Tap and die sets: What are they?

These sets consist of two separate and opposite tools designed for the same purpose. They are made to repair or create a thread in which a screw or a bolt will be added.

To use the kit for multiple purposes, you will have to replace the tap and die insert. They are designed according to the size of the thread you want to create or repair, and the variations are extremely low. In simple words, you will need this set to create a thread on the metal rod, or to fix a thread inside a housing. Once repaired, you will be able to use the piece in question for many more years.

There are no other tools that can do the same thing. You can use tap and die sets only, and you will use them for a simple purpose. In general, they are simple yet advanced tools that can help you repair something that has been broken. If you have welded a metal piece and the thread is damaged, you will have to use tap and die set to repair the thread and recover the item.

You can see a lot of videos online where people make threads for bolts and screws. All of them are made using this type of tool, and all of them are more important than you may believe.

How we rated the 5 best models above?

Now is the time to reveal our secrets. How and why we rated these 5 products as you can see on the list. The goal is to help you find the best kit that will serve you for many years, and that can be used for all applications you have in mind. It must be well-made and robust.

Testing and ranking

The first and the most important thing we will have to reveal is the testing section. We test each kit to the detail, and we will check for all the pieces included. The mission is to see is the set well-made, durable, and does it deserves your attention. Only the best kits are then rated.

The next part is to include the opinions and experiences of the owners who have been using a kit for an extended period. This helps us understand how a kit will perform after many years, and are there some rare and almost impossible issues we weren’t able to see. These reviews and opinions are included in the reports as well.

Pros and cons are mandatory as well

As you were able to see, all products come with pros and cons you can see. This means that you can see the drawbacks of the products and what issues we were able to find while testing them. Let’s face it, all products available on the market have some question or concerns, and it has to be included in the reviews. This should help you pick the best product.

All the additions

Buyers guide for the best tap and die set

Now we will have to teach you how to pick the best tap and die set. There are a lot of factors to consider, and there are a lot of things you must understand before choosing a kit that looks great. By the end of reading this section, you will be able to know how these kits are made, how they work, and which elements are the most important.

Material

All taps and dies must be made from durable metal to withstand heavy-duty usages. Typically you can choose between high-speed steel, alloy steel, titanium-nitrite (TiH), and carbon steel. Of all-metal, we have listed the weakest, and the most affordable is carbon steel. On the other side of the story, we have titanium-nitrite and metals which contain tungsten carbide. They are incredibly durable, and they can withstand any type of use. For most of you, carbon steel elements will be sufficient, and they will last for years. But, if you use your taps and dies all the time, you will need more robust options, some of the metals we have mentioned.

Pieces included in the set

This factor is probably the most important of them all. You need a kit that comes with a suitable number of pieces for your applications. If you are a beginner and you don’t need a lot of pieces, you can opt for 24 elements. These kits target newbies and those who don’t need a massive package with a lot of items included. They are more affordable, and they can be used while working on cars, motorcycles, etc. But, they are not sufficient for those who need the ultimate kit for all kinds of applications.

A more professional set will have more pieces. Some sets have 74 or a similar number of pieces, and they are a great alternative. They are still affordable, and they can be used for more applications and more demanding usages. High-end sets will have 120 or even more pieces, and they are designed and made for professional applications only. You need to invest in a set that has precisely the number of pieces you will use, not the one that will stay unused for years. Quality and the number of pieces are more than just essential factors.

Manufacturer

Some brands are known for making high-end taps and dies of superb quality and excellent performance. These brands include Irwin, which is known for its high-end products. They are not very affordable, but the quality is stunning. We recommend this brand for professionals and those who need reliable and durable taps and dies.  Craftsman is more suitable for beginners and intermediate users. The quality is still high, but the price is much more affordable. Pick a brand that offers you quality and a price you are comfortable with.

Case

You need a case to store your taps and dies. There are a lot of variations here, and you can see that each one is different. In general, there are two or three types of cases you need to look for. The first type is low-end cases that are very lightweight and come with basic features. They are designed for light-duty purposes. Heavy-duty cases are much more robust, and they can withstand all the usages you can think of.

Keep in mind that all the pieces must lock in place when inside a case. This is almost always included feature, but we still have to make the point. When the pieces are secured, they won’t fell, or you won’t lose them while transporting the set. It is a safe and vital factor we all liked.

Types of usage

How will you use your tap and die set? If you are planning to use it for softer materials and you will use it occasionally, you need a more affordable option, which will probably be made from milder types of steel. This means that it is a durable alternative, but it comes with decent quality. It will last for years, and it will be helpful when you need it.

If you use it for steel and hard metals, you need a set that can withstand that type of use. This simply means that you need a harder kind of iron, and you need a set that can withstand the heaviest usages of them all. Look for tungsten carbide or alloy steel, and you will make the right choice.

Rust-resistant finish

All taps and dies must be immune to rust all the time. You will need to look for models that are made or coated with chrome or satin finish. Steel will rust within days if not protected. A rusted piece won’t be able to last, and it will use its sharpness. This translates to poor results and the fact it will likely break at some point. All the sets we have mentioned above are immune to rust, and there won’t be any issues regarding the matter.

Fit

Fit is used to describe how dies are inserted into the main piece with a handle. Fit should be perfect, and it must not move at any given moment. When the die moves, you will be unable to repair or make an ideal thread, which hurts the strength and durability of the thread. You can also make it diagonally, which is a severe issue, and you will have to solve it as soon as possible.

The shape of the dies

Almost all kits come in hex shape. This is due to the fact hex shape is the strongest of them all, and it can last and withstand any type of stress or issue you can throw at it. Other forms may not be ideal, and they are usually reserved for low-end alternatives. Hex shape is also more effective when it comes to repairing the thread on the hard steel rods and metals. A user can use more pressure and more force to complete the task.

Measurements

You can choose between inches and metric sizes. It is up to you which type do you need. In a nutshell, you will need a kit that comes with a single measurement type or with two. It is up to you which one do you need, but keep in mind that it should be chosen according to the location where you live, meaning which measurements are used there. We all know that people from the United States will be more than just satisfied with imperial metric pieces, and this is probably the leading choice.

Some kits come with mixed measurements. They are appealing, and you will use them for an extended time, but you will also encounter all kinds of issues. You can mix the pieces, and you will need more time to find the one you need.

Handle

Let’s face it; you will need a lot of energy to repair a damaged thread and to make sure it is durable. All of that stress will be directed across the handle. Old handles are simple round rods that are not very comfortable. You will have a hard time, and you will usually have to use cloth or pipes to make the handle more comfortable. It is an excellent addition having a set that comes with ergonomic handles. What this allows you is to use them for a more extended time and more complicated processes.

Sizes

It is usually linked to the number of pieces in a set, but you should pay attention to the smallest and the most prominent piece included. What this means is that you can enjoy the versatility, and you will probably be able to use the set for smaller or bigger purposes, according to your needs.
