.

These go into an impact driver or drill, letting you both drill and tap in one step. You may have seen some of the new drill and tap bits. What About Combination Drilling and Tapping Bits? This gives you the required leverage to spin it around and guide it on its cutting path.

Most dies fit into a special wrench that holds them fast. This helps them ease into a bolt or nut and gently re-carve the threads as they were intended. Taps and dies both feature tapered threads. Manufacturers also have very small small and very extensive kits. Keep in mind that these sets come in both metric and SAE. Many of these thread checkers exist on the market and you can find one that works well for you.Īfter determining the TPI of a bolt, you can then select the die that corresponds to it. Some look a little like a small pocket knife. These use a number of different “blades” that help you match the correct TPI of a bolt or nut. Most tap and die systems, include some kind of gauge. You need this to grab the correct tap and/or die for the bolt, nut, or hole. Find the Correct TPIīefore you can start threading, you first have to determine the number of threads per inch (TPI). With the right amount of oil and care, you can quickly and consistently cut or repair threads for machined screws and bolts. You use a “die” to either cut or repair threads onto a bolt or piece of metal. The metal of these thread cutters exceeds the strength of most sheet metals.
