This Neiko set is made up of large gauge taps and dies. There are ten UNC taps and dies, and ten UNF taps and dies. The set is made of titanium and seems to be well made.
The overall reviews are positive, with most people pleased with both the price and the additional number of sizes. The taps themselves are durable, with no concerns of them shearing off or wearing down over time.
The only issue some people had was the lack of plug sizes large enough for all of the sizes. Others mentioned that they needed to use a bit more lubricant than they had originally expected.
There isn’t much more information available on this set, which is normally a red flag for us. However, the reviews are so good, and the ratings are excellent as well, so this may just be a case of very little needed to say or extras to explain. The set performs as intended, and there are few to no customer issues, so that very well might be the case.
Neiko 00912A Titanium Coated Tap and Hexagon Die Set – Well-made and conveinent for threading
The Neiko tap and die set comes in either standard or metric. The entire set is made of GCr15 alloy steel and coated with titanium.
The metric set comes with ten coarse taps and dies and six fine thread ones. There’s also a 1/8″ tap and die, and then the wrenches that come with them. Neiko also includes a screwdriver and pitch gauge.
Neiko’s set includes everything needed for threading, meaning that you won’t have to bring another kit along. This set is generally well reviewed, with customers pleased for the amount of value they receive for the price.
Overall, most people using this set on softer metals and plastic, not on harder metals like cast iron.

All in all, most buyers are pleased with the value for their money.

The Tekton set is pretty poorly reviewed, with many customers expressing frustration about the poor handle quality and the fact that the bits are difficult to work with. Many had bits or handle break off in the middle of their first project, and their frustration is understandable.
The overall product is a little bit Jekyll and Hyde, with some customers reporting a nice experience, but others not even getting through one task or project without experiencing problems. Tekton’s customer service is involved online, and quick to offer replacements to belay any frustration, but the overall effect is still concerning.
IRWIN HANSON – Tap and Die Set with Drill Bits
The Irwin fractional and metric set come with a variety of different options, including the number of pieces (ranging from twelve to one hundred and seventeen) and whether you’d like fractional, metric, or fractional and metric.
The one hundred and seventeen piece set is the one to choose for the greatest variety, as it comes with many different dies and taps in a variety of types. There are six machine taps and dies, ten SAE taps and dies, two pipe taps and dies, and sixteen metric taps and dies.
The Irwin is fairly well reviewed for moderate use. It works with a variety of metals, and the only real customer complaint is that the handle tends to loosen up a little bit over time, causing some slippage.
For the most part, the Irwin handles delicate work well but is durable enough that it can be used on more robust projects as well. The fact that it works in metric and standard is also a huge selling point for many, eliminating the need for another set.

The Gino set is pretty well reviewed, with most reviewers taking on a “you get what you pay for” mindset. some people had issues with receiving the right taps and dies or with the taps and dies being stamped incorrectly or not at all. Most people view it as a good starter kit, or for people who might only need the set once or twice.

The set also comes with a screwdriver, and the entire set comes in a nice storage case. The dies themselves are rated for alloy steel, carbon, cast iron, aluminum, brass, and bronze.
This Tekton set is fairly well rated. The few complaints have been based on the handles themselves and not the dies. The dies themselves are durable and long-lasting, but the handles get looser over time, leading to damage if the handle slips off in the middle of a project.
This Irwin set is forty-one pieces, with one three millimeter tap and then all four to twelve-millimeter taps coming in both fine and course size.
This makes for nineteen taps in all. Ther set comes with a manufacturer’s inventory and three wrenches, a TR-88, a TR-73, and a TR-50. It also comes with a pitch gauge and a screwdriver. It comes with a plastic case that’s neatly organized.
The set is fairly high reviewed, with high-quality taps and dies, as well as handles that seem to perform better than some of the other contenders on this list.
This set seems to fulfill the mid-range need that many people have when they’re looking for tap and die sets. They need something nice enough that it will last for a while, but not too expensive since they’re only using it every so often. The Irwin set also comes nicely packaged and organized, with two trays to hold everything nicely.

This Lang tools set is billed as a set primarily for car restoration. The set itself is SAE, with both fine and coarse threaded taps. There are six fine thread and six coarse thread sizes, with the corresponding dies to match.

The reviews are very good on this set. Customers like the sizes of taps and die available and enjoy the good quality and durability of this set. The overall impression is that for car restoration, this smaller kit is absolutely worth the money and perfect for dealing with the issues that arise during a car rebuild.
The only real complaint seemed to be that the packaging was disposable, meaning that someone would have to purchase a new case or box to keep everything together eventually, as the plastic would break down over time.
5/8 – 24 Tap and Die Set – Single Tap for specific uses
This Merlintools tap and die set includes one 5/8 tap and the corresponding die. The tap is high-speed steel and the threading is extra fine.

There is one handle for both the taps and the dies. The set comes in its own storage case and is rated for use in metal and plastic.
This set reviews well. It’s obviously meant for very delicate work, which means the taps can be easier to break if there’s pressure on the sides, but this is a set meant for micro work, so some care will need to be taken.
Some people are also frustrated with the two-in-one handle since you have to really tighten it to get it to grip the taps. The actual taps and dies themselves stand up well, though a few people have had issues with dulling over time.
The set as a whole stands up well though, and for a few small delicate tasks should serve you well.

