What Is a Tap and Die Set?

In a nutshell, a tap and die set is a collection of tools that we can use to create screw threads (or bolt threads). As the name suggests, it mainly consists of a ‘tap’ wrench and a ‘die’ stock.

A tap wrench is used to form and cut the female portion of the screw system (i.e., the nut), while the die is used to form the male portion (i.e. a bolt or a screw).

Thus, the process of forming threads using a tap is called tapping, while the process of using a die to form the male portion of the system is called threading.

You can use the taps and dies to add new threads for older screws (and bolts), to repair existing threads, or to create a totally new thread system from scratch.

The taps and dies in the set can vary according to their diameter, hardness, and pitch, among other vectors.

You’ll need taps and dies in different diameters because you will need different diameters of holes to fit different sizes of bolts and screws.

Varying level of hardness, on the other hand, is necessary so we can work with different materials of varying hardness.

Last but not least, pitch will also dictate the types of threads created by the set.

Below, we will discuss the different types of taps and dies further.

Different Types of Taps and Dies

A common misconception is to think that all ‘taps and dies’ are made similar, but as discussed, there are actually a lot of variation with these tap and die tools.

First, taps come in three main types:

  1. Taper taps: With their tiny and flatter threads, taper taps don’t require much force to use, so they are also great for beginners. Used for initial threading to start a hole, then we can use other taps to create a bigger hole according to your needs.
  2. Plug taps: The most common type, useful for both initial threading and when finishing the holes. Plug taps feature a flattened thread at the beginning but not as flat as a taper tap. So, they aren’t easy to use as taper taps, but at the same time they cannot thread as fully as finishing taps.
  3. Finishing taps: As the name suggests, it’s the best option for finishing a thread pattern. Finishing taps can completely cut the thread to the bottom of the hole. Shouldn’t be used for initial threading because they possess very small and unthreaded end, so it’s very difficult to use it to initiate threading.

Similar to taps, dies also come in mainly three types: die nut, circular die, and split-circular die.

  1. Die nuts: Used to sharpen existing threads but cannot be used to create new threads
  2. Circular dies: The most common type and you can always find circular dies in any set. Used to cut threads into the exterior of screws or bolts.
  3. Split-circular dies: As the name suggests, can be split in half and you can only use half of them, allowing them to accept larger materials. Used to cut shallow threads in initial cutting, and also to cut deeper threads as the die is tightened around the bolt.

In sets that include wrenches, there are also three different types of wrenches:

  1. Tap wrench: Looks like a long and thin bar with an adjustable teeth in the rectangular opening. The tap wrench will fasten around the tap to secure it so you can cut threads without slipping.
  2. Die wrench: Looks relatively similar to a tap wrench, but the opening in the middle is shaped to fasten around dies. The dies are fastened to the wrench with the set screws.
  3. Ratcheting wrench: This type of wrench allows us to cut clockwise but the thread will not loosen when the wrench is rotated counterclockwise (unless you release it). This allows a more seamless cutting method that’s not as tiring as the usual hand-over-hand cutting technique.

How To Choose The Right Tap and Die Set

Before you purchase a new tap and die set for your next project, you might want to consider the following factors to ensure you’ll get the right tap and die set according to your project’s needs.

What’s included in the set 

As we’ve discussed above, there are various types of taps, dies, and wrenches that can be included in a set, and different sets will also include different numbers of parts.

For example, a simple tap and die set specialized for woodworking may only include three pieces in the set (a tap, a die, and a wrench), while there are also sets that include more than 100 pieces.

So, first figure out your needs:

If you will use it for complex metalworking, then you might want a set that includes more diameter sizes and hardness.

On the other hand, if you are only going to use the set for simpler works, then you might opt for a simpler set to save money.

Typically the more tools included in the set, the more expensive the set will be, but not always.

Storage Case 

Some tap and die sets don’t include a storage case in the package, but most do.

You’d want a set that offer high-quality and durable storage case to prevent the tools from various damages from weather damages, rusting, impact damages, and so on.

If the set offers a durable steel case or a high-quality plastic case, then it’s a nice plus point.

Also, consider how secure the case will hold the tools in place when it’s closed. So, if you move the case around, the tools won’t fall out of place, which can be frustrating when you are looking to use the tool in a hurry.

Measurement Systems: Metric vs SAE 

Tap and die tools with metric system are measured by the distance between the thread crests in millimeters.

The crest is a protruding part (can be external or internal), and there are two flanks that connects the crest to the root. As you can see, a tap and die set with a metric system can be quite confusing to measure.

On the other hand, a SAE (Society of Automotive Engineers) tap and die set is typically easier to understand, and they are measured in TPI or threads per inch.

You can simply hold a measuring tape up to the thread pattern and count the number of complete threads in every inch.

You’d want to get a tap and die set according to the measurement system used in your location, and some tap and die sets also include a pitch gauge in the set, which is a specialized tool you can use to quickly measure the number of threads regardless of the measurement system.


Material is obviously an important consideration when choosing between different tap and die sets. It’s important to remember that only sets made of harder materials can cut through the hard materials.

Sets made of aluminum (soft metal), for example, are typically intended to use on wood materials, and you won’t be able to use them to cut steel or harder metal materials.

If you want versatility, you might as well choose sets with moderately hard material like alloy steel, but if you often work with harder materials, then you’d want a set made with titanium, cobalt, or carbon steel, among others.


Selecting just one tap and tie set out of the five in this list is indeed a very daunting task. There are so many different products available in the market, and each product offers its unique take and include different tools in the set.

For our absolute best pick, although admittedly this is wasn’t easy, we’ll go for GEARWRENCH Ratcheting Tap and Die Set.

It includes 114 different pieces of tools in the set made of carbon steel, and include a rugged, high-quality case.

However, that’s not saying the others on this list are bad products. We are confident that based on our tests, these five sets we have reviewed are indeed the best choices you can you can make right now at their price-points.