What’s the Difference Between a Tap and Die?
A tap is a long, thin tool used for cutting a thread on the interior of a hole. This enables a screw or bolt to thread through the hole. A die is round and squat and is used to cut the bolt or screw, giving it a threaded surface.
Why Use a Tap and Die Set?
A tap and die set can help with converting a typical bolt into a threaded screw or to clean up and perfect an already existing screw. An alternative to tap and die sets is to use machine tapping, which can help to reduce human error and speed up the process.
What Are the Different Types of Taps?
There are a few distinct options when it comes to choosing a tap. First of all, a plug tap is commonly used at the end of a hole and achieves a neat, polished finish. A second tap is used after the first tap (whatever it is) and is responsible for deepening the threads. People use taper taps if they want to initiate a thread. A form tap disperses the material to create a thread form.
What Are the Different Kinds of Dies?
A circular die can produce a thread in one application. Also, the die tapers one side of the thread to make it easier to use. A two-piece adjustable die takes a longer process to make lengthier threads. The procedure calls for closing the die after every thread. If you come across a hex die, this is for applying an exterior thread.
What Materials Make up the Tap and Die Set?
Typically, a tap and die set is made of steel, although the quality of the steel will vary. Less expensive tap and die sets may use lower-grade steel, which is prone to more damage. The majority of the steel used is carbon steel. Stainless steel is corrosion-resistant and reliable, making it another common choice. You may also see alloys made of chromium, molybdenum, and nickel.
What Size Tap and Die Set Do I Need?
A tap and die set may come in metric units or standard American units. Typically, the metric units are used in tap and die sets around the globe while SAE units are used within the United States. SAE International, or the Society of Automotive Engineers, is a professional organization focused on engineering in various industries. They often use SAE to indicate the United States customary units (USCs). An SAE indication is a surefire sign that the tools do not use the metric system. That being said, a decent tap and die set will most likely include a variety of sizes for both the taps and the dies. For example, the plug taps might range in size from 3 x .50 to 12 x 1.75. Different projects will require specific sizes so it helps to get a tap and die set that includes multiple sizes.
How Much Does a Tap and Die Set Cost?
The price is going to depend on several factors. These include the brand, how many accessories and tools are in the set, the quality of the materials used, and the range of sizes within the set, among other things. Because of this, there are large variations in price. Some sets are just $25 while others are several hundred dollars.
How Do You Use a Tap and Die Set?
A tap and die set is used to create new interior threads within a hole. To do that, you first need to choose the correct drill bit to create a new hole that will fit the bolt you want to use. You can drill into any piece of metal that you have lying around. This metal piece is referred to as the “female” part since it is the portion that the bolt is inserted into. Once you have drilled the hole, you can try to tap it, or thread it. You can use a thread pitch gauge to see how far apart the threads should be. Keep in mind that the threads should be a little bit bigger than the hole so that the bolt or screw can fit in. When you have chosen your thread size, you can attach the tap to a manual drill bit and place the tip of the tap into the hole. Press it into the hole, keeping the tap perpendicular to the hole. You should see bits of metal come off to form the threads as you twist the tap carefully. You’re essentially cutting into metal so use caution and be patient.
Can I Remove a Broken Bolt with a Tap and Die Set?
Yes. First, you need to drill a hole into the center of the broken bolt so choose the appropriate drill bit size. Once you drill the hole in the center, you should be able to lock a pair of vice grips into the broken bolt. From there, insert the tap and use a counterclockwise motion to screw it into the hole that you created. When the tap is tight enough, you can start using the extractor to unscrew the broken bolt and get it out of its metal surface.
What Is the Best Brand of Tap and Die Sets?
If you are in the market for a new tap and die set, then you may be wondering which brands are the best. Well, the term “best” is a bit subjective because it depends on several factors such as what your price range is and how big of a set you’re looking for. That being said, some of the most reputable brands out there include Irwin, Tekton, GearWrench, and Neiko but there are plenty of others. For those looking for an inexpensive tap and die set, Gino Development and Neiko have some sets under $40. Irwin and GearWrench have some deluxe sets that include over 100 pieces. It just depends on what it is that you’re looking for.
The basic function of taps and dies haven’t changed over the years, and neither has their design. However, the components have changed a little bit, with alloys and titanium coatings becoming more the norm. Fortunately, there are still options out there for people who like good-old-fashioned steel.
Wrench style has also changed, with some toolkits changing to two-in-ones and some staying with more traditional T-handles. It’ll be up to the buyer to decide with the version they like more, or simply find less frustrating.
Specialty kits are on the rise also, meaning that you won’t have to buy an entire tap and die kit for the few taps or dies you actually need to use to finish a project. We’re seeing this with specific sizes like larger gauges or micro kits for electronics work. There are also specialty kits for restorers too, so they can buy the tools they need for their specific projects. And of course, you can always just purchase single dies if you only need just one.
This focus on customer needs, and no extras are becoming more and more the norm with tool companies, and it leads to our next trend, not segregating measurement systems anymore.
The mixture of metric and SAE is also becoming more popular, with more users needing tools that fit into more than one measuring system. Often, people own things that aren’t just a metric or SAE.
The old norm used to be having to buy two separate sets, but these days, more and more companies are combining them for customer convenience. The overall effect is tools that are more suited for more people and allow users to choose the best experience for them.
